For engineers reviewing the R5F52317BGNE#00 datasheet, R5F52317BGNE#00 pinout, R5F52317BGNE#00 application, or R5F52317BGNE#00 equivalent, this page delivers verified specifications, package mapping, functional alternatives, and design-critical timing, power, and peripheral details required for automotive-grade embedded system integration and IEC 60730-compliant safety firmware development.

Technical Context

The R5F52317BGNE#00 implements the RXv2 CPU core with CISC Harvard architecture, 5-stage pipeline, and variable-length instructions enabling 88.56 DMIPS at 54 MHz. It integrates a single-precision FPU, 32-bit multiplier, and 32-bit divider with two-cycle minimum execution latency.

Its clock system supports independent domain clocks: ICLK (54 MHz system), PCLKA (54 MHz for MTU2a), PCLKD (54 MHz for S12AD), and BCLK (32 MHz for external bus). The ELC enables event-triggered peripheral operation without CPU intervention, supporting low-power synchronized module chaining during sleep states.
