Product details
Overview
R5F51306BDFP#10 from Renesas Electronics is a 32-bit RX130 Group microcontroller with 256 KB on-chip flash, 32 KB SRAM, and 8 KB data flash, operating at up to 32 MHz (50 DMIPS) across 1.8–5.5 V supply. It integrates a 12-bit A/D converter (17 channels), dual 8-bit D/A outputs, capacitive touch sensing (36 channels), RTC, low-power timer, and multiple communication interfaces including SCI, I²C, RSPI, and REMC - deployed in industrial human-machine interfaces and appliance control systems.
For engineers reviewing the R5F51306BDFP#10 datasheet, R5F51306BDFP#10 pinout, R5F51306BDFP#10 application, or R5F51306BDFP#10 equivalent, key selection criteria include its 100-pin LFQFP (PLQP0100KB-B) package, –40°C to +85°C temperature grade, IEC60730-compliant self-test features, and support for event-driven low-power operation via ELC and software standby mode (0.37 µA).
Technical Context
The R5F51306BDFP#10 implements the 32-bit RX CPU core with CISC Harvard architecture, 5-stage pipeline, and variable-length instructions-enabling single-cycle 32×32-bit multiply and fast interrupt response. Its clock system includes high-speed on-chip oscillator (32 MHz ±1%), sub-clock (32.768 kHz), PLL, and CAC for frequency accuracy monitoring.
Peripheral integration centers on event-driven autonomy: ELC links 47 event sources (e.g., timer overflows, ADC completions) directly to modules without CPU intervention; DTC supports chain transfers triggered by interrupts; and REMC units decode infrared remote patterns with 8-byte buffers and four-match detection per channel.
