FAQ
What is the maximum operating frequency of the DF61664N50FPV?
The DF61664N50FPV operates at a maximum frequency of 40 MHz, achieved via its on-chip PLL driven by an external crystal (1–20 MHz) or clock source. This frequency is fully supported across the specified industrial temperature range (−40°C to +85°C) and 3.3 V ±10% supply voltage, enabling deterministic execution of real-time control algorithms without throttling.
Does the DF61664N50FPV include CAN interface capability?
Yes, the DF61664N50FPV integrates two independent CAN 2.0B controllers supporting both standard (11-bit) and extended (29-bit) identifier formats. Each controller has dedicated TX/RX pins (CAN0TX/CAN0RX and CAN1TX/CAN1RX), and both support bit rates up to 1 Mbps. External CAN transceivers are required for physical layer connection.
What is the Flash and RAM capacity of the DF61664N50FPV?
The DF61664N50FPV includes 512 KB of on-chip Flash memory for program storage and 32 KB of SRAM for runtime data. The Flash supports in-system programming (ISP) and is organized to allow sector erase and byte/word programming. The RAM is unified and accessible at full CPU speed without wait states.
Is the DF61664N50FPV pin-compatible with other H8SX/166x devices?
The DF61664N50FPV shares the same 128-pin LQFP package and pin assignment with the R5F61664N50FPV and R5F61663N50FPV. However, R5F61663N50FPV omits CAN1 and reduces Flash size; thus, while footprint-compatible, full functional pin compatibility requires verification of peripheral enablement in target software and hardware design.
What debug interface does the DF61664N50FPV support?
The DF61664N50FPV supports JTAG-based on-chip debugging per IEEE 1149.1, enabling full visibility into CPU registers, memory, and peripheral states during development. It supports hardware breakpoints, watchpoints, and real-time trace via the on-chip debug module - eliminating need for external emulators in most embedded firmware validation workflows.
