Its architecture includes a 5-stage pipeline, variable-length instructions, and on-chip FPU compliant with IEEE 754 - enabling deterministic execution for real-time motor control algorithms. The R5F524UCAGFP#30 achieves this performance while maintaining zero-wait-state access to 32 KB SRAM at full speed.

Does the R5F524UCAGFP#30 support IEC60730 Class B functional safety certification?

Yes, the R5F524UCAGFP#30 includes hardware-assisted features for IEC60730 Class B compliance: memory protection unit (MPU), clock frequency accuracy measurement circuit (CAC), independent watchdog timer (IWDT) with dedicated 15-kHz oscillator, data operation circuit (DOC), and ADC self-diagnostic/disconnection detection functions. These capabilities reduce software validation effort for safety-critical industrial applications. The R5F524UCAGFP#30 datasheet explicitly lists these as "useful functions for IEC60730 compliance".

What package type and pin count does the R5F524UCAGFP#30 use?

The R5F524UCAGFP#30 uses the PLQP0100KB-B package: a 100-pin Low-Profile Quad Flat Package with 14 mm × 14 mm body size and 0.5 mm pitch. It is lead-free (Sn-only surface finish) and RoHS compliant. This package provides 79 general-purpose I/O pins, 2 5-V tolerant inputs, and full access to all peripherals including CAN, RSPI, 6×SCI, and 22-channel ADC - matching the functional subset defined for 100-pin RX24U variants.
