It targets industrial HMI, smart sensors, and battery-powered control systems requiring real-time performance, secure firmware, and mixed-signal integration.
For engineers reviewing the R5F52317AGFL#30 datasheet, R5F52317AGFL#30 pinout, R5F52317AGFL#30 application, or R5F52317AGFL#30 equivalent, this page delivers verified specifications, package mapping to PLQP0048KB-B (48-pin LFQFP, 7 × 7 mm), functional validation for CAN/USB/RTC/CTSU, and two confirmed alternative parts with documented technical and application differences.
Technical Context
The R5F52317AGFL#30 implements the RXv2 CPU core with Harvard architecture, 5-stage pipeline, and variable-length instructions, delivering deterministic real-time execution at 54 MHz. It integrates an IEEE 754-compliant single-precision FPU, memory protection unit (MPU), and event link controller (ELC) enabling interrupt-free peripheral coordination during CPU sleep.
