Renesas R5F52107BDFB#30

Overview

R5F52107BDFB#30 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, 1 μs conversion), and real-time clock with deep software standby wake-up capability - deployed in industrial control panels requiring deterministic timing and IEC60730-compliant self-diagnostic functions.

For engineers reviewing the R5F52107BDFB#30 datasheet, R5F52107BDFB#30 pinout, R5F52107BDFB#30 application, or R5F52107BDFB#30 equivalent, key selection criteria include its 144-pin LQFP (20 × 20 mm, 0.5-mm pitch) package, full peripheral set including ELC, MPC, RSPI, RIIC, and dual 10-bit D/A outputs, and support for −40°C to +85°C operation with 1.62–5.5 V supply range.

Technical Context

The R5F52107BDFB#30 implements a CISC Harvard architecture with 5-stage pipeline and variable-length instructions, enabling ultra-compact code and fast interrupt response. Its on-chip PLL supports 4–12.5 MHz input to generate 50 MHz system clock (ICLK), while independent peripheral clocks (PCLK up to 32 MHz, BCLK up to 12.5 MHz) allow fine-grained power/performance tuning.

It integrates event-driven operation via the Event Link Controller (ELC), enabling timer, ADC, and communication modules to trigger without CPU intervention - critical for low-power sensor node firmware. The chip version B variant includes full 144-pin peripheral mapping: 12-channel SCIc, 1-channel SCId, 1-channel RIIC, 1-channel RSPI, RTC, 2×10-bit DAC, and 2×2-channel comparators.
