Atmel's SAM3S series is a member of a family of Flash microcontrollers based on the high per-
formance 32-bit ARM Cortex-M3 RISC processor. It operates at a maximum speed of 64 MHz
and features up to 256 Kbytes of Flash and up to 48 Kbytes of SRAM. The peripheral set
includes a Full Speed USB Device port with embedded transceiver, a High Speed MCI for
SDIO/SD/MMC, an External Bus Interface featuring a Static Memory Controller providing con-
nection to SRAM, PSRAM, NOR Flash, LCD Module and NAND Flash, 2x USARTs, 2x UARTs,
2x TWIs, 3x SPI, an I2S, as well as 1 PWM timer, 6x general-purpose 16-bit timers, an RTC, an
ADC, a 12-bit DAC and an analog comparator.
The SAM3S device is a medium range general purpose microcontroller with the best ratio in
terms of reduced power consumption, processing power and peripheral set. This enables the
SAM3S to sustain a wide range of applications including consumer, industrial control, and PC
peripherals.
It operates from 1.62V to 3.6V and is available in 48-, 64- and 100-pin QFP, 48- and 64-pin
QFN, and 100-pin BGA packages.
The SAM3S series is the ideal migration path from the SAM7S series for applications that
require more performance. The SAM3S series is pin-to-pin compatible with the SAM7S series.
The SAM3S series devices differ in memory size, package and features list.
