SED1533DF Datasheet | Epson Company

DESCRIPTION The SED1530 series is a single-chip LCD driver for dot-matrix liquid crystal displays (LCD’s) which is directly connectable to a microputer bus. It accepts 8-bit serial or parallel display data directly sent from a microputer and stores it in an on-chip display RAM. It generates an LCD drive signal independent of microprocessor clock. The use of the on-chip display RAM of 65 × 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. As a total of 133 circuits of mon and segment outputs are incorporated, a single chip of SED1530 series can make 33 × 100-dot (16 × 16-dot kanji font: 6 columns × 2 lines) displays, and a single chip of SED1531 can make 65 × 132-dot (kanji font: 8 columns x 4 lines) displays when the SED1531 is bined with the mon driver SED1635. The SED1532 can display the 65x200-dot (or 12-column by 4-line Kanji font) area using two ICs in master and slave modes. As an independent static indicator display is provided for time-division driving, the low-power display is realized during system standby and others. 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 a minimum current consumption and a smallest LSI configuration. Two types of SED1530 series are available: one in which mon outputs are arranged on a single side and the other in which mon outputs are arranged on both sides. s FEATURES q Direct RAM data display using the display RAM. When RAM data bit is 0, it is not displayed. When RAM data bit is 1, it is displayed. (At normal display) q RAM capacity: 65 × 132 = 8580 bits q High-speed 8-bit microprocessor interface allowing direct connection to both the 8080 and 6800. q Serial interface q Many mand functions:...
