Product Summary
Atmels 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 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.
The AT91SAM7S Series system controller includes a reset controller capable of managing the
power-on sequence of the microcontroller and the complete system. Correct device operation
can be monitored by a built-in brownout detector and a watchdog running off an integrated RC
oscillator.
The AT91SAM7S Series are general-purpose microcontrollers. Their integrated USB Device
port makes them ideal devices for peripheral applications requiring connectivity to a PC or cellular phone. Their aggressive price point and high level of integration pushes their scope of use far
into the cost-sensitive, high-volume consumer market.
