AT88RF1354 SPI User Guide For CryptoRF
1.3
Scope
The
AT88RF1354 SPI User Guide
includes command illustrations and examples necessary to
communicate with a CryptoRF PICC. This document summarizes AT88RF1354 and CryptoRF
device specific details.
All examples assume a microcontroller is being used as a pass-thru device between the PC host
and the reader. The microcontroller translates command and data strings from the host into SPI
format. Likewise all SPI response data from the AT88RF1354 is translated back to strings by the
microcontroller.
Refer to the
AT88RF1354 Datasheet
for electrical details, the
AT88RF1354 Command Reference
Guide
and the
CryptoRF Specification
for complete device detail. Reference Designs and
