Product details
Overview
R5F51114ADLF#UA 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, USB 2.0 full-speed host/function/OTG, 14-channel 12-bit A/D converter (1.0 µs conversion), and dual 8-bit D/A outputs - deployed in industrial HMI, sensor gateway, and USB-connected embedded control systems.
For engineers reviewing the R5F5114ADLF#UA datasheet, R5F51114ADLF#UA pinout, R5F51114ADLF#UA application, or R5F51114ADLF#UA equivalent, key selection criteria include its 64-pin WFLGA (5 × 5 mm, 0.5 mm pitch) package, −40 to +85°C temperature grade, integrated RTC with calendar mode, ELC-driven low-power peripheral linking, and IEC 60730-compliant safety features including CAC and IWDT.
Technical Context
The R5F51114ADLF#UA implements a CISC Harvard-architecture RX core with five-stage pipeline, variable-length instructions, and 64-bit accumulator for single-cycle 32×32 multiply-accumulate operations. Its clock system integrates PLL, high-speed on-chip oscillator (32 MHz ±1%), sub-clock (32.768 kHz), and dedicated IWDT oscillator (15 kHz).
Peripheral coordination is managed via Event Link Controller (ELC), enabling direct module-to-module triggering without CPU intervention - critical for deterministic low-power operation. The Data Transfer Controller (DTC) supports chain transfers across four modes, triggered by 82 interrupt sources including MTU2, SCI, and USB events.
