What is the maximum operating frequency and voltage range for the R5F64169DFD#2B?
The R5F64169DFD#2B operates at a maximum frequency of 64 MHz with a supply voltage range of 3.0 V to 5.5 V. This specification applies to the D-version (-40°C to +85°C), and the device maintains full functionality across this voltage window, including flash programming and analog peripheral operation. The R5F64169DFD#2B achieves 15.625 ns minimum instruction execution time at 64 MHz under VCC = 5.0 V conditions.
Does the R5F64169DFD#2B support hardware-based three-phase motor control?
Yes, the R5F64169DFD#2B integrates a dedicated three-phase motor control timer using timers A1, A2, A4, and B2, plus an 8-bit programmable dead-time timer. This enables direct generation of complementary PWM waveforms with adjustable dead-time for inverter gate drivers, eliminating the need for external timing logic in BLDC and PMSM motor applications. The R5F64169DFD#2B also provides 34-channel 10-bit A/D conversion for current/voltage sensing.
How many serial communication interfaces does the R5F64169DFD#2B provide, and what protocols are supported?
The R5F64169DFD#2B provides nine independent serial interfaces (UART0 through UART8), each configurable for asynchronous or synchronous operation. UART0 through UART6 support I²C-bus mode, enabling standard and fast-mode (100/400 kbps) communication. Optional IEBus mode is available but requires sales office coordination. The device also includes a dedicated multi-master I²C-bus interface separate from the UART-based I²C functionality. The R5F64169DFD#2B does not integrate CAN or USB controllers.
What package type and pin count does the R5F64169DFD#2B use?
The R5F64169DFD#2B uses a 144-pin plastic molded LQFP package designated PLQP0144KA-A (also referenced as 144P6Q-A). It measures 20 mm × 20 mm with 0.5 mm lead pitch and features 120 CMOS I/O ports, of which 32 are 5 V tolerant. Pin 1 location follows the index mark per Renesas package drawings. The R5F64169DFD#2B is not offered in QFP variants with different pin counts or thermal pads.
Is on-chip debug and flash programming supported on the R5F64169DFD#2B?
Yes, the R5F64169DFD#2B includes full on-chip debug capability and on-board flash programming accessible via UART interface. This allows in-system firmware updates, real-time variable monitoring, and breakpoint-based debugging without requiring external JTAG emulators. Flash memory endurance is rated at ≥1,000 program/erase cycles, and security features include ROM code protection and ID code protection. The R5F64169DFD#2B does not require external programming hardware for development or field updates.
