Product details
Overview
R5F51306BGFL#30 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 outputs, capacitive touch sensing (24 keys), and IEC60730-compliant safety functions for industrial control panels.
For engineers reviewing the R5F51306BGFL#30 datasheet, R5F51306BGFL#30 pinout, R5F51306BGFL#30 application, or R5F51306BGFL#30 equivalent, key selection criteria include its 48-pin LFQFP (PLQP0048KB-B) package, –40°C to +105°C extended temperature rating, integrated RTC with calendar mode, low-power software standby mode (0.37 µA), and ELC-driven event-linked peripheral operation without CPU wake-up.
Technical Context
The R5F51306BGFL#30 implements the RXv1 CPU core with CISC Harvard architecture, 5-stage pipeline, and variable-length instructions-enabling ultra-compact code and single-cycle 32×32-bit multiplication. Its clock system integrates HOCO (32 MHz ±1%), sub-clock (32.768 kHz), PLL, and dedicated IWDT oscillator (15 kHz), with independent ICLK/PCLK/FCLK domains.
Peripheral coordination is managed via Event Link Controller (ELC), supporting 47 event sources and enabling linked module operation (e.g., MTU-triggered ADC conversion) during CPU sleep. The MCU supports IEC60730 Class B compliance through hardware-assisted RAM test (DOC), A/D self-diagnostic, LVD voltage monitoring (14-level detection), and clock accuracy measurement (CAC).
