Atmel Introduces Lowest Power ARM Cortex-A5 Based MPU with Leading Security Features for Industrial IoT and Wearable Applications

Atmel launched a new series of Atmel® | SMART ARM® Cortex®-A5-based microprocessors (MPUs). The new  Atmel | SMART SAMA5D2 series delivers the world’s lowest power consumption of any MPUs in its class with leading security features for Industrial IoT, Payment Terminals and Wearable applications.

SAMA5D2 Key Benefits

Expanding the Atmel | SMART SAMA5 family, the SAMA5D2 series delivers just the right price-to-performance ratio for applications requiring an entry-level MPU and extended industrial temperature range (-40 to 105°C ambient temperature). The new series also provides a great migration path for designers using Atmel ARM926™-based MPUs looking for higher performance and an upgraded peripheral set.

Here are some of the new features:

  • DDR controller supporting (LP)DDR3/DDR3L memories
  • QSPI Flash interface with eXecution in Place (XiP) support and on-the-fly decryption
  • Ultra-small 8×8 package with low profile to address space constrained applications
  • New 50µA backup mode with DDR in self-refresh and low-power retention mode with ultra-fast 10µs wake-up
  • High-security grade features to support PCI certified applications
  • Rich audio subsystem with new audio class D amplifier and PDM microphone input
  • USB HSIC inter-chip interface

Target Applications and End Products

  • Small HMI / Control Panel (white goods, alarm systems, etc.)
  • IoT / Secure Gateways
  • POS Terminals and Imaging
  • Wearables / Battery-operated Systems

SAMA5D2 Series Product Details

Featuring an ARM NEON™ engine, the new Atmel | SMART SAMA5D2 series delivers 500MHz and 166MHz of system clocking. The memory system includes a configurable 16- or 32-bit DDR interface controller supporting 16/32-bit DDR2/3/3L, LPDDR/2/3, 16-bit external bus interface (EBI), QSPI Flash interface, ROM with secure and non-secure boot solution, 128kB of SRAM plus 128kB of SRAM configurable as L2Cache or SRAM extension.

The user interface system for the SAMA5D2 devices includes a 24-bit TFT LCD controller, 12-bit Image Sensor Interface with 96MHz pixel clock supporting Raw Bayer, an audio subsystem with fractional PLL, multiple I2S and SSC/TDM channels, a class D amplifier and digital microphone support.

The robust security system in the new SAMA5D2 MPUs includes ARM TrustZone® technology, along with secure boot, hardware encryption/decryption engine, RSA/ECC, on-the-fly decryption of encrypted code, tamper resistance, memory scrambling, independent watchdog, temperature, voltage and frequency monitoring and a unique ID in each device. The SAMA5D2 series consists of seven devices with three different packages:
