LC7982A

www.DataSheet4U.com Ordering number : EN5946 CMOS IC LC7982A LCD Dot Matrix Graphics Display Controller Overview The LC7982A is an LCD dot matrix graphics display controller IC. It stores display data sent from an 8-bit microcontroller in external display RAM and generates dot matrix LCD drive signals. Applications can select either of two modes: graphics mode, in which each bit in external RAM controls the on/off state of an individual pixel (dot) on the LCD, and character mode, in which character codes are stored in external RAM and the dot pattern is generated using the built-in character generator ROM. Thus the LC7982A can support a wide range of applications. The LC7982A is fabricated in a CMOS process, and in conjunction with a CMOS microcontroller, can implement low-power LCD display systems. This device differs from the LC7981 only in the data stored in the built-in character generator ROM. Extensive set of command functions — Scroll, cursor on/off/blink, character blinking, bit manipulation Display methods : Method A and method B (program selectable) Built-in oscillator circuit (Using an external resistor and capacitor) Low power +5V single-voltage power supply Package Dimensions unit: mm 3055A-QFP60C [LC7982A] Features LCD dot matrix and graphics display controller Display control capacity Graphics mode 512 K dots (216 bytes) Character mode 4096 characters (212 bytes) Character generator ROM 7360 bits · European character support Character font...
