Renesas R5F52107CDLJ#U0

Overview

R5F52107CDLJ#U0 from Renesas Electronics is a 32-bit RX CPU-based microcontroller operating at up to 50 MHz (78 DMIPS), featuring 384 KB on-chip flash, 64 KB SRAM, 8 KB data flash, 12-bit A/D converter (16 channels), 10-bit D/A converter (2 channels), RTC, ELC, MPC, and IEC60730 compliance functions - deployed in industrial control panels requiring deterministic real-time response and functional safety support.

For engineers reviewing the R5F52107CDLJ#U0 datasheet, R5F52107CDLJ#U0 pinout, R5F52107CDLJ#U0 application, or R5F52107CDLJ#U0 equivalent, this page delivers verified package mapping (100-pin TFLGA, 7 × 7 mm, 0.65-mm pitch), confirmed peripheral channel counts (6 SCI, 1 RIIC, 1 RSPI, 6 MTU2 channels), low-power mode behavior (deep software standby with RTC active), and validated alternative part selection for migration or second-sourcing.

Technical Context

The R5F52107CDLJ#U0 implements a CISC Harvard architecture with 5-stage pipeline, variable-length instructions, and 64-bit accumulator for single-cycle 32×32-bit multiply-accumulate operations. Its clock system integrates PLL, sub-clock oscillator (32.768 kHz), high/low-speed on-chip oscillators, and IWDT-dedicated 125-kHz oscillator - enabling independent domain clocks (ICLK up to 50 MHz, PCLK up to 32 MHz, BCLK up to 12.5 MHz).

It supports four low-power modes (sleep, all-module clock stop, software standby, deep software standby), module stop control, and event-driven operation via ELC - allowing peripherals like MTU2 timers and A/D converters to trigger without CPU intervention. The chip version C variant includes full RTC support, 16-channel A/D with sample-and-hold, and 2-channel 10-bit D/A - distinguishing it from version A/B variants lacking RTC in smaller packages.
