RENR5F51403ADFL#30
Overview
The R5F51403ADFL#30 is a 32-bit microcontroller from the Renesas RX140 group, featuring an RXv2 core with an integrated FPU and DSP instructions. Operating at up to 48MHz, it provides a balance of high computational performance and ultra-low power consumption, making it ideal for battery-operated devices and industrial sensing. It includes 64KB of Flash, 16KB of SRAM, and a dedicated 4KB Data Flash for EEPROM-style storage.
Why Choose This Part
This MCU stands out due to its RXv2 core which delivers high performance per MHz and efficient code density through variable-length instructions. The inclusion of a hardware FPU and DSP capabilities at a low clock speed allows for complex math without the power penalty of high-frequency operation. Additionally, its wide operating voltage range of 1.8V to 5.5V ensures compatibility with diverse power sources.
Applications
Getting Started
Developers can use the Renesas e2 studio IDE or IAR Embedded Workbench for RX to begin firmware development. Hardware evaluation is best performed using the Target Board for RX140, which provides access to all MCU pins. Practical implementation is supported by the Renesas Software Integration System (SIS) for easy peripheral driver configuration.
