Product details
Overview
R5F51113AGFM#3A 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 with calendar mode, and operates across −40°C to +105°C for industrial motor control and embedded HMI applications.
For engineers reviewing the R5F51113AGFM#3A datasheet, R5F51113AGFM#3A pinout, R5F51113AGFM#3A application, or R5F51113AGFM#3A equivalent, key selection criteria include USB OTG support, 64-pin LFQFP (PLQP0064KB-A) package compatibility, 32 MHz real-time performance with low-power standby (0.44 μA), and IEC 60730-compliant safety features including CAC and IWDT.
Technical Context
The R5F51113AGFM#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 includes high-speed on-chip oscillator (32 MHz ±1%), PLL, sub-clock (32.768 kHz), and dedicated IWDT oscillator (15 kHz).
Peripheral integration centers on event-driven operation via ELC, enabling timer-triggered A/D conversion and module activation without CPU intervention. The DTC supports four transfer modes with chain capability, while MTU2 provides six 16-bit timer channels with complementary PWM, phase counting, and input capture - all configurable per channel via PCLK-divided or external clock sources.
