Introduction
The Atmel AT88CK427GREEN is an Atmel CryptoAuthentication evaluation kit that can be used as a reference design for
USB applications requiring the Atmel CryptoAuthentication product family. The kit includes an Atmel AT90USB162
microcontroller, which provides a convenient USB interface that allows users to understand and experiment with CryptoAuthentication
technology using their personal computer. Developers can also use the provided six-pin interface header to directly connect
the CryptoAuthentication device to an existing project. Complete source code for the AVR and CryptoAuthentication
devices and documentation for the kit, as well as the schematic, Gerber files, and bill of materials, are all downloadable at
www.atmel.com/cryptokits.

User Definable LEDs
The AT88CK427GREEN includes two general-purpose, user-definable LEDs, which are connected to PD4 of the
AT90USB162 MCU, as shown in Figure 1-3. Both LEDs will light when PD4 is configured as an input (hi-Z).
Otherwise, the LEDs will toggle according to Table 1-1. This configuration also serves as a power indicator
because at least one LED is always on when power is applied.

Reset
Although the Atmel AT90USB162 has its on-chip reset circuitry (see the Atmel AT90USB162 datasheet section,
“System control and reset”), the AT88CK427GREEN provides an additional mean to reset the AT90USB162.

Power-on Reset: The onboard RC network acts as power-on reset
Debugging
The AT90USB162 debugWIRE is not accessible on the AT88CK427GREEN, and, therefore, not suitable for code
development. It is recommended that firmware development be done with the Atmel STK®526 or the Atmel
STK600 routing card (STK600-RC032U-20) and the socket card (STK00-TQFP32).
The Atmel STK526 starter kit is dedicated to the AT90USB82/162 microcontrollers. It supports the Atmel JTAGICE
mkII and Atmel AVRISP mkII debuggers via Atmel AVR Studio®. It includes a number demonstration programs with
source and hex files. The parts can be directly programmed through the USB port with the Atmel FLIP (flexible
in-system programmer) utility.

Firmware Upgrade
See the Atmel application note, “Upgrading Crypto/Tempsensor Kit Firmware.”
