General Description

The NT7532 is a single-chip LCD driver for dot-matrix liquid crystal displays, which is directly connectable to a microcomputer bus. It accepts 8-bit parallel or serial display data directly sent from a microcomputer and stores it on an on-chip display RAM. It generates an LCD drive signal independent from the microprocessor clock.

The set of the on-chip display RAM of 65 x 132 bits and a one-to-one correspondence between LCD panel pixel dots and on-chip RAM bits permits implementation of displays with a high degree of freedom.

The NT7532 contain 65 common output circuits and 132 segment output circuits, so that a single NT7532chip can make 65 x 132, 55 x 132, 49 x 132 and 33 x 132 dot displays with pad option (DUTY1, DUTY0).

No external operation clock is required for RAM read/write operations. Accordingly, this driver can be operated with a minimum current consumption and its on-board low-current-consumption liquid crystal power supply can implement a high-performance handy display system with minimum current consumption and the smallest LSI configuration.
