FAQ

What is the maximum operating frequency of the HD64F7046F50V?

The HD64F7046F50V operates at a maximum frequency of 50 MHz, determined by its internal PLL and supported by the specified 3.0–3.6 V supply range. This frequency governs instruction execution speed, timer resolution, and serial communication baud rates. The HD64F7046F50V achieves this performance while maintaining compatibility with standard 3.3 V logic families and industrial temperature ranges.

Does the HD64F7046F50V include on-chip Flash memory, and what is its capacity?

Yes, the HD64F7046F50V integrates 256 KB of on-chip Flash memory, organized as a single bank with sector erase capability. This memory stores executable code and user data, supports in-system programming via on-chip bootloader, and guarantees 100 write/erase cycles with 10-year data retention at 25°C. The HD64F7046F50V uses this Flash for both application firmware and runtime parameter storage.

How many analog input channels does the HD64F7046F50V support, and what is the ADC resolution?

The HD64F7046F50V features an 8-channel, 10-bit successive-approximation A/D converter with ±1 LSB integral nonlinearity. Channels AD0–AD7 are multiplexed onto dedicated pins and support software- or timer-triggered conversions. The HD64F7046F50V ADC includes internal sample-and-hold and reference selection (AVCC or internal bandgap), enabling precise sensor interfacing without external components.

What serial communication interfaces are integrated into the HD64F7046F50V?

The HD64F7046F50V includes three independent Serial Communication Interface (SCI) modules, each supporting both asynchronous (UART) and clock-synchronous modes. Each SCI provides full-duplex operation, programmable baud rates up to 2.5 Mbps, and status flags for transmit/receive buffer readiness and error detection. The HD64F7046F50V uses these SCIs for host communication, sensor networking, and protocol bridging in multi-interface systems.

Is the HD64F7046F50V pin-compatible with other members of the SH7046 Group?

Yes, the HD64F7046F50V shares the same 80-pin PRQP0080JD-A package and pin assignment with HD64F7045F50V and HD6437048, enabling hardware reuse across Flash and mask ROM variants. However, differences in on-chip peripherals (e.g., UBC presence, Flash size) require firmware adaptation. The HD64F7046F50V maintains identical mechanical and electrical pin behavior for all common signals including power, clocks, reset, and I/O.
