TA100 8-Pin SOIC Socket Board User Guide
Introduction
The TA100 8-pin SOIC mikroBUS ™ compatible socket board has been developed for use with any of Microchip’s microcontroller boards that support a MikroElektronika mikroBUS interface. The board’s dimensions match the medium-sized add-on board as defined in the mikroBUS specification. Through use of an adapter board, the socket board can also be used with Microchip microcontroller development boards that support an Xplained Pro Interface.
The TA100 secure elements are one-time-programmable devices. Having a socket board allows for a customer to reuse the board with multiple TA100 sample devices for a given application or for multiple different applications. The
8-pin SOIC socket board is capable of being used with both the I 2 C and SPI interface versions of the TA100 device.

1.2 Board Configuration
TA100 8-Pin SOIC Socket Board Jumper Configurations
• SPI Connections: J3, J4, J5, J6 and J7 in position closest to socket (white band labeled with SPI) (1)
• I 2 C Connections: J3, J4, J5, J6 and J7 in position furthest from socket (white band labeled with I 2 C) (1)

• 5.0V Power: J10 with shunt across 5V and PWR positions (2)
Notes:
1.
Jumpers J3, J4, J5, J6 and J7 must all be set with position pins 1 and 2 shorted (SPI) or all set with position pins 2 and 3 shorted (I 2 C) for proper operation in a given interface mode.
2.
The I/O levels of the GPIO, SPI and I 2 C signals will track with the supply voltage.

Hardware Description
1.3 Supply Current Measurement
The current consumption of the TA100 device can be measured by using the AC164167 8-pin socket board. The only devices on the board that will consume power are the TA100 socketed device, the Power LED and the I 2 C pull-up resistors. Follow these steps to measure the current:
1.
Modify the board to remove the resistor R1 which is in series with the LED. This will remove the current through the LED from the total measured current.
(1)
2.
Install the TA100 device into the socket.
3.
Install the socket board into the host system with the appropriate power settings.
4.
Select either 3.3V or 5V power for the measurement.
(2)
5.
Connect the high side of the ammeter to the 3.3V or 5V supply.
6.
Connect the low side of the ammeter to the common PWR signal of the header.
7.
Current measurements can now be taken by running various TA100 commands and measuring the current. (3)
Notes:
1.
For lower accuracy current measurements this resistor may be kept in the circuit. A separate measurement of the current through just the LED path should be made prior to measuring the TA100 device currents. This value can then be subtracted from the total current measured.
2.
The host board provides the power to the mikroBUS extension board so whichever supply is selected must match the capabilities and setting used on the host board.
3.
When measuring the current of I 2 C devices, the measurement will include the I 2 C pull-up currents used to pull up the bus. For SPI signals the pull-ups are internal to the device and will also factor into the total current consumed.

1.
Option 1: Direct Power from the XPRO Extension
– Determine if the XPRO Board outputs a 3.3V or 5.0V supply voltage.
– Connect the J10 shunt “C”of the AC164167 to the appropriate 3.3V or 5.0V supply.
– Connect the ATMBUSAdapter power shunt “A” to the same voltage as the XPRO Supply.
2.
Option 2: External Power Connected to the ATMBUSAdapter.
– Remove the Power Shunt “A” from the ATMBUSAdapter. This disconnects power from the XPRO Header.
– Connect either 3.3V or 5.0V external power to the Ext Header “B” on the ATMBUSAdapter
– Make sure the J10 shunt on the AC164167 is placed across the correct connections for the External
Power Supply chosen.

Description
The TA100 Configurator GUI provides the ability to configure and pseudo-provision
TA100 devices and to illustrate how the TA100 can be used for various applications such as Secure Boot, Device Authentication and CAN-MAC. These applications perform many cryptographic operations using the TA100 library.
A flexible library implemented with a Hardware Abstraction Layer (HAL) that allows the TA100 to be readily ported to other microcontrollers. The library provides commands support for the TA100 and other Microchip CryptoAuthentication ™ devices significantly speeding up application development.
CRYPTO driver specifications provides an abstraction layer to integrate external cryptographic device such as the TA100 into the AUTOSAR ™ stack. This allows for code to be portable between various applications that use different microcontrollers.
Important: (1) For projects that use the AUTOSAR Driver the AUTOSAR ™ Reference Stack will also be needed. AUTOSAR ™ is an open and standardized automotive software architecture. The TA100 has been integrated into 3rd party AUTOSAR ™ software stacks to aid customers in the implementation of automotive applications. Please contact Microchip for a list of 3rd Party AUTOSAR ™ stack vendors that support the TA100.

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.
• 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.
