It delivers 709 CoreMark performance and includes a single-precision IEEE 754 floating-point unit, 113 instructions, and a collective register bank save function with 16 banks. The R5F56609BDFB#30 supports little-endian or big-endian data arrangement and executes most instructions in one system clock cycle.

Does the R5F56609BDFB#30 support CAN FD, and what standard does it comply with?

Yes, the R5F56609BDFB#30 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. The R5F56609BDFB#30 provides dedicated CTX0/CRX0 pins and hardware message filtering, FIFO buffering, and error handling without CPU overhead.

What analog peripherals are included in the R5F56609BDFB#30, and how many channels do they support?

The R5F56609BDFB#30 includes a 24-channel 12-bit S12ADH analog-to-digital converter with 0.9 µs minimum conversion time, two 12-bit R12DAb digital-to-analog converters, four-channel CMPC analog comparators, and an on-die temperature sensor with ±1.0°C relative precision. All analog modules are directly accessible via dedicated pins and support event linking via ELC for synchronized operation - critical for motor control and sensor fusion in the R5F56609BDFB#30.

What package type and pin count does the R5F56609BDFB#30 use, and is it RoHS compliant?
