Overview

The R5F52318ADFP#30 is a 32-bit microcontroller from the Renesas RX231 group, featuring an RXv2 core with an integrated Floating Point Unit (FPU) and DSP instructions. Operating at 54MHz, it is designed for applications requiring a balance of high-performance processing and low power consumption, offering 512KB of Flash and 64KB of RAM. It includes specialized hardware for capacitive touch sensing and an Event Link Controller (ELC) to reduce CPU overhead during peripheral interaction.

Why Choose This Part

This MCU offers a high-performance RXv2 core with 4.37 CoreMark/MHz efficiency and a hardware FPU for complex mathematical operations. It provides significant system-level cost savings through integrated safety functions, a dedicated 8KB data flash for EEPROM emulation, and an Event Link Controller that enables autonomous peripheral operation without CPU intervention.

Applications

Capacitive Touch Interfaces
Utilizes the built-in Capacitive Touch Sensing Unit (CTSU) for high-sensitivity, noise-tolerant buttons, sliders, and wheels in consumer and industrial panels.
Battery-Powered Medical Devices
Leverages multiple low-power modes and an 8uA standby current for portable health monitoring equipment.
Industrial Sensor Nodes
Integrates an Analog Comparator and 12-bit ADC with DSP capabilities to process local sensor data before transmission via USB or SCI.
Home Appliance Control
Meets IEC60730 safety compliance requirements for household appliances with features like the Clock Frequency Accuracy Measurement Circuit (CAC).

Getting Started

Development can be performed using the Renesas e2 studio IDE or IAR Embedded Workbench for RX. For hardware evaluation, the Target Board for RX231 is a common entry point, and the E2 Lite emulator is used for debugging. Developers should utilize the Renesas Fit (Firmware Integration Technology) modules to quickly implement USB, touch, and peripheral drivers.
