Because "94V-0" is printed on millions of circuit boards worldwide, look closely at the edges of the PCB for a secondary stamped or printed part number (such as PHICO SS-M , 1074 , 1620 , or similar alphanumeric strings) to pinpoint the exact display variant. Common Architecture: The HD44780 Standard
These modules display fixed-sized text characters across designated rows and columns. They almost universally utilize the industry-standard controller (or an equivalent clone like the ST7066). Interface: 4-bit or 8-bit parallel bus.
PHICO D0 94V0 LCD Display: Datasheet and Specifications Guide
Because this module adheres to the HD44780 standard parallel interface, it uses a standard 16-pin header (or 14-pin if no backlight). This makes it compatible with Arduino, PIC, and STM32 microcontrollers.
The PHICO D0 94V0 marking on a circuit board is a frequent sight for electronics hobbyists, repair technicians, and hardware engineers. If you are searching for the datasheet for this specific component, understanding what this alphanumeric string actually represents will drastically simplify your documentation search. phico d0 94v0 lcd display datasheet pdf

The term typically refers to a specific series of Character LCD Modules manufactured by Phico (Phico Technology Co., Ltd.) .
This comprehensive guide compiles the structural, electrical, and pinout information required to interface with or replace a Phico D0 94V0 LCD module. Deconstructing the "Phico D0 94V0" Label
The standard footprint of the Phico D-0 architecture balances space efficiency with optimal outdoor or industrial scannability. The character-based systems (like the 16x1 character layout) adhere to the following physical geometry: 80.0 mm × 36.0 mm × 10.0 mm Active Viewing Area: 65.0 mm × 14.0 mm Dot Size: 0.55 mm × 0.75 mm Dot Pitch: 0.63 mm × 0.83 mm Safety Rating: UL 94V-0 certified flame resistance Standard Pinout Configuration (16-Pin Interface) Because "94V-0" is printed on millions of circuit

How to Interface the Phico LCD
If you have wired your PHICO D0 94V0 module and it is not behaving correctly, evaluate it against these common vintage hardware failure modes:
Typically optimized for 6 o'clock or 12 o'clock viewing directions. Operating Voltage ( VDDcap V sub cap D cap D end-sub ): Standard ) for legacy systems; newer revisions may support low-power logic. LCD Driving Voltage ( VOcap V sub cap O Interface: 4-bit or 8-bit parallel bus
The "PHICO D0 94V0 LCD Display" is a phantom product that exists physically but not in formal documentation. The string "94V0" is the only technical guarantee, certifying the PCB as flame-retardant. The "D0" likely signifies a minor mechanical variant of a standard HD44780-compatible character LCD. While a dedicated datasheet for "PHICO" cannot be produced, the device can be successfully driven using generic LCD library examples for Arduino or PIC microcontrollers. Ultimately, this query demonstrates that for generic displays, the UL safety rating on the PCB is often more reliable than the missing brand name on the label.
In terms of hardware interface, a Phico D0 series module usually features a 14-pin or 16-pin header. Pins 1 through 6 handle power and control signals—specifically Ground, VCC (usually 5V), Contrast Adjustment (V0), Register Select (RS), Read/Write (RW), and Enable (E). Pins 7 through 14 comprise the 8-bit data bus. If the module has 16 pins, the final two pins are dedicated to the LED backlight anode and cathode.
