Atmel Corp. has announced the sampling of the SAM4S16, the company's first device in its Cortex-M4 processor-based family. Atmel has also unveiled its fifth generation Cortex-M4 based Flash MCUs.

According to Atmel, throughout 2012, the SAM3 and SAM4 families will quadruple the its Cortex-M product portfolio to nearly 200 ARM-based MCUs and will include devices with on-chip memory densities of up to 2MB Flash, 192KB of SRAM and extensive peripherals including high-speed USB. Several devices in the new Atmel ARM Cortex-M4 Flash family will also include a floating point unit expanding the Atmel ARM processor-based device offering into the digital signal controller market.

The SAM4S16 device operates at a maximum speed of 120MHz with 1024KB Flash and 128KB SRAM with a full peripheral set featuring full-speed USB, high-speed SDIO/SD/MMC, UARTs, TWIs, SPI, I2S, 12bit ADC and DAC and an external bus interface supporting PSRAM, LCD modules, NOR Flash, and NAND Flash. The device claims to offer the world's best hardware code protection and supports Atmel's QTouch technology for touch button, slider and wheel functionality targeting the industrial markets.

Atmel ARM technology-based SAM4 devices are tailored for applications in the medical, power management, motor control, smart metering, industrial automation and embedded audio segments, and offer a scalable solution that enables designers to select the right price-to-performance combination for their specific needs. The SAM4 devices are upward, pin-to-pin compatible with the Atmel ARM Cortex-M3 based SAM3�Flash MCU products available today.

The SAM4S16 is sampling to early customers now. Other devices in the SAM4 family will be introduced throughout 2012. Production quantities of the SAM4S devices will be available in early Q2 2012.
