Product details
Overview
R5F51114AGFK#1A from Renesas is a 32-bit RX CPU-based microcontroller operating at up to 32 MHz (50 DMIPS), featuring 96 KB on-chip flash, 16 KB SRAM, 8 KB data flash, 14-channel 12-bit ADC, dual 8-bit DACs, USB 2.0 full-speed host/function/OTG, RTC with calendar mode, and hardware event linking - deployed in industrial HMI, sensor gateway, and USB-connected embedded control systems.
For engineers reviewing the R5F51114AGFK#1A datasheet, R5F51114AGFK#1A pinout, R5F51114AGFK#1A application, or R5F51114AGFK#1A equivalent, key selection criteria include its 64-pin LQFP package (PLQP0064GA-A), −40°C to +105°C extended temperature grade, integrated USB transceiver with BC support, and ELC-driven low-power peripheral coordination without CPU wake-up.
Technical Context
The R5F51114AGFK#1A implements a CISC Harvard-architecture RX core 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 managed via Event Link Controller (ELC), enabling direct module-to-module triggering (e.g., MTU timer → ADC start) while CPU remains in software standby mode. The DTC supports four transfer modes with chain capability, and the USB module complies fully with USB 2.0, supporting host, device, OTG, isochronous transfers, and Battery Charging (BC) v1.2.
