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.
Builder uses to integrate a larger system module. Each component
consists of a structured set of files within a directory.
The files in a component directory serve the following
The RS232 UART Core implements a method for communication of serial data. The core provides
a simple register-mapped Avalon廬 interface. Master peripherals [such as a Nios廬 II processor]
communicate with the core by reading and writing control and data registers.
