8-bit parallel with dedicated chip select lines for different display segments.
Most character-based PHICO modules integrate a Hitachi HD44780-compatible dot-matrix LCD controller or an equivalent Sitronix/Samsung driver IC. This ensures universal compatibility with modern microcontroller architectures, allowing engineers to drop these legacy modules into modern hardware designs using standard code libraries.

Search for industry equivalents using the form factor (e.g., standard 1602 LCD module dimensions). Because these panels comply with strict industrial standards, alternative parts from manufacturers like Sunlike, Optrex, or Winstar often share identical footprint dimensions, command structures, and pinouts.
This is an Underwriters Laboratories (UL) flame retardant rating. It guarantees that the device will self-extinguish within 10 seconds during a fire test. It is not a model number. 8-bit parallel with dedicated chip select lines for
Connect Phico to Arduino Digital Pins 5, 4, 3, 2 respectively.
Based on standard 94V0-rated displays, the "PHICO D0" likely measures 80mm x 36mm for a 16x2 character layout. The datasheet (if it existed) would show a standard pinout: Pin 1 (Vss/Ground), Pin 2 (Vdd/+5V), Pin 3 (V0/Contrast), Pin 4 (RS), Pin 5 (R/W), Pin 6 (E), and Pins 7-14 (DB0-DB7). The "94V0" rating suggests the module operates between 0°C and 50°C. A missing datasheet forces the user to reverse-engineer these parameters, often by treating the device as a "standard HD44780 clone," which is a safe assumption for 99% of generic LCDs. Interface Pinout Configurations ): +5
Ground Pin 1 and Pin 5 to common system ground to set the unit permanently to . Power Pin 2 with +5V from your developer board.
Note: Older or specialized modules might omit Pins 15 and 16 if they lack an integrated LED backlight. Electrical Characteristics and Maximum Ratings
To locate the correct datasheet PDF for a PHICO display bearing the 94V-0 mark, you must locate the specific alphanumeric model number (usually formatted as something like PHICO D-0 followed by a series of numbers, or M-0 , or similar proprietary designations) etched onto the copper traces or printed via a white silkscreen label on the board.
