This is not a model number . It is a flammability rating established by Underwriters Laboratories (UL 94). A "94V-0" rating signifies that the plastic/fiberglass PCB materials are self-extinguishing within 10 seconds during vertical flame testing.

Once you confirm your LCD works as a generic HD44780 display, you don't need a part-specific datasheet. Instead, use the generic datasheet for the (or compatible controllers like Samsung KS0066U) for all low-level timing and instruction set details. You can search for "HD44780 datasheet" or "KS0066U datasheet" online.
The PHICO D0 94V0 datasheet PDF is a comprehensive document that provides detailed information about the display module's characteristics, performance, and functionality. The datasheet typically includes the following sections:
Because "Phico D-0" is used across various displays, identify your specific unit by the secondary sticker or printed code: Go to product viewer dialog for this item. : 16 characters : 16 characters 2 lines (common in industrial equipment like fax machines).
Connect Phico to Arduino Digital Pins 5, 4, 3, 2 respectively.
