1. Kit Overview
The EK-RA4M3, Evaluation Kit for RA4M3 MCU Group, enables users to seamlessly evaluate the features of
the RA4M3 MCU group and develop embedded systems applications using Flexible Software Package
(FSP) and e
2
studio IDE. The users can utilize rich on-board features along with their choice of popular
ecosystems add-ons to bring their big ideas to life.
The key features of the EK-RA4M3 board are categorized in three groups (consistent with the architecture of
the kit) as follows:
MCU Native Pin Access
• R7FA4M3AF3CFB144 MCU (referred to as RA MCU)
• 100 MHz, Arm
®
Cortex
®
-M33 core
• 1 MB Code Flash, 256 KB SRAM
• 144 pins, LQFP package
• Native pin access through 4 x 40-pin male headers
• MCU and USB current measurement points for precision current consumption measurement
• Multiple clock sources - RA MCU oscillator and sub-clock oscillator crystals, providing precision
24.000 MHz and 32,768 Hz reference clock. Additional low-precision clocks are available internal to the
RA MCU
