Overview
R5F64168PFB#UB from Renesas Electronics is a 768 KB flash, 63 KB RAM, 100-pin LQFP microcontroller in the R32C/116 Group, featuring a 32-bit CISC CPU core with IEEE-754 single-precision FPU, 9-channel UART/serial interface (including I²C-bus), 10-bit 26-channel A/D converter, and three-phase motor control timer - deployed in industrial printers and office equipment.
For engineers reviewing the R5F64168PFB#UB datasheet, R5F64168PFB#UB pinout, R5F64168PFB#UB application, or R5F64168PFB#UB equivalent, key selection criteria include operating temperature range (−40°C to +85°C), 50 MHz CPU frequency, 100-pin PLQP0100KB-A package compatibility, and integrated DMAC with 51 request sources for deterministic peripheral data movement.
Technical Context
The R5F64168PFB#UB implements the R32C/100 Series CPU core with 108 basic instructions, 15.625 ns minimum instruction execution time at 64 MHz (though this part is rated for 50 MHz), and hardware multiplier/multiply-accumulate units supporting 32×32→64-bit operations. Its memory architecture provides 4 GB address space with up to 64 MB user-accessible external bus expansion.
It integrates dual DMA controllers: a 4-channel DMAC with cycle-steal transfer and 51 request sources, plus DMAC II triggered by any peripheral interrupt, enabling immediate data transfer, calculation result transfer, and chain transfer - critical for real-time motor control and sensor acquisition pipelines.

FAQ
What is the maximum operating frequency of the R5F64168PFB#UB?
The R5F64168PFB#UB is rated for a maximum operating frequency of 50 MHz at VCC = 3.0 to 5.5 V. This corresponds to a minimum instruction execution time of 20 ns. While the R32C/100 Series CPU core supports up to 64 MHz in high-speed variants (denoted by 'H' in part number), the R5F64168PFB#UB is the normal-speed version without the 'H' suffix.
Does the R5F64168PFB#UB include an integrated debug interface?
Yes, the R5F64168PFB#UB features an on-chip debug interface compliant with Renesas E1/E20 standards. It supports full break/trace functionality, flash programming, and real-time variable monitoring without requiring external debug probes - enabling rapid development and field firmware updates directly through the R5F64168PFB#UB's dedicated debug pins.
How many A/D converter channels does the R5F64168PFB#UB support?
The R5F64168PFB#UB supports 26 channels of 10-bit A/D conversion with integrated sample-and-hold circuitry. This is confirmed for the 100-pin package variant (PLQP0100KB-A) per Table 1.4 and Figure 1.4. The 144-pin variants support up to 34 channels, but the R5F64168PFB#UB is specifically the 100-pin configuration.
What serial communication interfaces are integrated into the R5F64168PFB#UB?
The R5F64168PFB#UB integrates nine asynchronous/synchronous serial interface channels (UART0–UART8), with UART0–UART6 supporting I²C-bus mode, Special Mode 2, and optional IEBus. It also includes one dedicated multi-master I²C-bus interface. No CAN, LIN, or USB interfaces are present - communication relies on UART-derived protocols and external transceivers.
Is the R5F64168PFB#UB pin-compatible with other R32C/116 Group devices?
Yes, the R5F64168PFB#UB shares identical pinout and electrical characteristics with all other 100-pin R32C/116 Group MCUs (e.g., R5F64165PFB#UB, R5F64166PFB#UB) in the PLQP0100KB-A package. Memory size, A/D channel count, and peripheral enablement vary by part number, but PCB layout and signal routing remain fully interchangeable within the 100-pin family.
