RENR5F51115ADFM#1A
Overview
The R5F51115ADFM#1A is a 32-bit microcontroller from the Renesas RX111 group, designed for ultra-low power consumption and high-performance processing via the RX CPU core. It operates up to 32MHz and integrates 128KB of Flash memory along with 16KB of RAM and 8KB of dedicated Data Flash for EEPROM-like storage. This MCU is particularly suited for battery-powered applications requiring a balance of low standby current and efficient execution of DSP instructions.
Why Choose This Part
The RX111 core features a 5-stage pipeline and fast interrupt handling, delivering high code efficiency and deterministic response times. Its extremely low power profile, reaching 0.44uA in standby, allows for years of operation on small lithium batteries. The inclusion of an Event Link Controller enables hardware modules to interact directly, significantly reducing power consumption by avoiding CPU intervention for routine tasks.
Applications
Key Specifications
Getting Started
Developers can use the Renesas e2 studio IDE or IAR Embedded Workbench for RX to write and debug code. For hardware evaluation, the Renesas Target Board for RX111 provides a cost-effective platform to test the MCU's low-power modes and peripheral functionality. Programming is typically performed using an E2 or E2 Lite on-chip debugging emulator.
