For engineers reviewing the R5F51118AGFL#3A datasheet, R5F51118AGFL#3A pinout, R5F51118AGFL#3A application, or R5F51118AGFL#3A equivalent, key selection criteria include its 48-pin LFQFP (PLQP0048KB-A) package, −40°C to +105°C extended temperature grade, integrated E2 data flash endurance (1M erase/write cycles), and USB OTG support with BC (Battery Charger) detection capability.
Technical Context
The R5F51118AGFL#3A implements a CISC Harvard-architecture RX CPU core with five-stage pipeline, variable-length instructions, and 64-bit accumulator for single-cycle 32×32 multiply-accumulate operations. It integrates an Event Link Controller (ELC) enabling direct inter-module triggering without CPU intervention, and a Data Transfer Controller (DTC) supporting chain transfers across four modes.
Its clock system includes independent PLL, high-speed on-chip oscillator (32 MHz ±1% over −20°C to +85°C), sub-clock (32.768 kHz), and Clock Accuracy Measurement (CAC) circuit for IEC 60730 compliance. Power management supports software standby mode (0.44 μA) with 4.8 μs wake-up and three low-power states synchronized to PCLK/ICLK/FCLK domains.
