SAM4S

AT91SAM ARM-based Flash MCU

Atmel Corporation 

1. Description

The Atmel SAM4S series is a member of a family of Flash microcontrollers based on the high

performance 32-bit ARM Cortex-M4 RISC processor. It operates at a maximum speed of

120 MHz and features up to 2048 Kbytes of Flash, with optional dual bank implementation and

cache memory, and up to 160 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, 2x three channel general-purpose 16-bit timers (with stepper motor and

quadrature decoder logic support), an RTC, a 12-bit ADC, a 12-bit DAC and an analog

comparator.

The SAM4S series is ready for capacitive touch thanks to the QTouch® library, offering an easy

way to implement buttons, wheels and sliders.

The SAM4S 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

SAM4S to sustain a wide range of applications including consumer, industrial control, and PC

peripherals.

It operates from 1.62V to 3.6V.

The SAM4S series is pin-to-pin compatible with the SAM3N, SAM3S series (64- and 100-pin

versions) and SAM7S legacy series (64-pin versions).
