Atmel’s fast Cortex-A5 based MPU is low power

Last week, Atmel expanded its ARM Cortex-A5 microprocessor (MPU) portfolio with new SAMA5D3 devices that deliver smaller packaging, extended temperature support and an alternative peripheral mix.

The latest SAMA5D3 devices – designed to neatly balance high performance and low-power operation – also offer an expanded ecosystem with new software and hardware.

“To better meet wearable, portable computing and medical application requirements, we have added a smaller package option to the SAMA5D31 to include a tiny, fine-pitch 12x12mm BGA324 0.5mm ball pitch package,” Jacko Wilbrink, Sr. Director of ARM Products, Atmel Corporation, explained.

“For volumes starting at 100,000 pieces, Atmel offers the SAMA5D3 in-die, facilitating the development of Silicon in Package (SiP) solutions for even smaller form factor designs. Incremental support for the industrial and automotive aftermarket is provided by the new SAMA5D36, a superset device providing a unique combination of user interface (UI) and connectivity features including an LCD, 2x Ethernet ports and dual CAN support.”

As the folks at Electronic Products note, the Cortex-A5 based SAMA5D3 (ATSAMA5D3xA) microprocessor now offers a smaller 12 mm package and -40° to 105°C temperature support. The device – which delivers up to 850 DMIPS at 536 MHz – sips under 150 mW in active mode at maximum speed and boasts a 64-bit advanced interrupt controller, SHA algorithm, AES security support and 192 customer allocated fuse bits.

In addition, the MPU lineup series features an multi-layer internal bus structure and 39 DMA channels, plus support for DDR2/LPDDR/LPDDR2 and MLC NAND flash memory with 24-bit ECC and a floating point math unit (VFPv4). The MPU is also equipped with a 12-channel 12-bit A/D converter, a GbE MAC with 1588 support, a 10/100 Ethernet MAC, two CAN controllers, a four channel 16-bit PWM controller along with many other I/O.
