T6B20

The T6B20 is a dot matrix LCD controller and driver.The T6B20 realizes low power consumption for an LCD system using CMOS Si-gate technology.The T6B20 can display alphanumerics,kana and symbols corresponding to serial data reveived from an MPU.

Features of the T6B20 are:(1)built in controller for character-type LCD;(2)direct interface with MPU;(3)data transfer clock is fosc=250kHz typ;(4)display data RAM is 80*8 bits;(5)character generator ROM is 12000 bits;(6)character generator RAM is 512 bits;(7)built-in key matrix scan controller;(8)built-in 2*8 LED controller;(9)built-in LCD drivers.

The absolute maximum ratings of the T6B20 can be summarized as:(1):the parameter is supply voltage 1,the symbol is VDD,the value is -0.3 to 7.0,the unit is V;(2):the parameter is supply voltage 2,the symbol is VLC1 to VLC5,the value is VDD-13.5 to VDD+0.3,the unit is V;(3):the parameter is input voltage,the symbol is VIN,the value is -0.3 to VDD+0.3,the unit is V;(4):the parameter is operating temperature,the symbol is Topr,the value is -20 to 75,the unit is ;(5):the parameter is storage temperature,the symbol is Tstg,the value is -55 to 125,the unit is .The referenced to VSS=0V,the ensure that the following condition is always maintained.
