LC75816W
Overview
The LC75816E and LC75816W are 1/8 to 1/10 duty dot matrix LCD display controllers/drivers that support the display of characters, numbers, and symbols. In addition to generating dot matrix LCD drive signals based on data transferred serially from a microcontroller, the LC75816E and LC75816W also provide on-chip character display ROM and RAM to allow display systems to be implemented easily. These products also provide up to 2 general-purpose output ports and incorporate a key scan circuit that accepts input from up to 30 keys to reduce printed circuit board wiring.
Features
- Key input function for up to 30 keys (A key scan is performed only when a key is pressed.)
- Controls and drives a 5 × 7, 5 × 8, or 5 × 9 dot matrix LCD.
- Supports accessory display segment drive (up to 65 segments)
- Display technique: 1/8 duty 1/4 bias drive (5 × 7 dots) 1/9 duty 1/4 bias drive (5 × 8 dots) 1/10 duty 1/4 bias drive (5 × 9 dots)
- Display digits: 13 digits × 1 line (5 × 7 dots) 12...
