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.

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.
