1 / 18 page Ordering number : EN5946 O1698RM (OT) No. 5946-1/18 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. 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: 5 × 7 dots 160 characters Character font: 5 × 11 dots 32 characters (Can be expanded by up to 4 KB using external ROM.) • Supports interfacing with 8-bit microcontrollers. • Display duty (program selectable) — From static to 1/256 duty • 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 SANYO Electric Co.,Ltd.
