Atmel CryptoAuthentication Starter Kit Atmel AT88CK109BK8 Hardware User Guide Features Contents Two 8-lead SOIC sockets Atmel AT88CK109BK8 daughterboard Supports the Atmel ATSHA204 CryptoAuthentication IC Supports communication protocols 2 - I C - SWI (Single wire interface) Power LEDs 1. Introduction Atmel AT88CK101BK8 is a daughterboard that interfaces with a mcu board via a 10-pin header. The daughterboard has two 8-pin SOIC sockets which can support HOST and CLIENT development with an Atmel ATSHA204 device. 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 AT88CK109BK8 is sold with the Atmel AT88Microbase to form the Atmel AT88CK109STK8 starter kit. The AT88Microbase AVR base board comes with a USB interface that lets designers learn and experiment on their PCs. Figure 1-1.
