Atmel Samples ARM-based MCU with 1MB Embedded Flash

Atmel Corp. has announced early sampling of its 32-bit ARM Cortex-M3-based microcontrollers (MCUs) with 1MB embedded Flash and 128kB SRAM. The Atmel SAM3S16 Cortex-M3 MCU offers high performance, low power and large memory density for applications demanding modern user interfaces including capacitive touch, increased data processing and connectivity.

The Atmel SAM3S16 Cortex-M3 MCU is a member of the Atmel ARM-based family of over 100 products shipping in volume. The new device is pin-to-pin compatible with existing Atmel SAM3N and SAM3S Cortex-M3 MCUs, and also supports In System Programming and development tools from Atmel and third party ecosystem partners. The device operates at a maximum speed of 100MHz with 1024kB Flash and 128kB SRAM and includes a full peripheral set, featuring full-speed USB, high-speed MCI for SDIO/SD/MMC, 4 UART, TWIs, SPI, I2S and an external bus interface supporting PSRAM, NOR Flash, LCD Modules and NAND Flash.

Target applications include medical equipment, building and home control, industrial automation, Machine-to-Machine (M2M), test and measurement, smart grid, and data input/output peripherals for consumer and computing devices.

As one of the leading providers of capacitive touch sensor solutions, Atmel supports capacitive touch buttons, slider and wheel (BSW) capability on the Atmel SAM3S16 Cortex-M3 MCUs through the Atmel QTouch library. The SAM3S16 operates from 1.62V to 3.6V and can achieve 200µA/Mhz in dynamic mode at a low operating frequency; 30mA at 100MHz; and 3µA at 1.8V in back-up mode with the RTC (real-time clock) running.
