M13-RA6M3-EK_UM - Rev1.0.2 Overview
M13design - 16 Dec. 21 7/53
1 OVERVIEW
1.1 INTRODUCTION
The M13-RA6M3-EK is complete evaluation and development platform for the Renesas Electronics®
32-bit Microcontroller RA family Cortex®-M4 based R7FA6M3AH3CFC microcontroller. The full range of
the hardware features on the board helps users to quickly evaluate all the available peripherals (10/100-
Mbit Ethernet, microSDTM card, USB HS/FS, Audio codec with 4-pole Jack, SDRAM, Quad-SPI Flash
memory,4.3-inch colour LCD-TFT with capacitive touch panel, and many others) and to develop their
custom applications. PMODTM and MikrobusTM connectors make it possible to easily extent the board’s
features (Sensors, communication and network modules and many more). The integrated JLink-OB
debug probe provides in-circuit debug and programming for the RA6M3 device and also a built-in VCOM
functionality.
