SAM3S
Atmel | SMART ARM-based Flash MCU
DATASHEET
Description
The Atmel® | SMART SAM3S series is a member of a family of Flash
microcontrollers based on the high performance 32-bit ARM® Cortex®-M3
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 connection 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,
two 3-channel 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 TFBGA 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 SAM3N, SAM4S series (64- and 100-pin versions) and
SAM7S series (64-pin versions).
