1. Introduction
Atmel®AT88CK101BK8 is a daughterboard that interfaces with a mcu board via a 10-pin header. The
daughterboard has a single 8-pin SOIC socket which can support the Atmel ATSHA204. This kit uses a
modular approach, enabling the daughterboard to connect directly to an STK series AVR development
platform to easily add security to applications. An optional adapter kit is also available when the 10-pin
header on the daughterboard requires a different pinout. The AT88CK101BK8 also provides a test point
header for the I2C, SWI, and SPI signals. The AT88CK101BK8 is sold with the Atmel AT88Microbase
module to form the Atmel AT88CK101STK8 starter kit. The AT88Microbase AVR base board comes with a
USB interface that lets designers learn and experiment on their PCs.
