Description
Atmel’s SAM7S 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 SAM7S32 and SAM7S16), 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 SAM7S 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 SAM7S 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.
