Renesas R5F52106BDFP#30

Overview

R5F52106BDFP#30 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 deep software standby wake-up capability - deployed in industrial control panels requiring deterministic timing and IEC60730-compliant self-diagnostic functions.

For engineers reviewing the R5F52106BDFP#30 datasheet, R5F52106BDFP#30 pinout, R5F52106BDFP#30 application, or R5F52106BDFP#30 equivalent, this page delivers verified package mapping (PLQP0100KB-A, 100-pin LQFP), confirmed peripheral channel counts (6-channel MTU2, 6-channel TPU, 12-channel SCI), validated low-power modes (deep software standby with RTC active), and two field-validated alternative parts with documented functional trade-offs.

Technical Context

The R5F52106BDFP#30 implements the RXv1 CPU core with CISC Harvard architecture, 5-stage pipeline, and variable-length instructions enabling ultra-compact code density. It integrates an Event Link Controller (ELC) that routes 59 event signals directly to peripherals without CPU intervention, enabling synchronized timer-triggered ADC conversions and PWM updates during sleep.

Its clock system includes independent PLL, sub-clock (32.768 kHz), high-/low-speed on-chip oscillators, and Clock Accuracy Check (CAC) circuitry. Power management supports four low-power modes, including deep software standby where only RTC remains active while CPU and most peripherals are halted - critical for battery-backed metering applications.
