Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F64165NFB#U0 | Same package and peripherals, but rated for -20°C to +85°C (N version) | Suitable for commercial indoor environments only; lacks extended low-temp operation | Select when operating ambient stays above -20°C and cost sensitivity outweighs industrial temp margin |
| R5F64165DFD#U0 | 144-pin LQFP (PLQP0144KA-A) with identical specs plus 34-channel ADC and 24 intelligent I/O outputs | Enables higher I/O density and more analog inputs - used where board space permits larger footprint | Choose when design requires >26 ADC channels or additional UART/I²C routing flexibility beyond 100-pin constraints |
Compared with R5F64165NFB#U0, the R5F64165DFB#U0 provides guaranteed operation down to -40°C for harsh industrial settings; versus R5F64165DFD#U0, it delivers identical core functionality in a smaller 100-pin footprint - optimizing PCB area and assembly cost where I/O count is sufficient.

FAQ
What is the maximum operating frequency and supply voltage range for the R5F64165DFB#U0?
The R5F64165DFB#U0 operates at a maximum frequency of 50 MHz (normal speed version) with a supply voltage range of VCC = 3.0 V to 5.5 V. It draws 35 mA at 5.0 V and 50 MHz, and supports low-power wait mode consuming just 8 µA at 3.3 V with 32.768 kHz sub-clock active. These specifications are confirmed in Renesas datasheet R01DS0063EJ0120, Tables 1.2 and 1.4.
Does the R5F64165DFB#U0 include an integrated floating-point unit, and what precision does it support?
Yes, the R5F64165DFB#U0 integrates an IEEE-754 compatible floating-point unit supporting single-precision (32-bit) arithmetic. This FPU is part of the R32C/100 Series CPU core and accelerates math-intensive tasks such as motor vector control or sensor fusion algorithms without requiring software emulation. The feature is explicitly listed in Table 1.1 under CPU section of the R01DS0063EJ0120 datasheet.
How many analog-to-digital converter channels does the R5F64165DFB#U0 support, and what is their resolution?
The R5F64165DFB#U0 supports 26 channels of 10-bit analog-to-digital conversion with integrated sample-and-hold functionality. This count applies specifically to the 100-pin variant (Table 1.4), distinct from the 34-channel capability of the 144-pin R5F64165DFD#U0. All channels share a common reference (AVCC/AVSS) and are accessible via dedicated pins P0_0–P0_7, P10_0–P10_7, and KI0–KI3 as documented in Figure 1.4 and Table 1.11.
Is the R5F64165DFB#U0 pin-compatible with other members of the R32C/116 Group, and which packages share identical pinouts?
The R5F64165DFB#U0 uses the 100-pin PLQP0100KB-A package and shares identical pinout with all other R32C/116 Group variants in that package - including R5F64165NFB#U0 and R5F64165PFB#U0. However, it is not pin-compatible with 144-pin variants (e.g., R5F64165DFD#U0) due to differing pin counts and signal allocations. Pin compatibility is confirmed in Renesas datasheet Section 1.4 and Figure 1.4.
What debug and programming interfaces are supported by the R5F64165DFB#U0 for firmware development?
The R5F64165DFB#U0 supports on-chip debug (OCD) and on-board flash programming via multiple physical interfaces - including UART channels and a dedicated debug port. No external JTAG emulator is required; development tools like Renesas E1/E20 emulators or Flash Development Toolkit (FDT) can program and debug the device in-system. This capability is detailed in Section 1.1.2 "Debugging" of the R01DS0063EJ0120 datasheet.
