RENR5F52318ADFL#30

Overview

The R5F52318ADFL#30 is a high-performance 32-bit microcontroller from the Renesas RX231 group, featuring an RXv2 core with a built-in Floating Point Unit (FPU) and DSP instructions. Operating at up to 54MHz, it balances computational power with ultra-low power consumption, making it ideal for battery-operated devices that require complex sensor processing or capacitive touch interfaces.

Why Choose This Part

This MCU stands out for its RXv2 core architecture which provides a high CoreMark/MHz ratio and hardware acceleration for floating-point math. It includes 8KB of dedicated data flash for EEPROM emulation and specialized low-power modes that reduce current to 0.8uA in standby, extending battery life significantly.

Applications

Getting Started

Developers should use the Renesas e2 studio IDE or IAR Embedded Workbench for RX. Hardware evaluation is best performed using the Renesas Target Board for RX231 or the RSK (Renesas Starter Kit) for RX231, which supports on-chip debugging via the E2 or E2 Lite emulator.

Also Consider

STM32L431CCT6 STMicroelectronics - Offers similar low-power performance with an ARM Cortex-M4 core and widely available community support.

R5F52318ADFP#30 RENRenesas Electronics - The same RX231 silicon in a 100-pin QFP package for projects requiring more GPIO and peripheral access.
