Product details
Overview
R5F51306BDFN#30 from Renesas is a 32-bit RX CPU-based microcontroller in the RX130 Group, 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), dual 8-bit D/A outputs, capacitive touch sensing (36 channels), and integrated RTC with calendar mode. It targets low-power industrial HMI and consumer appliance control where integrated analog peripherals, touch interface, and IEC60730-compliant safety functions are required.
For engineers reviewing the R5F51306BDFN#30 datasheet, R5F51306BDFN#30 pinout, R5F51306BDFN#30 application, or R5F51306BDFN#30 equivalent, key selection criteria include its 80-pin LFQFP package (PLQP0080KB-B), 1.8–5.5 V single-supply operation, software standby current of 0.37 µA, 4.8 µs wake-up time, and support for ELC-triggered peripheral chaining without CPU intervention.
Technical Context
The R5F51306BDFN#30 implements the 32-bit RXv1 CPU core with CISC Harvard architecture, 5-stage pipeline, and variable-length instructions-enabling ultra-compact code and single-cycle 32×32 multiplication. Its clock system integrates high-speed (32 MHz ±1%) and sub-clock (32.768 kHz) oscillators, PLL, and CAC for real-time frequency accuracy monitoring.
Peripheral integration centers on event-driven autonomy: the Event Link Controller (ELC) enables 47 event sources to trigger module operations-including MTU2 timers, A/D conversion starts, and RSPI transfers-while the CPU remains in deep sleep. The DTC supports chain transfer across four modes, and the CTSU unit delivers self- and mutual-capacitance touch sensing with hardware-accelerated signal processing.
