Product details
Overview
R5F51306BDFN#10 from Renesas is a 32-bit RX CPU-based microcontroller operating at up to 32 MHz (50 DMIPS), featuring 256 KB on-chip flash, 32 KB SRAM, 8 KB data flash, 12-bit A/D converter (17 channels), two 8-bit D/A channels, capacitive touch sensing (36 channels), and IEC60730-compliant safety functions - deployed in industrial control panels requiring low-power operation and integrated analog interfaces.
For engineers reviewing the R5F51306BDFN#10 datasheet, R5F51306BDFN#10 pinout, R5F51306BDFN#10 application, or R5F51306BDFN#10 equivalent, key selection criteria include its 80-pin LFQFP package, 1.8–5.5 V single-supply operation, software standby current of 0.37 µA, 4.8 µs wake-up time, and support for event-driven peripheral coordination via ELC without CPU intervention.
Technical Context
The R5F51306BDFN#10 implements the 32-bit RXv1 core with CISC Harvard architecture, 5-stage pipeline, and variable-length instructions enabling ultra-compact code. It integrates a dedicated multiplication/division unit (1-cycle 32×32 multiply) and 64-bit accumulator for high-precision arithmetic in motor control and sensor processing.
Its clock system includes a 32 MHz ±1% high-speed on-chip oscillator, PLL (4–8 MHz input), sub-clock (32.768 kHz), and independent IWDT oscillator (15 kHz), all managed by the Clock Frequency Accuracy Measurement Circuit (CAC). Peripheral coordination is enabled by the Event Link Controller (ELC), allowing timer-triggered ADC conversions and PWM updates during CPU sleep.
