Renesas R5F52305ADLF#U0

Overview

R5F52305ADLF#U0 from Renesas is a 32-bit RXv2 microcontroller with 128 KB on-chip flash, 32 KB SRAM, and 54 MHz max operating frequency delivering 88.56 DMIPS. It integrates a single-precision IEEE 754 FPU, 12-bit 24-channel ADC (0.83 µs conversion), dual 12-bit DACs, USB 2.0 full-speed host/function/OTG, CAN, capacitive touch sensing (24 keys), and TSIP-Lite encryption. It targets industrial HMI and embedded control systems requiring real-time responsiveness, secure firmware, and mixed-signal interfacing.

For engineers reviewing the R5F52305ADLF#U0 datasheet, R5F52305ADLF#U0 pinout, R5F52305ADLF#U0 application, or R5F52305ADLF#U0 equivalent, key selection criteria include its 5×5 mm WFLGA-64 package, −40 to +85°C temperature grade, absence of SDHI and CAN modules (per Table 1.3), and support for ELC-triggered peripheral coordination without CPU wake-up.

Technical Context

The R5F52305ADLF#U0 implements the RXv2 CPU core with Harvard architecture, 5-stage pipeline, and variable-length instructions-enabling ultra-compact code and deterministic interrupt latency. Its clock system includes main (1–20 MHz), sub-clock (32.768 kHz), and on-chip oscillators, with PLL enabling 54 MHz ICLK and 48 MHz USB clock generation.

Peripheral integration centers on event-driven operation: the Event Link Controller (ELC) supports 61 event sources for direct module triggering, while the Data Transfer Controller (DTC) and DMA controller (4 channels) offload data movement. Real-time capability is reinforced by MTU2a/TPU timers (6 channels each), RTC with calendar mode, and low-power timer (LPT) active in software standby.
