The SAMA5 Xplained Ultra kit is currently available

Atmel launched a new series of Atmel SMART ARM Cortex-A5-based microprocessors (MPUs), delivering the world’s lowest power consumption for all MPUs in its class. 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.

Industry’s Highest Performing 8-bit tinyAVRs with 1kB Flash

At Embedded World 2016, Atmel announced the world’s highest performing, low power, 8-bit MCUs with 1kB Flash memory. ...

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, and built-in PCI-level security targeting industrial Internet of Things (IoT), wearables and point of sale (POS) applications.

Expanding the Atmel 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 is also a great migration path for designers using ARM926-based MPUs looking for higher performance and additional features including low power, higher security, DDR3 support, smaller footprint, audio, USB HSIC and Atmel’s patented SleepWalking technology.

"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.

“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 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."

Featuring an ARM NEON engine, the new SAMA5D2 series delivers 500MHz and 166MHz of system clocking. The memory system includes a configurable 16- or 32-bit DDR interface controller, 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. The user interface system for the SAMA5D2 includes a 24-bit TFT LCD controller, an audio subsystem with fractional PLL, multiple I2S and SSC/TDM channels, a stereo class D amplifier and Digital microphone support.

The security system in the new SAMA5D2 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.
