FAQ

What is the maximum operating frequency and core architecture of the R5F51405AGFM#30?

The R5F51405AGFM#30 features a 32-bit RXv2 CPU core with a maximum operating frequency of 48 MHz. It achieves 204 CoreMark performance at this speed and uses a CISC Harvard architecture with a 5-stage pipeline and variable-length instructions. The core includes an on-chip FPU compliant with IEEE-754 single-precision and a hardware 32-bit divider that completes operations in two clock cycles. These capabilities make the R5F51405AGFM#30 well-suited for deterministic real-time control tasks in industrial applications.

Does the R5F51405AGFM#30 support CAN communication, and what version is implemented?

Yes, the R5F51405AGFM#30 integrates a CAN module compliant with ISO11898-1, supporting both standard and extended frames at up to 1 Mbps. It includes 16 mailboxes for flexible message filtering and prioritization. The CAN peripheral is fully hardware-accelerated and operates independently of the CPU when configured with ELC triggers, allowing efficient bus handling during low-power modes. This implementation makes the R5F51405AGFM#30 suitable for industrial automation networks where deterministic messaging and robust error handling are essential.

What are the analog capabilities of the R5F51405AGFM#30, particularly regarding A/D and D/A converters?

The R5F51405AGFM#30 includes a 12-bit successive approximation A/D converter (S12ADE) with 15 external input channels and a minimum conversion time of 0.67 µs at 48 MHz ADCLK. It also features two independent 8-bit D/A converters with voltage output ranging from 0 V to AVCC0. The A/D supports scan modes, per-channel sampling time control, self-diagnostic functions, and analog input disconnection detection - critical for sensor integrity monitoring in safety-critical systems. These analog resources are fully integrated into the R5F51405AGFM#30's signal chain without requiring external components.

How does the R5F51405AGFM#30 support low-power operation in industrial applications?

The R5F51405AGFM#30 offers four low-power consumption modes: sleep, deep sleep, software standby, and snooze. In software standby mode, it draws just 0.25 µA (typ.) at 25°C and recovers in 6.2 µs using the HOCO 32 MHz clock. The low-power timer (LPT) continues operating during software standby to maintain timing functions, and the sub-clock oscillator drives the RTC for calendar tracking. These features allow the R5F51405AGFM#30 to serve as the primary controller in battery-backed or energy-harvesting industrial nodes while maintaining responsiveness and timekeeping accuracy.

Is the R5F51405AGFM#30 qualified for functional safety standards like IEC60730?

Yes, the R5F51405AGFM#30 includes dedicated hardware features to assist IEC60730 Class B compliance, including self-diagnostic functions for the A/D converter, clock frequency accuracy measurement circuit (CAC), independent watchdog timer (IWDT), and RAM test assistance via the data operation circuit (DOC). These accelerators reduce software verification burden and improve diagnostic coverage. While the R5F51405AGFM#30 itself is not pre-certified, its integrated safety mechanisms are explicitly documented in the hardware manual to support customer-led certification efforts for household and industrial appliances.
