T6K04

The T6K04 is a kind of driver for a small or medium scale dot matrix graphic LCD. It has a 8 bit interface circuit and generates all timing signals for display with on-chip oscillator. It receives 8-bit data from a MPU, latches the data to on-chip RAM, and display the image on LCD (the data on the display RAM correspond to the dots of display). It has 128 column driver outputs and 64 row driver outputs so as to drive 128 dots by 64 dots LCD on a single. The other functions, it has resistors to divide bias voltage, power supply OP-Amp, DC-DC converter (doubler, tripler, quadruppler) and contrast control circuit so as to drive LCD with a single power supply.

There are some features of T6K04 as follows: (1)on-chip display RAM: capacity: 128*64=8192 bit; (2)display RAM data: display data="1" (LCD turn on); display data="0" (LCD turn off); (3)1/32, 1/48, 1/56, 1/64 duty cycle; (4)word length of display data can changed 8 bit/word or 6 bit/word in compliance with a charater font; (5)LCD driver outputs 128 column driver outputs and 64 row driver outputs; (6)interfacing with 80 series MPU; (7)on-chip oscillator with one external resistor; (8)low power consumption; (9)on-chip resistors to divide bias voltage, on-chip OP-Amp for LCD supply, on-chip DC-DC converter, on-chip contrast control circuit; (10)CMOS process; (11)operating voltage except LCD drive signal: 2.7 to 5.5 V; (12)operating voltage of LCD drive signal must maintain VDD-VEE216.5 V, VEE1VEE2 ; (13)package: TCP.

The following is about the maximum ratings about T6K04 (Ta=25): (1)supply voltage 1, VDD: -0.3 to 7.0 V; (2)supply voltage 2, VLC1, 2, 3, 4, 5, VEE1, VEE2: VDD-18.0 to VDD+0.3 V; (3)input voltage, VINP: -0.3 to VDD+0.3 V; (4)operating temperature, Topr: -20 to 75; (5)storage temperature, Tstg: -55 to 125.
