SAM3S Summary
1. SAM3S Description
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, a
ADC, a 12-bit DAC and an analog comparator.
The SAM3S series is ready for capacitive touch thanks to the QTouch library, offering an easy
way to implement buttons, wheels and sliders
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 able 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 SAM7Sseries.
