FAQ
What is the maximum operating frequency and instruction timing of the R5F64189HDFD#2A?
The R5F64189HDFD#2A operates at a maximum frequency of 64 MHz, achieving a minimum instruction execution time of 15.625 ns. This timing is guaranteed under VCC = 3.0 to 5.5 V and -40°C to +85°C conditions. The R5F64189HDFD#2A uses the R32C/100 Series CPU core with optimized pipeline and on-chip cache to sustain this performance in real-world code execution.
Does the R5F64189HDFD#2A support CAN FD or only classical CAN 2.0B?
The R5F64189HDFD#2A supports only ISO 11898-1 compliant classical CAN 2.0B - not CAN FD. Its dual CAN modules provide 32 mailboxes, hardware acceptance filtering, and bit rates up to 1 Mbps. CAN FD capability is absent per the R32C/118 Group datasheet R01DS0065EJ0120 Rev.1.20, and no firmware or configuration option enables FD framing.
How many analog-to-digital converter channels does the R5F64189HDFD#2A include, and what is their resolution?
The R5F64189HDFD#2A integrates a 10-bit successive-approximation ADC with 34 input channels. All channels feature built-in sample-and-hold functionality. This count applies specifically to the 144-pin package variant; the 100-pin version offers 26 channels. The R5F64189HDFD#2A's ADC supports simultaneous sampling across multiple channels using internal trigger sources.
What debug and programming interfaces are available on the R5F64189HDFD#2A?
The R5F64189HDFD#2A includes an on-chip debug interface compliant with Renesas E1/E20 standards, supporting full JTAG-based debugging, real-time trace, and flash memory programming. No external debug probe is required for basic firmware load and breakpoint operation. The R5F64189HDFD#2A also supports on-board flash programming via UART or CAN, enabling field firmware updates without physical access to debug headers.
Is the R5F64189HDFD#2A pin-compatible with other members of the R32C/118 Group?
Yes - the R5F64189HDFD#2A shares identical pinout and electrical characteristics with all other 144-pin LQFP variants in the R32C/118 Group (e.g., R5F64185HDFD#2A, R5F64188HDFD#2A). Pin compatibility extends across flash size, RAM size, and temperature grade within the same package type, allowing drop-in replacement during design iteration or qualification testing of the R5F64189HDFD#2A.
