FAQ

What is the maximum operating frequency of the DF2667VFQ33V?

The DF2667VFQ33V operates at a maximum frequency of 33 MHz, achieved using an external crystal (1–20 MHz) multiplied by the on-chip PLL circuit. This speed enables sub-microsecond interrupt response and supports real-time control tasks such as motor commutation and closed-loop feedback processing. The DF2667VFQ33V's timing specifications are fully characterized across its commercial temperature range (0°C to +70°C) and 3.3 V ±0.3 V supply.

Does the DF2667VFQ33V include on-chip flash memory, and is it reprogrammable?

Yes, the DF2667VFQ33V integrates 512 KB of F-ZTAT™ (Flash Zero Turnaround Access Time) flash memory, which supports in-system programming without UV erasure or external programmers. This allows firmware updates in the field or during production testing. The DF2667VFQ33V's flash endurance is rated for 100–10,000 write/erase cycles with 10-year data retention, as specified in Renesas' Hardware Manual Rev. 3.00.

Which analog peripherals are integrated into the DF2667VFQ33V?

The DF2667VFQ33V integrates a 10-bit successive-approximation A/D converter with up to 16 input channels and an 8-bit D/A converter with four output channels. These are powered from a dedicated analog supply (AVCC/AVSS) and share pins with IRQ and port functions (e.g., P50–P57). The DF2667VFQ33V's A/D supports software/start-triggered conversion with interrupt notification upon completion, enabling precise sensor data acquisition in noise-sensitive environments.

What communication interfaces does the DF2667VFQ33V support?

The DF2667VFQ33V supports two full-duplex Serial Communication Interfaces (SCI0 and SCI1), each configurable for UART, IrDA physical layer, or ISO/IEC 7816 Smart Card mode. It also includes a Data Transfer Controller (DTC) that can autonomously move data between peripherals and memory without CPU intervention. These interfaces make the DF2667VFQ33V suitable for industrial telemetry, medical device diagnostics, and secure element interfacing - all within a single chip.

Is the DF2667VFQ33V pin-compatible with other H8S/2667 variants?

Yes, the DF2667VFQ33V shares the same 128-pin LQFP package and pin assignment with other members of the H8S/2667 F-ZTAT™ family, including the HD64F2667FV and R5F2667CDFP. Pin functions - including power, clock, reset, address/data bus, and peripheral I/O - are identical across these variants. This allows direct substitution in existing PCB layouts when migrating between flash and mask-ROM versions or updating part nomenclature post-Renesas merger.
