New Low-Power MPUs For Industrial IoT And POS Applications


Designers for industrial IoT, wearables and POS applications are demanding more performance, lower power, smaller form factors and additional security for their next-generation applications. The newly launched Atmel SAMA5D2 is well positioned for these demanding requirements, delivering the world’s lowest power MPU, along with low-system cost and PCI level security, as claimed by the company.

According to the press release, the new SAMA5D2 series features an ARM NEON engine, delivers 500MHz and 166MHz of system clocking, 16- or 32-bit DDR configurable memory, 16-bit external bus interface (EBI), QSPI Flash interface, ROM with secure and non-secure boot solution, 128kB of SRAM plus 128kB of L2Cache configurable as SRAM extension.

Adding further, the new MPUs deliver sub 200µA in retention mode with context preserved, 30µs ultra-fast wake-up and a new backup mode with DDR in self-refresh at only 50µA. The Atmel SMART SAMA5D2 series provides great system integration with the addition of a complete audio subsystem, lower pin-count and ultra-small package for space constraints applications, as stated in the release.


Mentioning about the security system offered by the new SAMA5D2, it includes the ARM TrustZone technology, along with secure boot, hardware cryptography, RSA/ECC, on-the-fly encryption/decryption on DDR and QSPI memories, tamper resistance, memory scrambling, independent watchdog, temperature, voltage and frequency monitoring and a unique ID in each device.

“As a leader in ultra-low power MCU and MPU IoT solutions, we are excited to launch the new Atmel SMART SAMA5D2 series for designers requiring a general, entry-level MPU,” said Jacko Wilbrink, Sr. Director of MPUs, Atmel Corporation.

The Atmel SMART SAMA5D2 series price range starts from US$ 4.95 each for 1000 piece quantities. The MPU is readily available for sample testing, but the commercial shipment will start from December 2015 onward, according to the company release.
