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 I2C and SPI interface versions of the TA100 device.

Figure 1-1. TA100 8-Pin SOIC Socket Board Schematic

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)

• I2C Connections: J3, J4, J5, J6 and J7 in position furthest from socket (white band labeled with I2C)(1)

• 3.3V Power: J10 with shunt across 3V3 and PWR positions(2)

• 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 (I2C) for proper operation in a given interface mode.

2. The I/O levels of the GPIO, SPI and I2C signals will track with the supply voltage.

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 I2C 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 I2C devices, the measurement will include the I2C 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.

2. Connecting the Board

The form factor of the AC164167 development board was chosen because Microchip has heavily adopted the use of

the mikroBUS connector on host boards. Many of Microchip’s development platforms will support one or more

mikroBUS interfaces. These include:

• Microchip Explorer 16/32 Development Board

• MPLAB® Xpress Evaluation Board

• Automotive Networking Development Board

• PIC® Curiosity Boards

• PIC Curiosity Nano Boards

• AVR® Curiosity Nano Boards

• SAM Xplained-Pro microcontroller development boards when used with an ATMBusAdapter

2.1 Xplained Pro Connections

By using an adapter board, the AC164167 development board can still be used with Microchip development boards

that only support the Xplained Pro interface. Figure 2-1 shows the full assembly of the AC164167 TA100 8-Pin SOIC

Socket Board , the ATMBUSADAPTER-XPRO and an ATSAMV71-XULT Development Board.

ATMBUSAdapter Power Settings

The ATMBUSAdapter allows power to be connected to the MikroBus Host adapter either directly through the XPRO

interface or by providing external power through the EXT header. It is important that all jumpers are connected

correctly before connecting to the SAMV71-XULT or other boards with an XPRO interface in order to prevent possible

damage to the system.

Figure 2-2. ATMBUSAdapter Plus AC164167

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.

Microchip to obtain an NDA and request access to the tools. Once an NDA has been signed, these tools will be made

available in the My Secure Software section of the customer’s myMicrochip account. Enhancements, upgrades and

additional tools will automatically be made available to any customer that has been enabled for the TA100 support.

Table 3-1. TA100 Software Tools

Item # Tool Name Description

1 TA100 Configurator

GUI and TA100

Library

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.

2 CryptoAuthLib 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.

3 AUTOSAR™ 4.3.1

CRYPTO driver.(1)

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.
