RZ/A3UL Feather SoM


1 Ghz 64-bit Arm® Cortex®-A55 CPU
128-Mbit SPI Serial Flash Memory
Feather format
Soon available on DigiKey!

The RZ/A3UL allows you to achieve the full potential of a real-time operating system (RTOS) while leveraging the performance boost provided by the 64-bit Arm® Cortex®-A55 CPU core with a maximum operating frequency of 1 GHz. Integrating the Octal-SPI memory interface we conveniently packaged it in a Feather format.

Beside the processor the Feather SoM contains the classic Feather features: GPIOs (both analog and digital), I2C and SPI communication pins, UART pins, a LiPo battery power plug, and the USB programming port. The SoM also features a USB Type-C for powering the board and for USB debug upload.

RTOS compatible

Developed in partnership with the world’s leading chip companies over an 18-year period, and now downloaded every 170 seconds, FreeRTOS is a market-leading real-time operating system (RTOS) for microcontrollers and small microprocessors.
