Environmental
CryptoCompanion is guaranteed to operate over the industrial temperature range of -40° to 85° C. ESD is rated at 3KV,
Human Body Model.
1.3.5.
TWI Input/Output Operation
CryptoCompanion communicates to the system using a two wire interface (TWI), which is similar to SMBus. The chip
operates as a slave and does not support clock stretching. This two wire protocol is identical to that supported by the
Atmel AT24C16B serial EEPROM chips. Please see that datasheet on the Atmel web site for detailed timing and
protocol information.
