PF777-03 SED1530 Series SED1530 Series Dot Matrix LCD Controller Driver SSC5000Series q Ultra Low Power Consumption q Built-in Power Supply Circuit for LCD q 133 Driver Output s DESCRIPTION The SED1530 series is a single-chip LCD driver for dot-matrix liquid crystal displays (LCD’s) which is directly connectable to a microcomputer bus. It accepts 8-bit serial or parallel display data directly sent from a microcomputer 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 common 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 combined with the common 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 common outputs are arranged on a single side and the other in which common 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 command functions: Read/Write Display Data, Display ON/OFF, Normal/Reverse Display, Page Address Set, Set Display Start Line, Set Column Address, Read Status, All Display ON/OFF, Set LCD Bias, Electronic contrast Controls, Read Modify Write, Select Segment Driver Direction, Power Save 1 SED1530 Series s LINE UP Type 1 [VREG Temperature gradient 0.2% / °C] • Specifications (for chip models) Name SED1530D0* SED1530DA* SED1531D0* SED1532D0* SED1532DB* Duty 1/33 1/33 1/65 1/65 1/65 LCD bias 1/5, 1/6 1/5, 1/6 1/6, 1/8 1/6, 1/8 1/6, 1/8 Segment driver 100 100 132 100 100 COM driver 33 33 0 33 33 Display area 33 × 100 33 × 100 65 × 132 65 × 200 65 × 200 Remarks COM single-side assignment COM dual-side assignment SED1635 is used for COM.
