AT88CK101 Atmel CryptoAuthentication Development Kit HARDWARE USER GUIDE Atmel CryptoAuthentication AT88CK101 Daughterboard Atmel-8726A-CryptoAuth-AT88CK101-Hardware-UserGuide 112015 Introduction The Atmel CryptoAuthentication AT88CK101 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 ATSHA204A, ATAES132A, ATECC108A, and ATECC508A crypto element devices. The daughter board comes in two different variations with a socket that supports either an 8-lead SOIC or an 8-lead UDFN/XDFN. This kit uses a modular approach, enabling the daughterboard to connect directly to an STK series Atmel AVR or Atmel ARM development platform to easily add security to applications. An optional adapter kit is also available when the 10-pin header on the daughterboard is incompatible. The AT88CK101 2 provides a test point header for the I C, SWI, and SPI signals. The AT88CK101 is sold with the Atmel AT88Microbase module to form the Atmel AT88CK101-XXX Starter Kit. The AT88Microbase AVR-based base board comes with a USB interface that lets designers learn and experiment on their PCs.
