Overview
R5F51115AGFK#3A from Renesas is a 32-bit RX CPU core microcontroller operating at up to 32 MHz (50 DMIPS), featuring 128 KB on-chip flash, 16 KB SRAM, 8 KB data flash, 12-bit A/D converter (14 channels), USB 2.0 full-speed host/function/OTG, and RTC - deployed in industrial sensor nodes requiring deterministic real-time control and low-power connectivity.
For engineers reviewing the R5F51115AGFK#3A datasheet, R5F51115AGFK#3A pinout, R5F51115AGFK#3A application, or R5F51115AGFK#3A equivalent, key selection criteria include its 64-pin LQFP (PLQP0064GA-A) package, −40 to +105°C extended temperature grade, integrated USB transceiver with BC support, and dual 8-bit D/A outputs - all critical for embedded HMI and battery-powered edge devices.
Technical Context
The R5F51115AGFK#3A implements a CISC Harvard architecture with five-stage pipeline, variable-length instruction encoding, and on-chip debugging via FINE interface. Its clock system integrates PLL, high-speed (32 MHz ±1%) and low-speed (15 kHz) on-chip oscillators, sub-clock (32.768 kHz), and CAC for frequency accuracy validation.
Peripheral coordination is managed by Event Link Controller (ELC), enabling direct module-to-module triggering without CPU intervention, and Data Transfer Controller (DTC) supporting chain transfer across four modes. The MCU supports IEC 60730 Class B compliance with dedicated IWDT, RAM test assist, and voltage monitoring circuits.
