The SAM4S16 is the first device in the Atmel Corporation's Cortex-M4 processor-based family. Atmel is also unveiling its fifth generation Cortex-M4-based Flash MCUs. Throughout 2012, the Atmel SAM3 and SAM4 families will quadruple the Atmel Cortex-M product portfolio to nearly 200 ARM-based microcontrollers 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 (FPU), expanding the Atmel ARM processor-based device offering into the Digital Signal Controller (DSC) 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, 12-bit ADC and DAC and an external bus interface supporting PSRAM, LCD modules, NOR Flash, and NAND Flash. The company states that the device offers the world’s best hardware code protection and supports Atmel QTouch technology for touch button, slider and wheel functionality, targeting the industrial markets.
Selected members of the Atmel SAM4 family include the Cortex-M4 processor and a floating point unit (FPU). Running ARM DSP library, the Atmel Cortex-M4 based SAM4 family boosts execution speed by 2X for fixed-point and 10X for floating-point DSP algorithms over the Cortex-M3 SAM3 family.
Atmel ARM Cortex-M4 processor-based Flash microcontrollers, planned for market introduction in 2012, will offer up to 2MB Flash, 192KB of SRAM, extensive peripherals that include high-speed USB OTG with on-chip transceiver, Ethernet and CAN and an external bus interface supporting PSRAM, LCD modules, NOR Flash, and NAND Flash. All devices integrate advanced security features using hardware code lock security technology. The SAM4 family offers touch support with Atmel QTouch technology for touch button, slider and wheel functionality.
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 designed to enable designers to select the right price-to-performance combination for their specific needs.
All Atmel ARM processor-based microcontrollers come with a comprehensive integrated development tool and software package. In addition, these products support the Atmel QTouch library that enables button, slider and wheel capability, third party eco-system, customer support and In-System Programming (ISP). The new SAM4 devices are upward, pin-to-pin compatible with the Atmel ARM Cortex-M3 based SAM3 Flash MCU products available today. Availability
The Atmel 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.
