Product details
Overview
R5F51114AGFK#3A 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 six communication interfaces - deployed in industrial sensor nodes and low-power HMI control systems.
For engineers reviewing the R5F51114AGFK#3A datasheet, R5F51114AGFK#3A pinout, R5F51114AGFK#3A application, or R5F51114AGFK#3A equivalent, key selection criteria include its 64-pin LQFP (PLQP0064GA-A) package, −40 to +105°C extended temperature grade, integrated E2 data flash endurance (1M erase/write cycles), and hardware-accelerated event link controller (ELC) for interrupt-free peripheral coordination.
Technical Context
The R5F51114AGFK#3A 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 subsystems include a 6-channel MTU2 timer with complementary PWM and phase counting, DTC supporting chain transfers triggered by 82 interrupt sources, and ELC enabling direct module-to-module triggering without CPU intervention - all synchronized to independent ICLK/PCLK/FCLK domains.
