65COM / 132SEG DRIVER & CONTROLLER FOR STN LCD
The TL0324S is a driver and controller LSI for graphic dot-matrix liquid crystal display systems.
It contains 65 common and 132 segment driver circuits.
This chip is connected directly to a microprocessor (MPU), accepts serial or 8-bit parallel display data and
stores in an on-chip Display Data RAM (DDRAM) of 65 x 132 bits.
It provides a high-flexible display section due to one to one correspondences between on-chip DDRAM bits
and LCD panel pixels.
And it performs DDRAM read / write operation with no externally operating clock to minimize power
In addition, because it contains power supply circuits necessary to drive liquid crystal, it is possible to make a
display system with the fewest components.
