FAQ
What is the maximum operating frequency and voltage range for the R5F64166PFD#UB?
The R5F64166PFD#UB operates at up to 64 MHz with a supply voltage range of 3.0 V to 5.5 V. Its minimum instruction execution time is 15.625 ns at 64 MHz, and it supports low-power wait mode consuming just 8 µA at 3.3 V with 32.768 kHz sub-clock active. This makes the R5F64166PFD#UB suitable for both high-performance control loops and battery-backed subsystems.
Does the R5F64166PFD#UB include hardware support for three-phase motor control?
Yes, the R5F64166PFD#UB integrates a dedicated three-phase motor control timer using timers A1, A2, A4, and B2, along with an 8-bit programmable dead-time generator. This hardware block enables precise, jitter-free generation of six complementary PWM outputs with configurable dead-time - eliminating software-based timing risks in inverter gate drive circuits. The R5F64166PFD#UB uses this capability in industrial pump and HVAC blower applications.
How many analog-to-digital converter channels does the R5F64166PFD#UB support, and what is their resolution?
The R5F64166PFD#UB features a 10-bit successive-approximation A/D converter with up to 34 input channels, including dedicated AN_0 through AN_7 and AN15_0 through AN15_7 pins. Sample-and-hold functionality is integrated, enabling simultaneous sampling across multiple channels for accurate current/voltage measurement in motor control. All 34 channels are accessible in the 144-pin package used by the R5F64166PFD#UB.
Is on-chip debug supported on the R5F64166PFD#UB, and what capabilities does it provide?
Yes, the R5F64166PFD#UB includes a full on-chip debug module compliant with Renesas' standard debug interface. It supports real-time program execution control, hardware breakpoints, memory inspection, flash programming, and trace buffer capture - all without requiring external debug probes. This capability accelerates firmware validation and field diagnostics directly within the R5F64166PFD#UB target system.
What serial communication interfaces are integrated into the R5F64166PFD#UB?
The R5F64166PFD#UB integrates nine asynchronous/synchronous serial interface channels (UART0–UART8), one multi-master I²C-bus interface, and optional IEBus support. UART0–UART6 can operate in I²C-bus mode, and UART5/UART6/UART7/UART8 support variable-length synchronous serial I/O. These interfaces enable concurrent communication with displays, sensors, power ICs, and wireless modules - a key advantage of the R5F64166PFD#UB in multi-peripheral systems.
