Overview
R5F51306BDFK#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 (14 channels), two 8-bit D/A outputs, capacitive touch sensing (32 channels), and IEC60730-compliant safety functions. It targets low-power industrial HMI and consumer appliance control where integrated analog peripherals and touch interface are required.
For engineers reviewing the R5F51306BDFK#30 datasheet, R5F51306BDFK#30 pinout, R5F51306BDFK#30 application, or R5F51306BDFK#30 equivalent, key selection criteria include its LQFP-64 (PLQP0064GA-A) package, –40°C to +85°C temperature grade, 1.8–5.5 V single-supply operation, and support for event-driven low-power modes via ELC and LPT.
Technical Context
The R5F51306BDFK#30 implements the 32-bit RXv1 CPU core with Harvard architecture, 5-stage pipeline, and variable-length instructions-enabling 50 DMIPS at 32 MHz. It integrates a dedicated low-speed on-chip oscillator (15 kHz) for IWDT and supports background operation (BGO) for data flash programming.
Its peripheral set includes an Event Link Controller (ELC) enabling interrupt-free module chaining during CPU sleep, a Multi-function Timer Pulse Unit 2 (MTU2) with six 16-bit channels supporting complementary PWM and phase counting, and a Capacitive Touch Sensing Unit (CTSU) configured for up to 32 keys in self-capacitance mode on this 64-pin variant.
