ROW DRIVER LSI FOR A DOT MATRIX GRAPHIC LCD
T7933 TOSHIBA CMOS DIGITAL INTEGRATED CIRCUIT SILICON MONOLITHIC
T7933 ROW DRIVER LSI FOR A DOT MATRIX GRAPHIC LCD
The T7933 is a row (common) driver LSI for a small-or
medium-scale dot matrix graphic LCD. The T7933 realizes a low
power LCD system using the CMOS Si-Gate process.
The T7933 generates timing signals for the display using a
built-in oscillator and also controls the T7932 column (segment)
LCD driver.
Five duty options are available: 1/8, 1/12, 1/16, 1/24 and 1/32. The
T7933 has 32 low-impedance output row drivers (1 kΩ max).
The T7933 includes internal resistors to the divide bias voltage
for 1/16 duty and 1/32 duty displays.
Features Row signal output for LCD LCD drive outputs : 32 (low impedance) Built-in oscillator (additional external resistor and capacitor) Built-in voltage dividers for 1/16 and 1/32 duty cycle Duty : 1/8, 1/12, 1/16, 1/24, 1/32 Low power consumption Logic power supply : VDD = 5 V ± 10% 60-pin plastic flat package
Weight: 1.1g (typ.)
