Atmel’s AT91SAM7S is a series of low pincount Flash microcontrollers based on the 32-bit ARM
RISC processor. It features a high-speed Flash and an SRAM, a large set of peripherals, including
a USB 2.0 device (except for the AT91SAM7S32 and AT91SAM7S16), and a complete set
of system functions minimizing the number of external components. The device is an ideal
migration path for 8-bit microcontroller users looking for additional performance and extended
memory.
The embedded Flash memory can be programmed in-system via the JTAG-ICE interface or via
a parallel interface on a production programmer prior to mounting. Built-in lock bits and a security
bit protect the firmware from accidental overwrite and preserves its confidentiality.
