R7FA6M3AH3CFC
RA6M3 Cortex-M4 microcontroller at 120 MHz with 2 MB flash, a TFT controller and a 2D graphics accelerator.
The R7FA6M3AH3CFC is a Renesas RA6M3 microcontroller with a high-performance Arm Cortex-M4 core running at up to 120 MHz, 2 MB of code flash and a TFT controller with a 2D graphics accelerator and a JPEG decoder, in a 176-pin LQFP package. It is designed for graphical human-machine interface and connected products, where a microcontroller must drive a colour display and run the application at the same time. The Cortex-M4 core with floating-point and DSP instructions provides the compute for graphics and signal processing, and the device includes high-speed USB, Ethernet and a broad set of serial interfaces and converters. Because the RA family shares the Flexible Software Package and a common toolchain, code and drivers move between parts, and a product line can scale from a smaller RA device to this one without rewriting the application. The part suits HMI panels, connected instruments, medical devices and industrial controllers. Every device is factory-traceable and ships with an import declaration, a certificate of origin and RoHS documentation. BeiLuo holds this part in regional stock and our FAE team supports graphics, interface and memory design.
FAE Professional Review
This is the RA part we recommend when a product needs a colour display and real compute. The TFT controller and 2D accelerator offload the graphics from the core, and the large flash holds the application and the graphics assets. Plan the display interface and the memory budget early, and confirm the high-speed interfaces against the external devices, because those are the areas that decide whether the design reaches its performance.

Frequently Asked Questions
What makes it good for graphical HMI?
It includes a TFT controller, a 2D graphics accelerator and a JPEG decoder, so it can drive a colour display without loading the core with every pixel operation.
The 120 MHz Cortex-M4 core runs the application alongside the graphics.
What interfaces does it include?
It provides high-speed USB, Ethernet and a broad set of serial interfaces and converters, which covers a connected HMI or instrument.
Confirm the interface count against your design.
