For engineers reviewing the R5F51116AGFK#1A datasheet, R5F51116AGFK#1A pinout, R5F51116AGFK#1A application, or R5F51116AGFK#1A equivalent, this page delivers verified package mapping (PLQP0064GA-A, 64-pin LQFP, 14 × 14 mm, 0.8 mm pitch), confirmed peripheral channel counts (6 MTU channels, 3 SCI, 1 RIIC, 1 RSPI), real-time clock calendar mode, USB BC support, and low-power software standby recovery in 4.8 μs.

Technical Context

The R5F51116AGFK#1A implements a CISC Harvard architecture with five-stage pipeline and variable-length instructions, enabling ultra-compact code and single-cycle 32×32-bit multiplication. Its on-chip PLL accepts 4–8 MHz input to generate system clock up to 32 MHz, while independent clocks (ICLK, PCLK, FCLK) allow fine-grained power/performance tuning across CPU, peripherals, and FlashIF.

Hardware acceleration includes a Data Transfer Controller (DTC) supporting normal, repeat, and block transfer modes triggered by 82 interrupt sources, and an Event Link Controller (ELC) enabling direct module-to-module triggering without CPU intervention - critical for deterministic low-latency response in motor control and sensor fusion applications.
