Phico D0 94v0 Lcd Display Datasheet Pdf Jun 2026

Because these modules use standard HD44780 controller logic, interfacing them with a modern microcontroller like an Arduino, ESP32, or STM32 is simple. The display can operate in either (utilizing all data pins DB0-DB7) or 4-bit mode (utilizing only pins DB4-DB7), which saves valuable I/O pins on your controller. 4-Bit Hardware Interfacing Diagram

Operating these legacy displays in a modern context requires careful attention to the contrast voltage. While the logic typically runs at 5V, the contrast pin often requires a variable voltage between 0V and 5V, usually managed via a 10k-ohm potentiometer. Without this precise adjustment, the display will either appear entirely blank or show solid "blocks" in the character cells, leading many hobbyists to believe the unit is defective when it is simply misconfigured.

The (often branded as Data Vision ) refers to a series of LCD modules rather than a single specific component. The "94V-0" designation is actually a UL flammability rating for the PCB material, while "D-0" is a common series identifier for modules manufactured by PHICO, a Taiwanese PCB manufacturer that supplies boards for various display brands. General Technical Specifications phico d0 94v0 lcd display datasheet pdf

The PHICO D0 94V0 LCD display is a high-quality display module designed for use in various electronic devices. It features a high-resolution LCD panel with a wide viewing angle, making it ideal for applications where image quality is crucial. The display is manufactured by PHICO, a reputable company known for producing high-quality display modules.

If your PHICO D0 94V0 module features a single row of 14 or 16 pins (or pads), it follows this standard layout: Pin Number Technical Description VSScap V sub cap S cap S end-sub 0V System Reference 2 VDDcap V sub cap D cap D end-sub Power Supply Typically +5.0V (some modern variants use +3.3V) 3 VOcap V sub cap O VEEcap V sub cap E cap E end-sub Contrast Adjust Variable voltage via a 10k Ωcap omega potentiometer 4 Register Select Low = Instruction Register; High = Data Register 5 Read / Write Low = Write to LCD; High = Read from LCD 6 Falling-edge triggered signal to latch data 7 – 14 DB0 – DB7 Because these modules use standard HD44780 controller logic,

While "D0 94V0" often appears on the PCB silkscreen or label, it is not always the full model number. These modules are standard commonly used in industrial control panels, amateur radio equipment, and consumer electronics.

While specific models vary, Phico character LCDs built on the 94V-0 rated boards generally share the following baseline specifications: Electrical Characteristics Operating Voltage ( VDDcap V sub cap D cap D end-sub While the logic typically runs at 5V, the

Note: Older or specialized modules might omit Pins 15 and 16 if they lack an integrated LED backlight. Electrical Characteristics and Maximum Ratings

Standard PHICO character LCDs utilize a 14-pin or 16-pin interface header. The 16-pin variant simply adds two dedicated connections for an integrated LED backlight.

100 mA to 240 mA typical. Note: Always use a current-limiting resistor (e.g., 47 Ωcap omega Ωcap omega ) on Pin 15 to prevent burning out the backlight. Interfacing with Modern Microcontrollers

Based on common Data Vision Phico implementations (such as the DV-16100 series), the technical specifications are typically as follows: Character LCD (16 characters x 2 lines). Module Dimensions: Approx. Viewing Area: Dot Size: Dot Pitch: Controller IC: HD44780 compatible (or equivalent). Operating Voltage: Supply Current: Operating Temperature: 0∘C0 raised to the composed with power C 50∘C50 raised to the composed with power C Display Color: Usually Yellow-Green (STN) or Blue. 2.
