FAQ

What is the maximum operating frequency and DMIPS rating of the R5F524TCAGFP#11?

The R5F524TCAGFP#11 operates at a maximum frequency of 80 MHz and delivers 153.6 DMIPS performance. This is achieved through the RXv2 CPU core's 5-stage pipeline and variable-length instruction set. The R5F524TCAGFP#11 maintains deterministic interrupt latency critical for motor control loops, with fast interrupt response enabling sub-microsecond reaction to overcurrent events.

Does the R5F524TCAGFP#11 support IEC60730 Class B compliance out of the box?

Yes, the R5F524TCAGFP#11 includes hardware-assisted IEC60730 Class B features: memory protection unit (MPU), clock frequency accuracy measurement circuit (CAC), independent watchdog timer (IWDT) with dedicated oscillator, ADC self-diagnostic and disconnection detection, and RAM test assistance via the data operation circuit (DOC). These features are documented in the R01DS0257EJ0200 datasheet and enable certified implementations without external safety monitors.

What package type and pin count does the R5F524TCAGFP#11 use?

The R5F524TCAGFP#11 uses a 100-pin LFQFP package (PLQP0100KB-B) with 14 mm × 14 mm footprint and 0.5 mm pitch. It provides 80 general-purpose I/O pins, including 60 open-drain outputs and 2 5-V tolerant inputs. This package is pin-compatible with other RX24T Group members in the same footprint, enabling scalable design reuse across performance tiers.

How many simultaneous ADC sampling channels does the R5F524TCAGFP#11 support?

The R5F524TCAGFP#11 supports true simultaneous sampling across three channels using its integrated 3-channel synchronous sample-and-hold circuit in ADC unit 1. This capability is essential for acquiring motor phase currents at identical instants-enabling accurate Clarke/Park transforms in field-oriented control. The R5F524TCAGFP#11 achieves this without external sample-hold ICs or timing-critical software synchronization.

Is CAN interface supported on the R5F524TCAGFP#11, and what standard does it comply with?

Yes, the R5F524TCAGFP#11 integrates one CAN module (RSCAN) compliant with ISO11898-1, supporting both standard (11-bit) and extended (29-bit) frame formats. It includes 16 message boxes for flexible mailbox configuration and is designed for real-time diagnostics and distributed control in industrial networks. The CAN peripheral operates independently of the CPU core, ensuring deterministic message handling even during intensive motor control computation.
