FAQ

What is the maximum operating frequency of the R5F61662N50FPV?

The R5F61662N50FPV operates at a maximum CPU clock frequency of 50 MHz, achieved via its internal PLL with selectable multiplication factors. This frequency is validated across the full industrial temperature range (−40°C to +85°C) and 3.0 V to 3.6 V supply, enabling deterministic execution of real-time control loops in applications such as servo drives and programmable logic controllers. The R5F61662N50FPV achieves 50 MIPS throughput at this speed.

Does the R5F61662N50FPV include on-chip Flash memory, and what is its capacity?

Yes, the R5F61662N50FPV integrates 256 KB of on-chip Flash memory for program storage and data retention. This Flash supports block erase, byte/word programming, and read-while-write capability - allowing firmware updates without halting real-time operations. The memory is rated for ≥10,000 write/erase cycles and retains data for 20 years at 85°C, making it suitable for field-deployed industrial controllers where reliability and longevity are critical. The R5F61662N50FPV uses this Flash for both boot code and application firmware.

What communication interfaces are supported by the R5F61662N50FPV?

The R5F61662N50FPV supports three Serial Communications Interface (SCI) modules operating in UART mode, plus one I²C-compatible interface. Each SCI includes independent baud-rate generators, FIFO buffers, and framing error detection - enabling robust RS-232/RS-485 connectivity for HMI, diagnostics, or fieldbus bridging. The I²C interface supports standard and fast-mode speeds (up to 400 kbps) for connecting sensors, EEPROMs, or display controllers. No CAN or USB interfaces are integrated in the R5F61662N50FPV.

What is the package type and pin count of the R5F61662N50FPV?

The R5F61662N50FPV is housed in a 144-pin LQFP package (suffix FPV), measuring 20 mm × 20 mm with 0.5 mm lead pitch. It includes an exposed thermal pad on the underside for enhanced heat dissipation in high-duty-cycle applications. Pin assignments are fully documented in the H8SX/1665 Group Hardware Manual Rev. 2.00, and the package is RoHS-compliant and lead-free. The R5F61662N50FPV shares this package with other members of the H8SX/1662 family for board-level compatibility.

Is the R5F61662N50FPV suitable for automotive applications?

No, the R5F61662N50FPV is classified as a Standard-grade Renesas product intended for industrial applications such as factory automation, office equipment, and test instrumentation - not for automotive use. It does not meet AEC-Q100 qualification requirements, lacks extended temperature range (−40°C to +125°C), and has no built-in fault-tolerant features required for automotive ECUs. For automotive-grade alternatives, Renesas offers RH850 or RL78 families. The R5F61662N50FPV is explicitly rated for −40°C to +85°C operation only.
