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, includ-
ing 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 secu-
rity 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 cellu-
lar phone. Their aggressive price point and high level of integration pushes their scope of use far
into the cost-sensitive, high-volume consumer market.
The AT91SAM7S512, AT91SAM7S256, AT91SAM7S128, AT91SAM7S64, AT91SAM7S321,
AT91SAM7S32, AT91SAM7S161 and AT91SAM7S16 differ in memory size, peripheral set and
package.
Except for the AT91SAM7S32/16, all other AT91SAM7S devices are package and pinout
compatible.
