T7932

The T7932 is a column (segment) driver for small or medium-scale dot matrix graphic LCD.The T7932 realizes a low power LCD system using the CMOS Si-gate process.The T7932 stores 4-bit/8-bit display data transferred from a microprocessor.The T7932 can be combined with a T7933 to construct an LCD system.An MPU can drive the T7932 directly.

Features of the T7932 are:(1)dot matrix graphic LCD colum driver with display RAM;(2)interface with 80-series MPU and 68-series MPU(4-bit/8-bit);(3)selectable column output pin arrangement;(4)relation of RAM data;(5)display RAM capacity;(6)LCD drive output is 50;(7)duty is can be controlled by external input signal;(8)various functions;(9)low power consumption:display data read/write,display ON/OFF,set address,set display start page,read status,set up/down mode;(10)logic power supply is 5V±10%;(11)80-pin flat plastic package .
