Smaller and even more energy efficient CPU Module with Cortex-A5 Core
The DropA5D22 ist a very small and extreme energy efficient.
It provides the newest microprocessor of Atmel, the SAMA5D22. This chip has the right price-to-performance ratio with the world´s lowest power consumption for all MPUs in its class.
Its ARM Cortex-A5 core includes NEON (floating point and parallelizing unit), as well as cryptographic functions like AES, SHA and a true random number generator (TRNG).
Most conspicuous feature of the DropA5D22 is the very small size: we shrinked the board to only 46 mm x 25 mm (1.81 in x 0.98 in) and further decreased power consumption. Supply current in standby mode is less than 1 mA while keeping the entire RAM contents. The DropA5D22 wakes up from standby in well below 0.1 milliseconds.
The Drop boots from its on-board serial flash and/or microSD card, or optionally from external flash memory. DropA5D22 is shipped with a full featured Linux 4.7 operating system.
The comprehensive multiplexing of the 72 PIO-pins provides for various interface configurations.
