Product details
Overview
R5F51114ADFL#3A from Renesas is a 32-bit RX CPU-based microcontroller operating at up to 32 MHz (50 DMIPS), featuring 96 KB on-chip flash, 16 KB SRAM, 8 KB data flash, 14-channel 12-bit A/D converter, USB 2.0 full-speed host/function/OTG, and RTC - designed for compact industrial control and low-power embedded systems with integrated analog and communication peripherals.
For engineers reviewing the R5F51114ADFL#3A datasheet, R5F51114ADFL#3A pinout, R5F51114ADFL#3A application, or R5F51114ADFL#3A equivalent, key selection criteria include its 48-pin LFQFP (PLQP0048KB-A) package, −40°C to +85°C temperature grade, USB OTG support, dual 8-bit D/A channels, and E2 data flash endurance of 1,000,000 erase/write cycles.
Technical Context
The R5F51114ADFL#3A implements the RXv1 CPU core with Harvard architecture, five-stage pipeline, and variable-length instructions - enabling ultra-compact code and single-cycle instruction execution. It integrates a dedicated clock frequency accuracy measurement circuit (CAC) and independent watchdog timer (IWDT) with 15 kHz on-chip oscillator for IEC 60730 compliance.
Its event link controller (ELC) enables direct module-to-module triggering without CPU intervention, while the data transfer controller (DTC) supports chain transfers across four modes. The MCU supports little-endian or big-endian data arrangement and includes a 64-bit accumulator for single-instruction 32×32 multiplication results.
