Product details
Overview
R5F52106BGFB#10 from Renesas Electronics is a 32-bit RX CPU-based microcontroller operating at up to 50 MHz (78 DMIPS), featuring 256 KB on-chip flash, 32 KB SRAM, 8 KB data flash, 12-bit A/D converter (16 channels, 1 μs conversion), and real-time clock with RTC wakeup from deep software standby. It serves as a main control MCU in industrial HMI panels requiring IEC60730-compliant safety functions.
For engineers reviewing the R5F52106BGFB#10 datasheet, R5F52106BGFB#10 pinout, R5F52106BGFB#10 application, or R5F52106BGFB#10 equivalent, this page delivers verified specifications, package mapping to PLQP0144KA-A (144-pin LQFP), functional pin definitions, IEC60730 self-test support, and two confirmed alternative parts for industrial temperature-grade MCU selection.
Technical Context
The R5F52106BGFB#10 implements the RXv1 CPU core with CISC Harvard architecture, 5-stage pipeline, and variable-length instructions-enabling ultra-compact code and deterministic interrupt latency. Its clock system integrates PLL, sub-clock oscillator (32.768 kHz), high/low-speed on-chip oscillators, and clock accuracy measurement (CAC) for system timing integrity.
Peripheral integration includes ELC for event-driven module activation without CPU intervention, MPC for flexible peripheral pin assignment, and dual watchdogs (WDTA + IWDT) with independent 125-kHz oscillator. The device supports four low-power modes, including deep software standby with RTC active, and operates across −40°C to +105°C.

FAQ
What is the maximum operating frequency and CPU performance of the R5F52106BGFB#10?
The R5F52106BGFB#10 operates at a maximum frequency of 50 MHz and delivers 78 DMIPS of processing performance using the 32-bit RXv1 CPU core. Its single-cycle 32×32 multiply unit, 64-bit accumulator, and 5-stage pipeline enable deterministic real-time execution critical for industrial control loops. This performance level is sustained across the full −40°C to +105°C operating range.
Does the R5F52106BGFB#10 support IEC60730 functional safety compliance?
Yes, the R5F52106BGFB#10 includes dedicated hardware features for IEC60730 Class B and C compliance: self-diagnostic routines for the A/D converter, clock frequency accuracy measurement (CAC), independent watchdog timer (IWDT) with dedicated oscillator, RAM test assistance, and analog input disconnection detection. These are documented in Renesas Application Note R01AN1308.
What package type and pin count does the R5F52106BGFB#10 use?
The R5F52106BGFB#10 uses the PLQP0144KA-A package: a 144-pin LQFP measuring 20 × 20 mm with 0.5 mm pitch, lead-free and RoHS compliant. This package supports all peripherals listed in the RX210 Group datasheet, including full 122 GPIO count, 12-channel SCI, and external bus interface-unlike smaller 100-pin or 64-pin variants.
How does the Event Link Controller (ELC) enhance real-time responsiveness in the R5F52106BGFB#10?
The ELC in the R5F52106BGFB#10 enables direct hardware-to-hardware triggering of 59 event sources-such as starting an MTU2 timer on an external edge or initiating an A/D conversion upon a TPU capture-without CPU intervention or interrupt latency. This reduces jitter in time-critical control tasks and lowers CPU load during high-frequency I/O operations.
What are the key differences between the R5F52106BGFB#10 and R5F52106BDFB#30?
The R5F52106BGFB#10 and R5F52106BDFB#30 share identical flash (256 KB), RAM (32 KB), peripherals, and PLQP0144KA-A package-but differ in operating temperature grade: G-version (−40°C to +105°C) vs. D-version (−40°C to +85°C). Both support IEC60730, ELC, and RTC; the G-version is required for applications exposed to sterilization, outdoor enclosures, or high-ambient industrial settings.
