SAM7S Series Summary
1. 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 func-
tions 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 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 configu-
ration of the six devices.
Except for the SAM7S32/16, all other SAM7S devices are package and pinout compatible.
Notes: 1. Fractional Baud Rate.
2. Full modem line support on USART1.
3. Only two TC channels are accessible through the PIO.
