FAQ
What is the maximum operating frequency and voltage range for the R5F64165PFD#UB?
The R5F64165PFD#UB operates at up to 64 MHz with a supply voltage range of 3.0 V to 5.5 V. It achieves a minimum instruction execution time of 15.625 ns at 64 MHz and supports low-power wait mode consuming only 8 µA at 3.3 V with 32.768 kHz sub-clock active. This makes the R5F64165PFD#UB suitable for both high-speed control loops and battery-backed standby functions.
Does the R5F64165PFD#UB include hardware debugging support?
Yes, the R5F64165PFD#UB includes on-chip debug capability compatible with Renesas E1/E20 emulators and supports on-board flash programming. Debug access uses dedicated pins (XIN/XOUT, RESET, and optional trace ports) and does not require sacrificing user I/O. The R5F64165PFD#UB also supports ROM code protection and ID code protection to prevent unauthorized firmware extraction during development or field deployment.
How many UART channels does the R5F64165PFD#UB support, and which ones implement I²C functionality?
The R5F64165PFD#UB supports nine UART channels (UART0 through UART8). UART0 to UART6 each provide configurable I²C-bus interface functionality via shared pins (e.g., SCL2/SDA2 on UART2), enabling multi-master I²C operation without dedicated hardware blocks. UART7 and UART8 operate in standard asynchronous/synchronous mode only and do not support I²C. This architecture allows flexible allocation of serial resources across mixed-protocol systems.
What ADC resolution and channel count does the R5F64165PFD#UB provide, and are sample-and-hold circuits integrated?
The R5F64165PFD#UB integrates a 10-bit successive-approximation ADC with 34 input channels in the 144-pin package. Sample-and-hold circuitry is built into the ADC front-end, enabling accurate conversion of fast-changing analog signals such as motor phase currents. Input channels include dedicated AN_0–AN_7, AN0_0–AN0_7, AN2_0–AN2_7, AN15_0–AN15_7, and ANEX0/ANEX1 - all accessible without external signal conditioning for typical industrial sensor ranges.
Is the R5F64165PFD#UB pin-compatible with other members of the R32C/116 Group, such as the R5F64167PFD#UB?
Yes, the R5F64165PFD#UB is pin-compatible with all 144-pin R32C/116 Group variants including R5F64167PFD#UB and R5F64168PFD#UB. They share identical PLQP0144KA-A packaging, pin assignments, peripheral mappings, and electrical characteristics - differing only in flash size (384 KB vs. 640 KB vs. 768 KB), RAM capacity (40 KB vs. 48 KB vs. 63 KB), and associated part numbering. This allows direct hardware reuse across product tiers with only firmware and BOM updates required.
