ACM1602E-FL-YBS is a 16×2 character LCD module designed for embedded systems and display applications requiring alphanumeric output. The module features a 1/16 duty cycle with 0.56mm × 0.61mm dot size and 0.61mm × 0.66mm dot pitch, controlled by a SPLC780D or equivalent controller IC. It operates at +5V with a standard temperature range of 0°C to 50°C, and supports both TN and STN liquid crystal fluid options with LED backlight capability. The module measures 85.0mm (W) × 36.0mm (H) × 13.5mm (D) maximum for the LED backlight version, with a 16-pin parallel interface including 8-bit data bus, control signals (RS, R/W, E), and dedicated backlight power pins. This LCD module is ideal for industrial equipment, consumer electronics, instrumentation panels, and any application requiring compact, reliable character display with straightforward microcontroller integration.
