Introduction

Congratulations on acquiring the AVR®-based AT88CK109BSTK3 CryptoAuthentication Starter

Kit. This kit is designed to give designers a quick start to develop code for the CryptoAuthentication

product family. All the necessary hardware is provided in the package. The AT88Microbase has

been pre-programmed for your convenience. Please be sure to visit WWW.Atmel.com/Javan for

the latest firmware image.

1.1 Overview

This document describes the AT88CK109STK3, which is a development kit for the AT88SA100,

AT88SA102, and ATSA8810HS CryptoAuthentication devices. This kit uses a modular approach.

The development kit includes the AT88Microbase board and the AT88CK109BK3

CryptoAuthentication daughter board. The AT88Microbase uses a convenient Type-A USB

interface allowing users to interface with a personal computer and experiment with

CryptoAuthentication. The small USB form factor of the AT88Microbase allows the board to

function as a demo as well as a development platform.

The AT88CK109BK3 daughter board has two SOT23-3 sockets for either client-host or multiple

client development. Together, these boards allow an easy evaluation of the CryptoAuthentication

products using demonstration software. This user guide acts as a general, getting started guide as

well as a complete technical reference for advanced users.

3.2 Power Supply

3.2.1 USB powered

The on-board power supply circuitry allows two possible configurations for the main supply voltage.

Mounted Resistor Main Board

Supply Voltage Comments

R1 3.3V

R2 5.0V ( USB ) Default Setting

The CryptoCompanion supply voltage is always 3.3V, regardless of R1and R2 configuration.

Supply Voltage

*see section 3.2.1

Note 1: For the AT88SA100, AT88SA102, and the AT88SA10HS devices, 5.0V is

required to burn the fuses.

Note 2: The AT88Microbase is shipped with a 16MHz crystal, which allows the

AT90USB1287 on-chip USART to obtain the 230.4K baud rate (-3.5%

error) required to communicate with a CryptoAuthentication device. The

16MHz crystal requires that 5.5VCC5.4



. To operate the

AT88Microbase below 4.5V, the 16MHz crystal must be replaced with an

8MHz crystal. The ABM3B-8.000MHZ-B2-T 8MHz crystal is a drop-in

replacement.

3.2.2 Power LED, “LEDP”

The blue LED (LEDP) is always lit when power is applied to the AT88Microbase regardless of the

voltage supply.

Figure 4. Power on LED “LEDP”

3.3 RESET

Although the AT90USB1287 has its on-chip RESET circuitry, (c.f. AT90USB1287 Datasheet,

section “System Control and Reset”), the AT88Microbase provides two additional means to reset

the AT90USB1287.

3.3.1 Power-on Reset

The on-board RC network acts as power-on RESET.

3.3.2 RESET Push Button

By pressing the RESET push button on the AT88Microbase, a warm RESET of the AT90USB1287

AVR is performed.

3.4 AT90USB1287 AVR Microcontroller

To use the USB interface of the AT90USB1287, the clock source should always be a crystal or an

external clock oscillator (the internal 8MHz RC oscillator cannot be used to operate the USB

interface). Only the following crystal frequencies allow proper USB operations: 2MHz, 4MHz,

6MHz, 8MHz, 12MHz, and 16MHz. The AT88Microbase comes with a default 16MHz crystal

oscillator, which is required to obtain the 230.4K USART baud rate needed for

CryptoAuthentication communication.

3.5 Serial Links

3.5.1 USB

The AT88Microbase is supplied with a standard USB Type-A receptacle. The AT88Microbase only

operates as an “USB device”.

Figure 6. USB Type-A Receptacle

3.5.2 USART

The AT90USB1287 AVR comes with an on-chip USART peripheral (USART1). Only the

asynchronous mode is supported. See section 3.6.3 for pinout details.

3.5.3 SPI / TWI Selector Switch

The SPI – TWI selector switch (K1) allows either the SPI pins (MOSI and SCLK) or the TWI pins

(SDA and SCL) to be routed to the 10 pin Interface header, J1. See section 3.6.3 for pinout details.
