T6K01 2002-01-07 1 toshiba cmos digital integrated circuit silicon monolithic T6K01 column driver lsi for a dot matrix graphic lcd the T6K01 is a column (segment) driver for a dot matrix graphic lcd. the T6K01 offers low power consumption, due to the cmos si-gate process. it is designed to interface directly with a microprocessor unit (mpu). a program running on the mpu can drive the T6K01 asynchronously. the T6K01 stores data transferred from the mpu in its built-in ram. the data stored in the built-in display ram corresponds to the image on the lcd screen; the data is converted into the lcd drive signal. a configuration of two T6K01s and one t6c03 can be used to drive a 480 160-dot lcd. features dot matrix graphic lcd column driver with display ram display ram capacity: 160 lines 240 outputs = 38400 bits lcd drive output: 240 interface: 8-bit mpu relation between ram data and display ram bit data = 1 display on ram bit data = 0 display off display off function low power consumption logic power supply: 2.7 to 3.3 v lcd power supply: 8.0 to 26.0 v cmos process package: tcp (tape carrier package)
