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
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.

Section 1

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.

Figure 5. RESET Push Button (AVR RESET) Implementation

AT88SCK109STK3

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.

3.6 On-board Resources

3.6.1 Description of LED Bank

The AT88Microbase includes 3 general purpose red LEDs, which are connected to PD6, PD5 and
PD4. To light an LED, the corresponding port pin must be driven high. To turn off an LED, the
corresponding port pin must be driven low.

Note: AVR can source or sink enough current to drive an LED directly.

3.6.2 Buzzer

The small onboard buzzer adds audio capability to the AT88Microbase board. The buzzer requires
that PD7 be driven with a square wave at

4.0 0.5

KHz to achieve a maximum decibel of 78dB.
