Technical Context

The R5F56609CDFB#30 implements the RXv3 CPU core with single-cycle instruction execution, IEEE 754-compliant single-precision FPU, and collective register bank save for fast context switching. 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 settings for ICLK (up to 120 MHz), PCLKA (120 MHz), PCLKB (60 MHz), PCLKD (60 MHz), FCLK (60 MHz), and BCLK (40 MHz).

Peripheral integration includes MTU3a (9-channel 16/32-bit timer with complementary PWM and dead-time control), ELC for event-driven module linking without CPU intervention, DMACAa (8-channel DMA), DTCb (1-channel data transfer controller), and safety-oriented modules: S12ADH (24-channel 12-bit A/D with self-diagnosis and disconnection detection), R12DAb (2-channel 12-bit D/A), CMPC (4-channel analog comparator), and CAC for clock accuracy monitoring.

FAQ

What is the maximum operating frequency and core architecture of the R5F56609CDFB#30?

The R5F56609CDFB#30 operates at a maximum frequency of 120 MHz using the RXv3 32-bit CPU core. It delivers 709 CoreMark performance and includes a single-precision IEEE 754 floating-point unit, collective register bank save, and memory protection unit. The core supports little-endian or big-endian data arrangement and executes most instructions in a single cycle at full speed.

Does the R5F56609CDFB#30 support CAN FD, and what standard does it comply with?

Yes, the R5F56609CDFB#30 integrates one CAN FD module compliant with ISO 11898-1:2015, supporting both standard (11-bit) and extended (29-bit) frame formats. It enables high-speed data transfer up to 5 Mbps in the data phase, with built-in message filtering, FIFO buffering, and error handling - essential for modern industrial and automotive networked systems.

What package type and pin count does the R5F56609CDFB#30 use?

The R5F56609CDFB#30 uses a 144-pin Low-profile Quad Flat Package (LFQFP) with type code PLQP0144KA-B: 20 × 20 mm body, 0.5 mm lead pitch, and exposed thermal pad. This package provides 130 general-purpose I/O pins (including 4 with 5-V tolerance), JTAG and FINE debug interfaces, and full peripheral access including CAN FD, multiple SCI, RSPI, and RIIC.

How does the R5F56609CDFB#30 support IEC 60730 functional safety compliance?

The R5F56609CDFB#30 includes hardware-accelerated safety features required for Class B compliance: oscillation-stop detection, clock frequency accuracy measurement (CAC), CRC calculator (CRCA), data operation circuit (DOCA) for RAM testing, register write protection, and independent watchdog timer (IWDT) with window function. These are documented in Renesas' IEC 60730 safety manual for the RX660 Group.

What are the memory resources available on the R5F56609CDFB#30?
