Atmel SAMA5D3 Series Microprocessors Feature ARM Cortex-A5 Core

Atmel Family of Cortex-A5 Processor-Based MPUs

Atmel rolled out their SAMA5D3 series microprocessors. The MPUs are based on the ARM Cortex-A5 core. The Atmel SAMA5D3 MPU is shipping in a 324-ball BGA package. It is in mass production now. Prices start at less than USD $7 for 1,000-piece quantities. The new SAMA5D3 series is ideal for embedded applications in the industrial space, including factory and building automation, smart grid, medical and handheld terminals, along with consumer applications such as smart watches, outdoor GPS, DECT (digital enhanced cordless telecommunications) phones.

The Atmel SAMA5D3 MPUs were developed with 65nm low-power process technology. They feature up to 850DMIPS at 536MHz and 1328MB/s at 166MHz bus speed. The floating point unit (FPU) also provides additional high-precision processing power for image, audio and sensor data. The SAMA5D3 series offers a low-power consumption of less than 200mW in active mode at maximum speed and below 0.5mW in low-power mode when retaining context and offering fast wake-up.

The SAMA5D3 series microprocessors feature a dual Ethernet port (one Gigabit), three high-speed USB ports, dual CAN, TFT LCD controller with graphics accelerator for image composition, camera interface, SDIO/SD/MMC, UARTs, SPIs, TWIs, soft modem, 12-bit ADC and 32-bit timers.
