Preliminary WFP7152
240 OUTPUT SEGMENT/COMMON
STN LCD DRIVER
Publication Release Date: July 6, 2001
- 1 -
Revision A1
1. GENERAL DESCRIPTION
The WFP7152 is a 240 output segment/common driver LSI suitable for driving large scale STN dot
matrix LCD panels.
Through the use of SST (Super Slim TCP) technology. It is ideal for substantially decreasing the size of
the frame section of the LCD module.
The WFP7152 is good both segment driver and common driver and a low power consuming, high-
precision LCD panel display can be assembled.
2. FEATURES AND BENEFITS
(Segment mode)
Shift clock frequency up to 20 MHz (VDD = 5V
±10%)
Adopts a data bus system
4-bit/8-bit parallel input modes are selectable with MD pin.
Automatic transfer function of an enable signal.
Automatic counting function which in the chip select mode causes the internal clock to be stopped by
automatically counting 240 of input data.
Line latch circuit reset function with DISPOFF active.
(Common model)
Shift clock frequency up to 4 MHz
Built-in 240-bits bi-directional shift register (divisible into 120-bits x 2)
(120-bits shift register x 2)
(1) Y1 - Y240 single mode
(2) Y240 - Y1
(3) Y1 - Y120, Y121 - Y240
Dual mode
(4) Y240 - Y121, Y120 - Y1
The above 4 shift directions are pin-selectable
Shift register circuit reset function with DISPOFF active.
(Others)
Supply voltage for LCD drive: +15 to +30V
Number of LCD drive outputs: 240
Low output impedance
Low power consumption
Supply voltage for the logic system: +2.5 to +5.5V
CMOS silicon gate process (P-type silicon substrate)
