Atmel’s AT91SAM7FP105 is a low pincount FingerChip processor based on the 32-bit ARM

RISC processor. It features a on-chip biometric engine performing enrollment verification and

identification, an internal record cache of up to 25 records and a secure command protocol over

USB, SPI, UART. This protocol enables an external host system or processor to control the onchip

bioengine functions, manipulate the record cache, and securely export record cache

records for external storage. Together with the FingerChip sensor device AT77C104B, it forms

an embedded, secured biometric turnkey solution.
