Product details
Overview
R5F51113AGNE#2A from Renesas is a 32-bit RX CPU-based microcontroller operating at up to 32 MHz (50 DMIPS), featuring 64 KB on-chip flash, 10 KB SRAM, and 8 KB data flash. It integrates USB 2.0 full-speed host/function/OTG, 12-bit A/D converter (14 channels), 8-bit D/A converter (2 channels), RTC, and operates across −40°C to +105°C for industrial motor control and embedded HMI applications.
For engineers reviewing the R5F51113AGNE#2A datasheet, R5F51113AGNE#2A pinout, R5F51113AGNE#2A application, or R5F51113AGNE#2A equivalent, key selection criteria include USB OTG support with BC (Battery Charger) compliance, 1.0 µs A/D conversion time at 32 MHz, software standby current of 0.44 µA, and HWQFN-48 package compatibility with 7 × 7 mm footprint and 0.5 mm pitch.
Technical Context
The R5F51113AGNE#2A implements a CISC Harvard architecture with five-stage pipeline and variable-length instruction encoding, enabling ultra-compact code and single-cycle instruction execution. Its on-chip peripherals include an Event Link Controller (ELC) for interrupt-free module triggering and a Data Transfer Controller (DTC) supporting chain transfers across four modes.
It features dual clock domains: system clock (ICLK) up to 32 MHz for CPU/core, and peripheral clock (PCLK) independently configurable up to 32 MHz. The high-speed on-chip oscillator delivers 32 MHz ±1% accuracy over −20°C to +85°C, while the sub-clock oscillator (32.768 kHz) feeds the RTC with leap-year and error-adjustment functions.
