FAQ

What is the maximum operating frequency and core type of the R5F51405AGFK#30?

The R5F51405AGFK#30 features a 32-bit RXv2 CPU core with a maximum operating frequency of 48 MHz, achieving 204 CoreMark performance. Its on-chip high-speed oscillator (HOCO) delivers ±1% accuracy without requiring an external crystal, and the core includes a hardware FPU compliant with IEEE-754 for single-precision floating-point operations - critical for real-time motor control and sensor fusion algorithms in the R5F51405AGFK#30.

Does the R5F51405AGFK#30 support CAN communication, and what version is implemented?

Yes, the R5F51405AGFK#30 integrates one channel of the RSCAN CAN module compliant with ISO 11898-1, supporting both standard and extended frames at up to 1 Mbps. This implementation includes 16 mailboxes for flexible message filtering and prioritization, and it operates independently of the CPU via the Event Link Controller - enabling deterministic CAN handling in time-critical applications using the R5F51405AGFK#30.

What are the memory resources available on the R5F51405AGFK#30?

The R5F51405AGFK#30 provides 128 KB of on-chip flash memory (programmable at 1.8 V), 32 KB of zero-wait-state SRAM, and 8 KB of data flash rated for 1,000,000 program/erase cycles. The flash supports background operation (BGO), allowing code execution during reprogramming - essential for field firmware updates. All memory resources are directly accessible by the RXv2 core without external bus expansion in the R5F51405AGFK#30.

How many analog-to-digital converter channels does the R5F51405AGFK#30 support, and what is its conversion speed?

The R5F51405AGFK#30 integrates a 12-bit S12ADE A/D converter with 15 external input channels (AD00–AD14) and one internal channel (temperature sensor). At maximum ADCLK of 48 MHz, it achieves a minimum conversion time of 0.67 µs per channel. Sampling time is configurable per channel, and it supports scan, group, and double-trigger modes - making it suitable for high-fidelity current sensing in motor control applications using the R5F51405AGFK#30.

What is the operating temperature range and package type of the R5F51405AGFK#30?

The R5F51405AGFK#30 is rated for operation from –40°C to +105°C (G-grade) and is housed in a 64-pin LQFP package (PLQP0064GA-A), measuring 14 × 14 mm with 0.8 mm pin pitch. This package supports standard surface-mount assembly processes and provides adequate thermal dissipation for industrial and automotive under-hood applications - a key specification distinguishing the R5F51405AGFK#30 from commercial-grade variants.
