FAQ
What is the maximum operating frequency of the R5F64169PFB#UB?
The R5F64169PFB#UB is a normal-speed version rated for 50 MHz operation at VCC = 3.0 to 5.5 V. Its CPU core achieves a minimum instruction execution time of 20 ns at this frequency, enabling deterministic real-time performance for industrial control loops and communication stacks. The same silicon can operate up to 64 MHz in high-speed variants (e.g., R5F64169HNFB#UB), but R5F64169PFB#UB is factory-configured for 50 MHz.
Does the R5F64169PFB#UB include an integrated debug interface?
Yes, the R5F64169PFB#UB features an on-chip debug interface compliant with Renesas E1/E20 standards, supporting full hardware debugging, flash programming, and real-time trace without external emulators. This interface operates over dedicated pins (e.g., TDI/TDO) and is fully accessible via standard Renesas toolchains, enabling rapid firmware development and field updates directly to the R5F64169PFB#UB's internal flash memory.
How many analog-to-digital converter channels does the R5F64169PFB#UB support?
The R5F64169PFB#UB integrates a 10-bit successive-approximation A/D converter with 26 input channels, as confirmed for the 100-pin package variant. These channels include dedicated pins (P10_0–P10_7, P0_0–P0_7, P9_6/P9_7, and ANEX0/ANEX1) and support sample-and-hold functionality for accurate simultaneous sampling across multiple sensors in industrial monitoring applications.
Is the R5F64169PFB#UB pin-compatible with other R32C/116 Group MCUs?
Yes, all R32C/116 Group devices in the same package variant - including R5F64165PFB#UB, R5F64166PFB#UB, R5F64167PFB#UB, R5F64168PFB#UB, and R5F64169PFB#UB - share identical 100-pin LQFP (PLQP0100KB-A) pinouts and peripheral mappings. This allows hardware reuse across product tiers, where only flash size (384 KB to 1 MB) and RAM (40–63 KB) differ, simplifying platform scalability and reducing PCB redesign effort.
What serial communication protocols are supported by the R5F64169PFB#UB?
The R5F64169PFB#UB supports nine asynchronous/synchronous serial interfaces (UART0–UART8), configurable for UART, I²C-bus (on UART0–UART6), and optional IEBus (UART0–UART6). It also includes a dedicated multi-master I²C-bus interface, enabling concurrent communication with sensors, displays, and other peripherals without resource contention. All UARTs support full-duplex operation, programmable baud rates, and hardware flow control (CTS/RTS).
