For engineers reviewing the R5F51116AGFL#3A datasheet, R5F51116AGFL#3A pinout, R5F51116AGFL#3A application, or R5F51116AGFL#3A equivalent, key selection criteria include its 48-pin LFQFP (PLQP0048KB-A) package, −40°C to +105°C extended temperature grade, integrated USB transceiver with BC support, and hardware-accelerated ELC/DTC for deterministic real-time control without CPU intervention.
Technical Context
The R5F51116AGFL#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 integrates PLL, high-speed on-chip oscillator (32 MHz ±1%), sub-clock (32.768 kHz), and CAC for IEC 60730 compliance.
Peripheral subsystems include Event Link Controller (ELC) enabling direct module-to-module triggering without CPU wake-up, Data Transfer Controller (DTC) supporting chain transfers across four modes, and MTU2 timer unit with six 16-bit channels supporting complementary PWM, phase counting, and A/D trigger generation - all synchronized to PCLK up to 32 MHz.
