ML9040 Overview
Description
The ML9040-Axx/-Bxx is a dot matrix LCD controller which is fabricated in low power CMOS silicon gate technology. Character display on the dot matrix character type LCD can be controlled in combination with a 4-bit or 8-bit microcontroller.
Key Features
- Easy interface with an 8-bit or 4-bit microcontroller
- Dot matrix LCD controller/driver for lowercase (5 x 7 dots) or uppercase (5 x 10 dots)
- Automatic power ON reset
- COMMON signal drivers (16) and SEGMENT signal drivers (40)
- Can control up to 80 characters when used in combination with MSM5259
- Character generator ROM for 160 characters with lowercase (5 x 7 dots) and 32 characters with uppercase (5 x 10 dots)
- Character patterns are programmable by character generator RAM. (Lowercase: 5 x 8 dots, 8 patterns, uppercase: 5 x 11 dots, 4 patterns)
- Built-in oscillation circuit to connect with external resistor or ceralock
- 1/8 duty (1 line; 5 x 7 dots + cursor), 1/11 duty (1 line; 5 x 10 dots + cursor), or 1/16 duty (2 lines; 5 x 7 dots + cursor), selectable
- Clear display even at 1/5 bias, 3.0V LCD driving voltage
