For engineers reviewing the R5F52315CGFP#30 datasheet, R5F52315CGFP#30 pinout, R5F52315CGFP#30 application, or R5F52315CGFP#30 equivalent, key selection criteria include its 100-pin LFQFP package, −40 to +105°C temperature grade (G version), USB 2.0 full-speed OTG support, 24-channel 12-bit ADC with 0.83 µs conversion time, and CAN channel availability per RX231 Group specification.
Technical Context
The R5F52315CGFP#30 implements the RXv2 CPU core with Harvard architecture, 5-stage pipeline, and variable-length instructions-enabling ultra-compact code and fast interrupt response. It integrates memory protection unit (MPU), on-chip debugging (FINE interface), and event link controller (ELC) for interrupt-free peripheral coordination during CPU sleep.
Its clock system includes 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 independent IWDT oscillator. Power management supports three low-power modes, LPT operation in software standby, and voltage detection across three circuits with configurable thresholds.
