The code "D0" is non-standard but typically refers to a variant in a series. Given the context of small LCDs, this likely points to a parallel interface using the Hitachi HD44780 (or equivalent) controller. Most character LCDs with a 94V0 rating feature a 16-pin interface (or 14-pin for simple versions). The "D0" might denote the specific backlight color (e.g., White or Blue) or a specific temperature range (Standard vs. Wide). Without a genuine PHICO datasheet, one must infer the electrical characteristics: logic voltage of 5V (or 3.3V for modern variants), typical contrast adjustment via a potentiometer on pin 3 (V0), and a default character set of 5x8 dots.
