General Description
The NT7534 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 in an on-chip display RAM. It generates an LCD drive signal independent of 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 NT7534 contain 65 common output circuits and 132 segment output circuits, so that a single chip of NT7534 can make maximum 65 x 132 or 49 x 132 or 33 x 132 dots display with the 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.
