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 120MHz and features up to 2048 Kbytes of Flash, with optional dual bank implementation and cache memory, and up to 160 Kbytes of SRAM. The peripheralset 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).
