Product details
Overview
R5F51306BGFN#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), two 8-bit D/A channels, capacitive touch sensing (36 channels), RTC, and IEC60730-compliant safety functions - deployed in industrial HMI and consumer appliance control systems.
For engineers reviewing the R5F51306BGFN#30 datasheet, R5F51306BGFN#30 pinout, R5F51306BGFN#30 application, or R5F51306BGFN#30 equivalent, key selection criteria include its 80-pin LFQFP package (PLQP0080KB-B), –40°C to +105°C extended temperature grade (G), integrated CTSU for touch interfaces, low-power software standby mode (0.37 µA), and ELC-driven event-linked peripheral operation without CPU wake-up.
Technical Context
The R5F51306BGFN#30 implements a CISC Harvard architecture with 5-stage pipeline and variable-length instructions, enabling ultra-compact code and single-cycle 32×32-bit 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 coordination is managed via the Event Link Controller (ELC), supporting 47 event sources and enabling linked module operation (e.g., MTU-triggered ADC conversion) during CPU sleep. The Data Transfer Controller (DTC) supports normal, repeat, and block transfer modes activated by interrupts, with chain transfer capability for efficient memory-to-peripheral data movement.
