PRELIMINARY
80 Output LCD Segment Driver IC
Notice: Sitronix Technology Corp. reserves the right to change the contents in this document without prior notice. This is not a final
specification. Some parameters are subject to change.
DESCRIPTION
The ST8008 is a 80-output segment driver IC suitable for driving small/medium scale dot matrix LCD panels, and is
used in PDA or electronic dictionary. The ST8008 is good as a segment driver, and it can create a low power
consuming, high-resolution LCD.
FEATURES
Number of LCD drive outputs: 80
Supply voltage for LCD drive: Max +16V
Supply voltage for the logic system: +2.5 to +5.5 V
Low power consumption
Package: 96-pin COB.
(Segment mode)
Shift clock frequency
- 20 MHz (MAX.): VDD = +5.0 ± 0.5 V
- 15 MHz (MAX.): VDD = +3.0 to + 4.5 V
- 12 MHz (MAX.): VDD = +2.5 to + 3.0 V
Adopts a data bus system
4-bit parallel / serial input modes are selectable with a mode (P/S) pin
Automatic transfer function of an enable signal
Automatic counting function which, in the chip selection mode, causes the internal clock to be stopped by
automatically counting 80 bits of input data
Line latch circuits are reset when XDISPOFF active
