Kit Overview - Renesas RA4 Series User Manual

Renesas RA Family

1. Kit Overview

The EK-RA4E2, an Evaluation Kit for RA4E2 MCU Group, enables users to seamlessly evaluate the features
of the RA4E2 MCU group and develop embedded systems applications using Flexible Software Package
2
(FSP) and e studio IDE. The users can use 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-RA4E2 board are categorized in three groups (consistent with the architecture of
the kit) as follows:
MCU Native Pin Access
•
R7FA4E2B93CFM MCU (referred to as RA MCU)
•
®
100 MHz, Arm Cortex
•
128 kB Code Flash, 40 kB SRAM
•
64 pins, LQFP package
•
Native pin access through 2 x 14-pin and 1 x 40-pin male headers
•
MCU current measurement points for precision current consumption measurement
•
Multiple clock sources - RA MCU oscillator and sub-clock oscillator crystals, providing precision
20.000 MHz and 32,768 Hz reference clock. Additional low-precision clocks are available internal to the
RA MCU
