Overview
R5F51308ADFN#30 from Renesas is a 32-bit RX CPU-based microcontroller operating at up to 32 MHz (50 DMIPS), featuring 512 KB flash, 48 KB SRAM, 8 KB data flash, 17-channel 12-bit ADC (1.4 µs conversion), dual 8-bit DACs, capacitive touch sensing (36 channels), and IEC60730-compliant safety functions for industrial control panels.
For engineers reviewing the R5F51308ADFN#30 datasheet, R5F51308ADFN#30 pinout, R5F51308ADFN#30 application, or R5F51308ADFN#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, and integrated event link controller (ELC) for low-power peripheral coordination without CPU wake-up.
Technical Context
The R5F51308ADFN#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 on-chip peripherals include MTU2 (6-channel 16-bit timer with complementary PWM), SCIg (3 channels), RIIC (1 channel), RSPI (1 channel), REMC (2 channels), and CTSU (36-key capacitive touch).
It supports three low-power modes-sleep, deep sleep, and software standby-with LPT running during standby using sub-clock or IWDTCLK. Clock generation includes HOCO (32 MHz ±1%), LOCO (15 kHz), and sub-clock (32.768 kHz), all monitored by CAC for IEC60730 compliance.
