FAQ
What is the maximum operating frequency of the DF61664W50FPV?
The DF61664W50FPV is rated for a maximum system clock frequency of 50 MHz under specified 3.3 V supply and industrial temperature conditions. This frequency is supported across the full operating voltage range (3.0 V to 3.6 V) and enables sub-microsecond interrupt latency and tight control loop timing for motor and power conversion applications. The DF61664W50FPV achieves this using an on-chip PLL that multiplies an external 1–20 MHz reference clock.
Does the DF61664W50FPV include built-in CAN physical layer drivers?
No, the DF61664W50FPV integrates a CAN 2.0B protocol controller but does not include physical layer (PHY) drivers. It provides dedicated CANTX and CANRX signal pins that must interface with an external ISO 11898-compliant CAN transceiver, such as the TJA1042 or SN65HVD230. This separation allows design flexibility in bus termination, ESD protection, and fault handling while maintaining DF61664W50FPV's qualification for industrial environments.
What package type and pin count does the DF61664W50FPV use?
The DF61664W50FPV uses a 128-pin LQFP (Low-Profile Quad Flat Package) with 0.5 mm lead pitch and 14 mm × 14 mm body size. This package is RoHS-compliant, reflow-solderable per JEDEC J-STD-020, and includes an exposed thermal pad for improved heat dissipation during sustained 50 MHz operation. Pin assignments match the H8SX/1664 Group standard layout documented in Renesas Hardware Manual REJ09B0073.
Is the DF61664W50FPV qualified for automotive applications?
No, the DF61664W50FPV is classified as a "Standard" quality grade device per Renesas' product grading system and is intended for industrial applications such as motor drives, PLCs, and building automation-not automotive or safety-critical transportation systems. It meets AEC-Q100 stress testing only if explicitly validated in a customer-specific qualification program; Renesas does not certify DF61664W50FPV for automotive use out-of-box.
Does the DF61664W50FPV support in-system programming via its serial interfaces?
Yes, the DF61664W50FPV supports in-system programming (ISP) through its SCI0 interface using Renesas' Flash Development Toolkit (FDT) and a standard UART bootloader. The on-chip Flash memory can be erased and reprogrammed in blocks or sectors without removing the DF61664W50FPV from the target board, enabling field firmware updates and manufacturing programming. ISP requires the RESET pin to be held low during boot and a valid baud rate configuration matching the host tool.
