Introduction
Atmel’s AT91SAM7S256 is a 32-bit ARM RISC processor-based low pincount Flash microcontroller with 256 Kbyte Flash and 64 Kbyte SRAM. Packed with peripherals, including USB 2.0, it minimizes external components. Ideal for 8-bit microcontroller users seeking enhanced performance and extended memory. The in-system programmable Flash, managed via JTAG-ICE or parallel interface, has lock bits and a security bit for firmware protection. The system controller handles power-on sequence, and a built-in brownout detector and watchdog ensure correct operation. With an integrated USB Device port, it suits peripheral applications with PC or phone connectivity. Its competitive price and high integration extend its use into the cost-sensitive, high-volume consumer market.
