Product details
Overview
R5F51117ADFM#3A from Renesas is a 32-bit RX CPU core microcontroller operating at up to 32 MHz (50 DMIPS), featuring 384 KB on-chip flash, 64 KB SRAM, 8 KB data flash, 14-channel 12-bit ADC, dual 8-bit DAC, USB 2.0 full-speed host/function/OTG, RTC, and ELC for event-driven peripheral coordination - deployed in industrial HMI, sensor gateway, and USB-connected embedded control systems.
For engineers reviewing the R5F51117ADFM#3A datasheet, R5F51117ADFM#3A pinout, R5F51117ADFM#3A application, or R5F51117ADFM#3A equivalent, key selection criteria include its 64-pin LFQFP (PLQP0064KB-A) package, −40°C to +85°C temperature grade, integrated USB transceiver with BC support, low-power software standby mode (0.44 μA), and IEC 60730-compliant safety features including CAC and IWDT.
Technical Context
The R5F51117ADFM#3A implements a CISC Harvard-architecture RX CPU with five-stage pipeline, variable-length instructions, and 64-bit accumulator for single-cycle 32×32 multiply-accumulate operations. Its clock system integrates PLL, high-speed on-chip oscillator (32 MHz ±1%), sub-clock (32.768 kHz), and CAC for real-time frequency accuracy monitoring.
Peripheral coordination is handled by the Event Link Controller (ELC), enabling direct module-to-module triggering without CPU intervention - critical for deterministic low-latency responses in motor control and sensor fusion. The Data Transfer Controller (DTC) supports chain transfers across four modes, triggered by 82 interrupt sources including MTU2, SCI, and USB events.
