Product details
Overview
R5F51111ADLM#UA from Renesas is a 32-bit RX CPU-based microcontroller operating at up to 32 MHz (50 DMIPS), featuring 32 Kbytes of on-chip flash, 10 Kbytes of SRAM, and 8 Kbytes of data flash. It integrates a 12-bit A/D converter (14 channels), USB 2.0 full-speed host/function/OTG, RTC with calendar mode, and operates across −40 to +85°C in a 36-pin WFLGA package (4 × 4 mm, 0.5 mm pitch). It targets compact industrial sensors and USB-connected edge nodes.
For engineers reviewing the R5F51111ADLM#UA datasheet, R5F51111ADLM#UA pinout, R5F51111ADLM#UA application, or R5F51111ADLM#UA equivalent, key selection criteria include its 36-pin WFLGA footprint, USB OTG capability with VBUS monitoring, 12-bit ADC timing (1.0 µs min conversion), and support for software standby mode with 4.8 µs wake-up - critical for battery-powered IoT endpoints.
Technical Context
The R5F51111ADLM#UA implements a CISC Harvard-architecture RX CPU core with five-stage pipeline, variable-length instructions, and 64-bit accumulator for single-cycle 32×32 multiply-accumulate operations. Its clock system includes high-speed on-chip oscillator (32 MHz ±1%), sub-clock (32.768 kHz), PLL, and dedicated IWDT oscillator (15 kHz).
Peripheral integration centers on event-driven operation: the Event Link Controller (ELC) enables direct module-to-module triggering without CPU intervention, while the Data Transfer Controller (DTC) supports chain transfers triggered by 35+ event sources - enabling low-latency sensor-to-memory or ADC-to-USB data paths during sleep.
