RA6M3 Arm Cortex-M4 MCU, 120 MHz, 2 MB flash, 640 KB SRAM, graphics LCD controller — LQFP-144
The R7FA6M3AH3CFB#AA0 belongs to the Renesas RA6M3 group of 32-bit microcontrollers. It is built around a 120 MHz Arm Cortex-M4 with FPU, 2 MB of code flash, 64 KB of data flash and 640 KB of SRAM with ECC. Integrated Ethernet, CAN, USB, a graphics LCD controller with 2D drawing engine and JPEG codec, and a security engine make it a fit for HMI panels, industrial gateways and building automation. It operates from 2.7 V to 3.6 V over –40 °C to 105 °C.

FAQ
Is the R7FA6M3AH3CFB#AA0 still active?
Yes. Renesas lists this part as Active. Lead times on the RA6M3 have been long, so plan scheduled orders rather than spot buys where possible.
Can I use the 176-pin RA6M3 instead?
The R7FA6M3AH3CFC#AA0 is the same device in an LQFP-176 package, so it needs a PCB change. Within the 144-pin footprint, check memory size and temperature grade in the part number before substituting.
