For engineers reviewing the R5F52317BGFL#10 datasheet, R5F52317BGFL#10 pinout, R5F52317BGFL#10 application, or R5F52317BGFL#10 equivalent, this MCU delivers IEEE 754-compliant FPU, ELC-driven event-triggered peripheral coordination, low-power software standby with LPT operation, and IEC60730-ready self-diagnostic functions for safety-critical embedded systems.
Technical Context
The R5F52317BGFL#10 implements the RXv2 CPU core with 5-stage CISC Harvard pipeline, 88.56 DMIPS at 54 MHz, and built-in single-precision FPU compliant to IEEE 754. It supports little-endian or big-endian data arrangement and includes memory protection unit (MPU) for secure code execution.
Its clock system integrates main oscillator (1–20 MHz), sub-clock (32.768 kHz), PLL (4–12.5 MHz input), USB-dedicated PLL (4/6/8/12 MHz), and IWDT-dedicated low-speed oscillator. System clock (ICLK) runs up to 54 MHz; peripheral clocks (PCLKA/PCLKD) are independently configurable up to 54 MHz for MTU2a and S12AD modules.
