For engineers reviewing the R5F56604BGFB#10 datasheet, R5F56604BGFB#10 pinout, R5F56604BGFB#10 application, or R5F56604BGFB#10 equivalent, key selection criteria include its 120-MHz real-time performance (709 CoreMark), integrated FPU for floating-point math, dual 12-bit DACs usable as comparator references, CAN FD compliance per ISO 11898-1:2015, and hardware safety features including MPU, Trusted Memory, CRC calculator, and clock accuracy monitoring.

Technical Context

The R5F56604BGFB#10 implements the RXv3 CPU core with single-cycle instruction execution, 32×32→64-bit multiplier, 32/32→32-bit divider, and IEEE 754-compliant single-precision FPU. Its clock system integrates main (8–24 MHz crystal), sub-clock (32.768 kHz), and on-chip oscillators (LOCO/HOCO/IWDT-dedicated), with independent PLL and frequency-division paths for ICLK (up to 120 MHz), PCLKA (120 MHz), PCLKB (60 MHz), PCLKD (60 MHz), and BCLK (40 MHz).

Peripheral integration includes MTU3a (9-channel 16/32-bit timer with complementary PWM and dead-time control), 24-channel S12ADH A/D converter (0.9 µs min conversion time at 60 MHz ADCLK), R12DAb dual 12-bit D/A, CMPC 4-channel analog comparator, REMCa remote control receiver, and ELC for interrupt-free inter-module event linking - enabling deterministic low-latency operation in sleep modes.

FAQ

What is the maximum operating frequency and CoreMark score of the R5F56604BGFB#10?

The R5F56604BGFB#10 operates at a maximum frequency of 120 MHz and achieves 709 CoreMark under benchmark conditions. This performance stems from the RXv3 CPU core's single-cycle instruction execution, 32×32→64-bit hardware multiplier, and zero-wait-state access to 1 Mbyte code flash and 128 Kbyte SRAM - all confirmed in the R01DS0393EJ0100 datasheet Rev.1.00.

Does the R5F56604BGFB#10 support CAN FD, and what standard does it comply with?

Yes, the R5F56604BGFB#10 integrates a CAN FD module compliant with ISO 11898-1:2015, supporting both standard and extended frames. It operates at data rates up to 5 Mbps in FD mode and maintains full backward compatibility with classical CAN 2.0B - verified in Section 1.1 and Table 1.1 of the official datasheet.

What analog peripherals are integrated into the R5F56604BGFB#10?

The R5F56604BGFB#10 integrates a 24-channel 12-bit S12ADH A/D converter (0.9 µs minimum conversion time), two 12-bit R12DAb D/A converters (0–AVCC0 output), and four-channel CMPC analog comparators. The DAC outputs can serve as precision reference voltages for the comparators - all detailed in Sections 1.1 and Table 1.1 of the R01DS0393EJ0100 datasheet.

Is the R5F56604BGFB#10 qualified for extended temperature operation?

Yes, the R5F56604BGFB#10 is the G-version device rated for −40°C to +105°C operation. This is explicitly stated in Table 1.1 (Page 9) and confirmed by the "G" in the part number per Table 1.3 of the R01DS0393EJ0100 datasheet Rev.1.00.

What debugging interfaces does the R5F56604BGFB#10 support?

The R5F56604BGFB#10 supports the FINE (single-wire) debugging interface only - JTAG is omitted in this variant per Table 1.2 of the R01DS0393EJ0100 datasheet. FINE enables full debug, flash programming, and boundary scan functionality with minimal pin count, making it ideal for space-constrained industrial designs.
