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

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.
