FAQ

What is the maximum operating frequency of the R5F61663MN50FPV?

The R5F61663MN50FPV supports a maximum CPU clock frequency of 50 MHz, achieved using the on-chip PLL with an external 8 MHz crystal. This frequency is validated across the full industrial temperature range (−40°C to +85°C) and supply voltage (3.0–3.6 V), as specified in the H8SX/1668R and H8SX/1668M Hardware Manual Rev. 2.00. The R5F61663MN50FPV maintains timing compliance without derating under these conditions.

Does the R5F61663MN50FPV include hardware debug support?

Yes, the R5F61663MN50FPV integrates an on-chip debugging interface compliant with Renesas E1/E20 emulators. It supports full breakpoint, watchpoint, and real-time trace capabilities via dedicated debug pins (BKIN, BKOUT), enabling non-intrusive firmware validation without requiring external JTAG adapters. This capability is documented in Section 5.3 of the Hardware Manual for the H8SX/1663M Group.

What is the Flash memory endurance specification for the R5F61663MN50FPV?

The R5F61663MN50FPV guarantees 10,000 write/erase cycles for its 256 KB on-chip Flash memory, with data retention exceeding 20 years at +85°C. Each 2 KB block can be erased independently, allowing field firmware updates without erasing the entire memory. These values are specified in the Electrical Characteristics section of the official Renesas datasheet for the H8SX/1663M Group.

Can the R5F61663MN50FPV operate from a single 3.3 V supply?

Yes, the R5F61663MN50FPV operates from a single 3.3 V nominal supply within the validated range of 3.0 V to 3.6 V. All I/O pins are 3.3 V tolerant, and internal regulators generate required core voltages - no external voltage translation is needed for interfacing with standard 3.3 V logic peripherals. This is confirmed in Table 5.1 (DC Characteristics) of the Hardware Manual Rev. 2.00.

Is the R5F61663MN50FPV pin-compatible with other H8SX/1663x variants?

Yes, the R5F61663MN50FPV shares identical LQFP-100 pinout and signal mapping with R5F61663R, R5F61663M, and R5F61664M variants in the same family. Pin compatibility extends to power, reset, clock, and all peripheral I/O assignments - enabling hardware reuse across performance tiers. This is explicitly confirmed in Section 1.4 (Pin Assignments) of the H8SX/1668R and H8SX/1668M Hardware Manual.
