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.

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.
Figure 7. TWI – SPI Selector Switch

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.
Figure 8. LEDs Implementation Schematic
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.

3.6.4 CryptoCompanion Chip
The AT88Microbase has one CryptoCompanion device (AT88SC108), which is located on the back
side of board. The AT88SC018 is designed as the mate to Atmel’s CryptoRF® (CRF) and
CryptoMemory® (CM) chips. The SCL and SDA pins are connected to PD0 and PD1, respectively.
The RST and PDN pins are connected to PF2 and PF3, respectively.

daughter board.
3.7 AT88CK109BK3 CryptoAuthentication Daughter Board
Figure 13. AT88CK109BK3 Components (top side)
AT88CK109BK3 has two SOT23-3 sockets that support the AT88SA100, AT88SA102, and the
AT88SA10HS 3-leads devices.
Figure 14. Chip-in-Socket Placement (Live bug)
3.8 AT88CK109BK3 HOST and CLIENT Sockets Compatibility
AT88CK109BK3 is supplied with two SOT23-3 sockets titled HOST and CLIENT. Since both
sockets have identical pinout’s, the AT88Microbase can physically accept a host or a client device
in either socket. Therefore, the AT88CK109BK3 can be configured for either a host-client or client-
client development.

Note: When using the demonstration software, the host (AT88SA10HS) and client (AT88SA100 or
AT88SA102) devices must be in their respective sockets according to the “HOST” and “CLIENT”
texts on the board.
3.9 HOST and CLIENT Power Configuration
The AT88CK109BK3 provides the user with the capability to independently power cycle each
socket with software or place the sockets in a constant power-on state, assuming power is applied
to the board.

3.12 Interfacing a USART with CryptoAuthentication
A microcontroller’s USART requires a minimum of two signals (RXD and TXD) to communicate.
The AT88SA100, AT88SA102, and AT88SA10HS devices have a 1-wire communication interface.
The make the USART compatible with a 1-wire CryptoAuthentication device, the USART’s pins (TX
and Rx) are tied together.
Figure 19. USART TXD and RXD pins configured for 1-wire Interfacing
On the AT88CK109BK3, Px2 and Px3 are tied together with a zero ohm resistor (R11). When
mounted to the AT88Microbase, pins Px2 and Px3 align with pins (PB3/PD2) and (PB7/PD3). The
USART pins, PD2 (RXD) and PD3 (TXD), are effectively tied together with R11allowing the USART
to be compatible with the CryptoAuthentication 1-wire interface.
3.13 In-System Programming
3.13.1 Programming with USB bootloader: DFU (Device Firmware Upgrade)
AT90USB1287 AVR comes with a default factory pre-programmed USB bootloader located in the
on-chip boot section of the AT90USB1287. This is the easiest and fastest way to reprogram the
device directly over the USB interface. The “Flip” PC side application, available for free on Atmel
website, offers a flexible and user friendly interface for reprogramming the application over the USB
bus.
The “HWB” push button is used to place the AVR into DFU mode after reset (Refer to
AT90USB1287 datasheet section “boot loader support”).
The following steps enable the DFU mode:
1. Press and hold “HWB” button
2. Press the “RESET” button
3. Release the “RESETT” button.
4. Release the “HWB” button.
For more information about the USB bootloader and FLIP software, please refer to the ‘USB
bootloader datasheet’ document and ‘FLIP User Manual’.
Note: HWBE fuse must be enabled to support DFU.

3.13.2 Programming with AVR JTAG ICE
The AT90USB1287 can be programmed using specific the JTAG link. This sub-section will explain
how to connect and use the AVR JTAG ICE.
Note: When the JTAGEN fuse is disabled, the four TAP pins are normal port pins, and the TAP
controller is in reset. When the JTAGEN fuse is enabled, the input TAP signals are
internally pulled high. This enables the JTAG for Boundary-scan and programming. The
AT90USB1287 device is shipped with this fuse programmed.
Figure 20. Connecting AVR JTAGICE mkII to the AT88Microbase
The Flash, EEPROM and all Fuse and Lock Bit options ISP-programmable, can be programmed
individually or with the sequential automatic programming option.
Note: See AVR Studio® on-line Help for information.
3.14 Debugging
3.14.1 Debugging with AVR JTAG ICE mkII
Every AT88CK109STK3 can be used for debugging with JTAG ICE MK II.
Connect the JTAG ICE mkII as shown in Figure 20, for debugging help; please refer to AVR
Studio® Help information.

AT88SCK109STK3
3-18 AT88CK109STK3 User Guide
8699A—CRYPTO—10/09
When using JTAG ICE MK II for debugging, and as AT90USB1287 parts are factory configured
with the higher security level set, a chip erase operation will be performed on the part before
debugging. Thus the on-chip flash bootloader will be erased. It can be restored after the debug
session using the bootloader hex file available from ATMEL website.
3.15 Test Points
There are 4 test points implemented, these test points are referenced in the full schematics section.
