Xplained Pro

Xplained Pro is an evaluation platform that provides the full Atmel microcontroller experience. The platform consists of a series of Microcontroller (MCU) boards and extension boards that are integrated with Atmel

Studio, have Atmel Software Framework (ASF) drivers and demo code, support data streaming and more.

Xplained Pro MCU boards support a wide range of Xplained Pro extension boards that are connected through a set of standardized headers and connectors. Each extension board has an identification (ID) chip to uniquely identify which boards are mounted on a Xplained Pro MCU board. This information is used to present relevant user guides, application notes, datasheets and example code through Atmel Studio. Available Xplained Pro

MCU and extension boards can be purchased in the Atmel Web Store

1

.

Embedded Debugger

The SAM4E Xplained Pro contains the Atmel Embedded Debugger (EDBG) for on-board debugging. The

EDBG is a composite USB device of three interfaces; a debugger, Virtual COM Port and Data Gateway

Interface (DGI).

In conjunction with Atmel Studio, the EDBG debugger interface can program and debug the ATSAM4E16E. On the SAM4E Xplained Pro, the SWD interface is connected between the EDBG and the ATSAM4E16E.

The Virtual COM Port is connected to a UART port on the ATSAM4E16E (see section

“Embedded Debugger

Implementation” on page 18 for pinout), and provides an easy way to communicate with the target

application through simple terminal software. It offers variable baud rate, parity and stop bit settings. Note that the settings on the target device UART must match the settings given in the terminal software.

The DGI consists of several physical data interfaces for communication with the host computer. See section

“Embedded Debugger Implementation” on page 18 for available interfaces and pinout. Communication

over the interfaces are bidirectional. It can be used to send events and values from the ATSAM4E16E, or as a generic printf-style data channel. Traffic over the interfaces can be timestamped on the EDBG for more accurate tracing of events. Note that timestamping imposes an overhead that reduces maximal throughput. The

DGI uses a proprietary protocol, and is thus only compatible with Atmel Studio.

The EDBG controls two LEDs on SAM4E Xplained Pro, a power LED and a status LED.

Table 3-1, “EDBG LED

Control” on page 6 shows how the LEDs are controlled in different operation modes.

Power LED

Power LED is lit when power is applied to the board.

For further documentation on the EDBG, see the EDBG User Guide

.

Status LED

Activity indicator, LED flashes every time something happens on the EDBG.

The power LED and the status LED blinks simultaneously.

The power LED and the status LED blinks in an alternating pattern.

Hardware Identification System

All Xplained Pro compatible extension boards have an Atmel ATSHA204 CryptoAuthentication™ chip mounted.

This chip contains information that identifies the extension with its name and some extra data. When an

Xplained Pro extension board is connected to an Xplained Pro MCU board the information is read and sent to Atmel Studio. The Atmel Kits extension, installed with Atmel Studio, will give relevant information, code examples and links to relevant documents.

data fields stored in the ID chip with example content.

Power Supply

The SAM4E Xplained Pro kit can be powered either by USB or by an external power source through the 4pin power header, marked PWR. This connector is described in

“Xplained Pro Power Header” on page 10 .

The available power sources and specifications are listed in

Table 3-3, “Power Sources for SAM4E Xplained

Pro” on page 7 .

TARGET USB

The kit will automatically detect which power sources are available and choose which one to use according to the following priority:

1. External power

2. Embedded debugger USB

3. Target USB

External power is required when the 500mA through the USB connector is not enough to power a connected USB device in a USB host application.

Measuring SAM4E Power Consumption

As part of an evaluation of the SAM4E it can be of interest to measure its power consumption. Because the device has a separate power plane (VCC_MCU_P3V3) on this board it is possible to measure the current consumption by measuring the current that is flowing into this plane. The VCC_MCU_P3V3 plane is connected via a jumper to the main power plane (VCC_TARGET_P3V3) and by replacing the jumper with an ammeter it is

possible to determine the current consumption. To locate the current measurement header, refer to Figure 1-1,

“SAM4E Xplained Pro Evaluation Kit Overview” on page 4

.

Warning

3.4

3.4.1

Do not power the board without having the jumper or an ampere meter mounted. This can cause the SAM4E to be powered through its I/O pins and cause undefined operation of the device.

Standard Headers and Connectors

Xplained Pro Standard Extension Header

All Xplained Pro kits have one or more dual row, 20-pin, 100mil extension headers. Xplained Pro MCU boards have male headers while Xplained Pro extensions have their female counterparts. Note that all pins are not always connected. However, all the connected pins follow the defined pin-out described in

Table 3-4, “Xplained


42216A-MCU-01/2014

3.4.2

Pro Extension Header” on page 8 . The extension headers can be used to connect a wide variety of

Xplained Pro extensions to Xplained Pro MCU boards and to access the pins of the target MCU on Xplained

Pro MCU board directly.

Chip Erase Header

There is a 1x2 pin-header that is connected to the SAM4E chip erase pin (PB12) and 3V3 marked ERASE as shown in

Figure 1-1, “SAM4E Xplained Pro Evaluation Kit Overview” on page 4

. This header can be used to chip erase the SAM4E by place a jumper on the header and toggle the power to the board. After the power is toggled the jumper should be removed. Using the chip erase jumper is the only way to erase a chip with the security bit set, an application that immediatly sets invalid clock options or goes into deep sleep withouth any wake-up sources.

Other Headers

In addition to the Xplained Pro standard connectors, SAM4E Xplained Pro has one header with spare signals that offers access to the I/O of the microcontroller which are otherwise not easily available elsewhere or might be favourable to have collected toghether. The headers has a pitch of 2.54mm.

Hardware Revision History and Known Issues

Identifying Product ID and Revision

The revision and product identifier of Xplained Pro boards can be found in two ways, through Atmel Studio or by looking at the sticker on the bottom side of the PCB.

By connecting a Xplained Pro MCU board to a computer with Atmel Studio running, an information window will pop up. The first six digits of the serial number, which is listed under kit details, contain the product identifier and revision. Information about connected Xplained Pro extension boards will also appear in the Atmel Kits window.

The same information can be found on the sticker on the bottom side of the PCB. The sticker on SAM4E

Xplained Pro shows the identifier and revision plain text as A09-nnnn\rr where nnnn is the identifier and rr is the revision. There is also printed a uniqly assigned MAC48 address in hex. A serial number string is embedded in the matrix-barcode located on the sticker.

The serial number string has the following format:

6.2

"nnnnrrssssssssss"

n = product identifier

r = revision

s = serial number

The kit identifier for SAM4E Xplained Pro is 2081.

Revision 3

Revision 3 is the initially released revision, there are no known issues.
