2.1 Electrostatic Warning

WARNING

ESD-Sensitive Electronic Equipment!

The evaluation kit is shipped in a protective anti-static package. The board system must not be subject to high electrostatic potentials.

We recommend using a grounding strap or similar ESD protective device when handling the board in hostile ESD environments (offices with synthetic carpet, for example). Avoid touching the component pins or any other metallic element on the board.

2.2 Power Supply Warning

WARNING

Hardware Power Supply Limitation

Powering the board with voltages higher than 5 VCC (e.g., the 12 VCC power adapters from other kits such as Arduino kits) may damage the board.

User Guide DS50002691B-page 6

32-BIT ARM-BASED MICROPROCESSORS

Evaluation Kit Specifications

WARNING

Hardware Power Budget

Using the USB as the main power source (max. 500 mA) is acceptable only with the use of the on-board peripherals and low-power LCD extension.

When external peripheral or add-on boards need to be powered, we recommend the use of an external power adapter connected to the USB Micro-AB connectors (can provide up to 1.2A on the 3.3V node).

User Guide DS50002691B-page 7

32-BIT ARM-BASED MICROPROCESSORS

Board Powerup

3. Board Powerup

Three sources are available to power up the SAMA5D2C-XULT board:

• USB-powered through the USB Micro-AB connector (J23 - default configuration)

• Powered through the USB Micro-AB connector on the Embedded Debugger (EDBG) interface (J14)

• Powered through a rechargeable battery Li-polymer 3.7V connected to J3 or J4

WARNING

Unlike Arduino Uno boards, the SAMA5D2C-XULT board runs at 3.3V. The maximum voltage that the I/O pins can tolerate is 3.3V. Providing higher voltages (e.g., 5V) to an I/O pin could damage the board.

The sequence for the initial powerup of the board is the following:

1.

Unpack the board, taking care to avoid electrostatic discharge.

2.

Connect the USB Micro-AB cable to the connector J23 (or J14).

3.

Connect the other end of the cable to a free USB port of your PC.

6.3.2.5 Input Power Options

There are several power options for the SAMA5D2C-XULT board.

USB-powered operation is the default configuration, where the USB device port is connected to a PC or a

5V DC supply. The USB supply is sufficient to power the board in most applications. It is important to note that when the USB supply is used, the USB-B Host port has limited power. If USB Host port is required for the application, it is recommended that an external DC supply be used.

The figure below provides the schematics of power options.

Note:  USB-powered operation eliminates additional wires and batteries. It is the preferred mode of operation for any project that requires only a 5V source at up to 500 mA.

6.3.2.6 Battery Supply Source

The ACT8945A features an advanced battery charger that incorporates the ActivePath architecture for system power selection. This combination of circuits provides a complete, advanced battery-management system that automatically selects the best available input supply, manages charge current to ensure system power availability, and provides a complete, high accuracy (±0.5%), thermally regulated, fullfeatured single-cell linear Li+ charger.

The ActivePath circuitry monitors the state of the input supply, the battery, and the system, and automatically reconfigures itself to optimize the power system. If a valid input supply is present,

ActivePath powers the system from the input while charging the battery in parallel. This allows the battery to charge as quickly as possible, while supplying the system. If a valid input supply is not present,

ActivePath powers the system from the battery. Finally, if the input is present and the system current requirement exceeds the capability of the input supply, ActivePath allows system power to be drawn from both the battery and the input supply.

Note: 

1.

Refer to errata NRST .

2.

If the battery does not have a pack embedded thermistor (i.e., battery temperature monitoring), the

TH pin should be connected to ground => short J3 pins 2 and 3.

3.

If no battery is connected on connector J3 or J4, it is recommended that the charging function be disabled in the ACT8945 chip. To do so, write the SUSCHG bit to ‘1’ in APCH register (REG 0x71,

SUSCHG = 1).

Charger Input Interrupts

To facilitate input supply detection and eliminate the size and cost of external detection circuitry, the charger has the ability to generate interrupts based upon the status of the input supply. This function is capable of generating an interrupt when the input is connected, disconnected, or both, when the charger state machine transitions.

Charge Status Indicator

The charger provides a charge-status indicator output, nSTAT. nSTAT is an open-drain output which sinks current when the charger is in an active-charging state, and is high-Z otherwise. nSTAT features an internal 8 mA current limit, and is capable of directly driving an LED (D1).

Precision Voltage Detector

The low battery input (LBI) connects to one input of a precision voltage comparator, which can be used to monitor a system voltage such as the battery voltage. An external resistive-divider network can be used to set voltage monitoring thresholds. The output of the comparator is present at the open-drain low battery indicator output (nLBO) and connected to the red LED D1.

Table 6-3. PIOs Used to Control the Battery Charger

PIO Function

PA12 CHGLEV: Charge Current Selection Input

PB13 nIRQ: Open-Drain Interrupt Output. nIRQ is asserted any time an unmasked fault condition exists or a charger interrupt occurs.

PC8 nLBO: Low Battery Indicator Output. nLBO is asserted low whenever the voltage at LBI is lower than1.2V; it is high-Z otherwise.

6.3.2.7 Backup Power Supply

The SAMA5D2C-XULT board requires a power source to permanently power the backup part of the

SAMA5D2 device (refer to SAMA5D2 Series datasheet). A super capacitor sustains such permanent power to VDDBU when all system power sources are off.

6.3.2.8 Power Supply Control

In the ACT8945A, three DC-DC converters (1.8V, 1.2V, 3.3V) and two LDO outputs are available.

All ACT8945A outputs can be controlled by the TWI interface through software.

The three DC-DC outputs can be enabled or disabled by the SAMA5D2 SHDN output:

• SHDN = 0: The DC-DC output is disabled.

• SHDN = 1: The DC-DC output is enabled.

Two push buttons are also available:

• Wakeup push button: When pressed, the ACT8945A power outputs are restarted if the ACT8945A is in shutdown mode.

• Reset push button: When pressed, the ACT8945A transfers the reset signal to the MPU.

6.3.3 Reset Circuitry

The reset sources for the SAMA5D2C-XULT board are:

• Power-on reset from the power management unit (PMIC)

• Push button reset BP3

• External reset from Arduino connectors

• JTAG or EDBG reset from an in-circuit emulator

The rule of operation is:

• JP9 = OFF (default) → enable normal boot from serial Flash memories mounted on board

• JP9 = ON → booting from optional serial Flash memories is disabled

Refer to the SAMA5D2 Series datasheet for more information on standard boot strategies and sequencing.

Note:  The errata in the SAMA5D2 datasheet state that booting from SD/MMC devices is nondeterministic. In order to have a known behavior regardless of SD/MMC data contents, we recommend SDMMC0/SDMMC1 boot bits be disabled in the Boot Configuration Word fuse.

6.3.6 Additional Memories

6.3.6.1 Serial Flash

The SAMA5D2 provides two high-speed Serial Peripheral Interface (SPI) controllers. One port is used to interface with the on-board serial serial Flash.

The four main signals used in the SPI are Clock, Data In, Data Out, and Chip Select. The SPI is a serial interface similar to the I 2 C bus interface but with three main differences:

• It operates at a higher speed.

• Transmit and receive data lines are separate.

• Device access is chip select-based instead of address-based.

6.3.6.2 QSPI Serial Flash

The SAMA5D2 provides two Quad Serial Peripheral Interfaces (QSPI). One port is used to interface with the optional on-board QSPI serial Flash.

The Quad SPI Interface (QSPI) is a synchronous serial data link that provides communication with external devices in Master mode.

© 2017 Microchip Technology Inc.

User Guide DS50002691B-page 24

32-BIT ARM-BASED MICROPROCESSORS

Board Components

The QSPI can be used in SPI mode to interface to serial peripherals (such as ADCs, DACs, LCD controllers, CAN controllers and sensors), or in Serial Memory mode to interface to serial Flash memories.

The QSPI allows the system to execute code directly from a serial Flash memory (XIP) without code shadowing to RAM. The serial Flash memory mapping is seen in the system as other memories (ROM,

SRAM, DRAM, embedded Flash memory, etc.).

With the support of the Quad SPI protocol, the QSPI allows the system to use high-performance serial

Flash memories which are small and inexpensive, in place of larger and more expensive parallel Flash memories.

6.3.6.3 Serial EEPROM with Unique MAC Address

The SAMA5D2C-XULT board embeds one Microchip AT24MAC402/602 EEPROM using a TWI1 interface.

The AT24MAC402/602 provides 2048 bits of Serial Electrically-Erasable Programmable Read-Only

Memory (EEPROM) organized as 256 words of eight bits each and is accessed via an I 2 C-compatible (2wire) serial interface. In addition, the AT24MAC402/602 incorporates an easy and inexpensive method to obtain a globally unique MAC or EUI address (EUI-48 or EUI-64).

The EUI-48/64 addresses can be assigned as the actual physical address of a system hardware device or node, or it can be assigned to a software instance. These addresses are factory-programmed by Atmel and guaranteed unique. They are permanently write-protected in an extended memory block located outside of the standard 2-Kbit memory array.

In addition, the AT24MAC402/602 provides the value-added feature of a factory-programmed, also guaranteed unique 128-bit serial number located in the extended memory block (same area as the EUI address values).

WARNING

The EEPROM device is also used as a “software label” to store board information such as chip type, manufacture name and production date, using the last two 16-byte blocks in memory. To preserve the ease of board identification by software, the information contained in these blocks should not be modified.

6.4.7 Audio Class D Amplifier

The Audio Class D Amplifier (CLASSD) is a digital input, Pulse Width Modulated (PWM) output stereo

Class D amplifier. It features a high-quality interpolation filter embedding a digitally controlled gain, an equalizer and a de-emphasis filter.

On its input side, the CLASSD is compatible with most common audio data rates. On the output side, its

PWM output can drive either:

• high-impedance single-ended or differential output loads (Audio DAC application) or,

• external MOSFETs through an integrated non-overlapping circuit (Class D power amplifier application).

6.4.13 Embedded Debugger (EDBG) Interface

The Embedded Debugger (EDBG) 1 is an intuitive plug-and-play solution which adds full programming and debugging support to embedded hardware kits containing Microchip microcontrollers and microprocessors. It enables seamless integration between the target hardware and the Atmel Studio front end.

32-BIT ARM-BASED MICROPROCESSORS

Board Components

In addition to the Virtual COM port which provides a UART bridge to the target device, the EDBG provides a Data Gateway Interface, through which the target device and host PC can communicate, facilitating high-level application debugging, monitoring, graphing and logging of system information in real-time.

The EDBG is based on the AT32UC3A4256J high-performance low-power 32-bit AVR microcontroller running at up to 60 MHz. The device includes an on-chip USB 2.0 high-speed hardware module with dedicated DMA channels, making it ideal for data communications.

By default, the EDBG is in Reset state and not usable. To use the EDBG interface, remove the jumper

JP1. To avoid any conflicts with the debug signals, do not use the JTAG and EDBG at the same time.

6.5.1.1 Functions Available Through the Arduino Headers

The multiplexing of the SAMA5D27 I/Os (standard parallel I/O and up to three peripheral functions per pin) makes it possible to route alternate signals via Arduino extension headers. To enable these signals,

SAMA5D27 PIO multiplexing must be properly configured. For more details, refer to

Board Schematics

and the section PIO Controller (PIO) in the SAMA5D2 Series datasheet.

Board Schematics

7. Board Schematics

This section contains the following schematics:

• Block Diagram

• PIO Muxing Table

• Power Supply

• SAMA5D27 – Power

• SAMA5D27 – DDR3

• SAMA5D27 – PIOA and PIOB

• SAMA5D27 – PIOC and PIOD

• SAMA5D27 – SYS, Tamper, and Debug

• USB, ISC, and LCD

• Serial Flash, LEDS, Push Button and ClassD

• Ethernet

• SD and eMMC

• EDBG

• Expansion and XPRO Connectors

Important:  Design Reuse Recommendation

In case the memory or PIO busses go to multiple destinations, series resistors must be added.

These resistors must be located at the beginning of each branch, as close as possible to the

MPU.

In case these connections are point-to-point, the branch resistors found in the following schematics can be removed.

In all cases, it is recommended to always perform routing simulation to check signal integrity prior to PCB manufacturing.

Keep nets as short as possible, therefore, DDR devices have to be placed close as possible of SAMA5D27

The layout DDR should use controlled impedance traces of ZO= 50ohm characteristic impedance.

Address, control and data traces may not exceed 1.3 inches (33.0 mm).

Address, control and data traces must be length-matched to within 0.1 inch (2.54mm).

Address, control and data traces must match the data group trace lengths to within 0.25 inches (6.35mm).

Microchip Devices Code Protection Feature

Note the following details of the code protection feature on Microchip devices:

• Microchip products meet the specification contained in their particular Microchip Data Sheet.

• Microchip believes that its family of products is one of the most secure families of its kind on the market today, when used in the intended manner and under normal conditions.

• There are dishonest and possibly illegal methods used to breach the code protection feature. All of these methods, to our knowledge, require using the Microchip products in a manner outside the operating specifications contained in Microchip’s Data Sheets. Most likely, the person doing so is engaged in theft of intellectual property.

• Microchip is willing to work with the customer who is concerned about the integrity of their code.

32-BIT ARM-BASED MICROPROCESSORS

• Neither Microchip nor any other semiconductor manufacturer can guarantee the security of their code. Code protection does not mean that we are guaranteeing the product as “unbreakable.”

Code protection is constantly evolving. We at Microchip are committed to continuously improving the code protection features of our products. Attempts to break Microchip’s code protection feature may be a violation of the Digital Millennium Copyright Act. If such acts allow unauthorized access to your software or other copyrighted work, you may have a right to sue for relief under that Act.
