FAQ

What is the maximum operating frequency of the DF2318VTE25V?

The DF2318VTE25V operates at a maximum frequency of 25 MHz. This clock speed is specified under standard industrial temperature and voltage conditions (VCC = 4.5–5.5 V, TA = –20 to +75°C) and determines the upper limit for instruction execution rate, peripheral timing, and serial communication baud rates. The DF2318VTE25V achieves this using an external crystal oscillator connected to XTAL/EXTAL pins, with internal PLL circuitry ensuring stable core timing.

Does the DF2318VTE25V include on-chip flash memory, and what are its endurance specifications?

Yes, the DF2318VTE25V integrates 256 KB of on-chip F-ZTAT™ flash memory. Its endurance is rated for a minimum of 100 erase/write cycles, with data retention guaranteed for at least 10 years at 25°C. Programming time is 10–200 ms per 128-byte block, and erase time is 50–1000 ms per block. These values are measured under standard operating conditions and documented in the H8S/2319 Group Hardware Manual Rev.7.00.

How many analog-to-digital input channels does the DF2318VTE25V support, and what is its resolution?

The DF2318VTE25V supports 12 analog input channels with 10-bit resolution. Each channel is mapped to dedicated pins (AD0–AD11) and shares physical connections with Port A pins, requiring proper mode configuration. Conversion time is 1.2 μs, enabling sampling rates up to ~833 kSPS in burst mode. The A/D converter includes built-in sample-and-hold and supports software/start-triggered conversion sequences.

What serial communication interfaces are integrated into the DF2318VTE25V?

The DF2318VTE25V integrates two full-duplex Serial Communication Interfaces (SCI) compliant with asynchronous serial protocols (e.g., RS-232, RS-485). Each SCI supports programmable baud rates up to 31.25 kbps when operating at 25 MHz, with configurable stop bits, parity, and data length. Both interfaces feature separate transmit and receive shift registers, status flags, and interrupt capability for efficient background data handling.

What package type and pin count does the DF2318VTE25V use?

The DF2318VTE25V is packaged in a 113-pin LQFP (Low-Profile Quad Flat Package) with 16 mm × 16 mm body size and 0.5 mm lead pitch. This package supports fine-pitch PCB assembly and provides dedicated power/ground pins for analog and digital domains, along with multiplexed I/O for flexible board layout. Pin assignments match the H8S/2319 Group standard layout defined in the Hardware Manual Rev.7.00.
