1. Description
Atmel’s SAM7S is a series of low pincount Flash microcontrollers based on the 32-bit ARM RISC processor. It fea-
tures 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 acci-
dental 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.
1.1 Configuration Summary of the SAM7S512, SAM7S256, SAM7S128, SAM7S64, SAM7S321,
SAM7S32, SAM7S161 and SAM7S16
The SAM7S512, SAM7S256, SAM7S128, SAM7S64, SAM7S321, SAM7S32, SAM7S161 and SAM7S16 differ in
memory size, peripheral set and package. Table 1-1 summarizes the configuration of the six devices.
Except for the SAM7S32/16, all other SAM7S devices are package and pinout compatible.
