Atmel-11100G-ATARM-SAM4S-Datasheet_27-May-14

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 to connect to SRAM, PSRAM, NOR Flash,

LCD Module and NAND Flash, two USARTs, two UARTs, two TWIs, three SPIs,

one I2S, as well as one PWM timer, two three-channel general-purpose 16-bit

timers (with stepper motor and quadrature decoder logic support), one RT C, one

12-bit ADC, one 12-bit DAC and one analog comparator.
The SAM4S series is  ready for capacitive touch, offering native support for the

Atmel QTouch

®

 library for easy implementation of buttons, wheels and sliders.

The SAM4S device is a medium-range general-purpose microcontroller with the

best ratio in terms of red uced power consumption, processing power and

peripheral set. This enables the SAM4S to sustain a wide range of applications

that includes 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 (48-,

64- and 100-pin versions), SAM4N and SAM7S legacy series (64-pin versions).
