For engineers reviewing the R5F51117AGFM#3A datasheet, R5F51117AGFM#3A pinout, R5F51117AGFM#3A application, or R5F51117AGFM#3A equivalent, this page delivers verified specifications, package mapping to PLQP0064KB-A (64-pin LFQFP, 10 × 10 mm, 0.5 mm pitch), functional pin roles, real-world use cases, and validated alternative parts for design-in and supply continuity.
Technical Context
The R5F51117AGFM#3A implements the RXv1 CPU core with Harvard architecture, five-stage pipeline, and variable-length instructions - enabling deterministic 32-bit arithmetic including 64-bit accumulator results from single-cycle 32×32 multiply operations. Its clock system integrates PLL, high-speed on-chip oscillator (32 MHz ±1%), sub-clock (32.768 kHz), and CAC for IEC 60730 compliance.
Peripheral integration includes Event Link Controller (ELC) for interrupt-free module triggering, Data Transfer Controller (DTC) supporting chain transfers across four modes, and MTU2 with six 16-bit timer channels offering complementary PWM, phase counting, and A/D trigger generation - all synchronized to PCLK up to 32 MHz.
