Atmel SAM4S ARM Cortex™-M4 Flash MCUs

Atmel SAM4S ARM Cortex™-M4 Flash Microcontrollers (MCUs) extend the Atmel Cortex-M portfolio to offer increased performance and power efficiency and higher memory densities with up to 2MB of Flash and 160KB of SRAM. Atmel SAM4S MCUs offer a rich peripheral set for connectivity, system control, and analog interfacing. Devices are pin-to-pin and software compatible with SAM3 and SAM 3N Cortex-M3 processor-based MCUs, offering a smooth upwards migration path for performance and memory size.

The SAM4S operates at 120MHz and integrates Atmel's Flash read accelerator and optional cache memory to increase system performance. These devices feature a multi-layer bus matrix, multi-channel direct memory access (DMA) and distributed memory to support high data rate communication. The SAM4S series achieves 200µA/MHz in dynamic mode at a low operating frequency; and 1µA at 1.8V in back-up mode with the real-time clock (RTC) running.

Features
  • Maximum operating speed of 120MHz
  • 1MB of Flash and 128KB of SRAM
  • 1.62V to 3.6V supply
  • Power consumption 200µA/MHz in dynamic mode at low operating frequency, 30mA at 100MHz and 3µA at 1.8V in back-up mode with the RTC running
  • External bus interface supports SRAM, PSRAM, NOR Flash, LCD module and NAND Flash
  • Extensive peripheral set for connectivity, system control and analog interfacing
  • Native support for Atmel QTouch® capacitive touch technology for implementation of buttons, sliders and wheels
  • Pin-to-pin compatible with Atmel SAM7S, SAM3N and SAM3S MCUs
  • Parallel Input/Output (IO) data capture mode
