1 / 45 page  T6K14 2002-01-16 1 TOSHIBA CMOS DIGITAL INTEGRATED CIRCUIT SILICON MONOLITHIC T6K14 COLUMN AND ROW DRIVER LSI FOR A DOT MATRIX GRAPHIC LCD The T6K14 is a driver for a small-to-medium-sized dot matrix graphic LCD, especially for reflective color STN LCD. It realizes a 4-color or 4-gray-scale display. This driver can be interfaced to the MPU via an 8-bit (68/80-series) or a serial interface, and is operated asynchronously with the MPU. Since the T6K14 contains a CR oscillator, it can generate the timing signals required for the LCD. Since the T6K14 has 128 outputs for the LCD drive (segment) signals that constitute display data, 65 outputs for the LCD drive (common) signals that constitute scanning signals and 65 × 128 × 2 bits display RAM, this single device allows you to drive an LCD panel comprised of up to 128 × 64 dots and 128 icons with a minimize of power requirement. It has 4 gray-scale function. The display RAM of this driver is a 2 port RAM so that the MPU accesses without any wait time. It has various power circuits such as a voltage regulators, voltage divider resistors, a power supply op-amp, a contrast control circuit, a temperature compensation circuit, and DC-DC converter ( ×2, ×3, ×4, ×5 ). All these circuits enable the LCD panel to be driven with a single power supply. Features l LCD driver output : 64 rows + 128 columns + 128 icons l Built in display RAM : 65 × 128 × 2 = 16640 bits, 2-port RAM l Gray scale : 4 gray-scale selectable l Word length : 8-bit/word l Duty cycle : 1/2 duty (power save mode) 1/35, 1/49, 1/57, 1/65 duty selectable (normal display mode)Display mode l Display modes : Normal mode (Full display) Power save mode (Icon display) Stand by mode (Clock stopped) l Clock oscillator : CR oscillator with external resistors Low frequency operation 82 kHz oscillation for FR frequency 70 Hz (1/65 duty) l Power circuit : Voltage regulator, Voltage divider, Voltage follower op-amp. DC-DC converter (×2, ×3, ×4, ×5), Temperature compensation circuit, Contrast control circuit. l CPU interface : Interfacing with 68/80 series MPU and Serial Interface l Logic operating voltage : VDD = 2.4 to 3.3 V, VIN = 2.7 to 3.3 V l LCD drive voltage : VCC1, 2 = 6.0 to 16.5 V, if case of used the voltage Regulator, VCC2 output voltage at 12.5 V or 11.0 V (typ.) Ta = 25°C l CMOS process l Low power consumption : ISS = 200 µA (typ.) Condition : VDD = 2.7 V, VIN = 2.7 V, using the DC-DC converter (×5), no data access, op-amp on, fosc = 82 kHz (internal clock), no load, 1/65 duty, temperature compensation circuit off. l Package : Product Package T6K14 (×××, ×××) TCP (Tape carrier package) JBT6K14-AS Gold bump chip Please contact with Toshiba agents for each packaging outline dimensions. TCP (Tape Carrier Package) Lead Pitch IN OUT T6K14 (UBW, 5NS) 0.60 0.23 Unit: mm |
