SED1565 Series

Dot Matrix LCD Driver

SSC5000Series

■ DESCRIPTION

The SED1565 Series is a series of single-chip dot matrix liquid crystal display drivers that can be connected directly

to a microprocessor bus. 8-bit parallel or serial display data sent from the microprocessor is stored in the internal

display data RAM and the chip generates a liquid crystal drive signal independent of the microprocessor. Because

the chips in the SED1565 Series contain 65 × 132 bits of display data RAM and there is a 1-to-1 correspondence

between the liquid crystal panel pixels and the internal RAM bits, these chips enable displays with a high degree

of freedom.

The SED1565 Series chips contain 65 common output circuits and 132 segment output circuits, so that a single

chip can drive a 65 × 132 dot display (capable of displaying 8 columns × 4 rows of a 16 × 16 dot kanji font). The

SED1567 Series chips contain 33 common output circuits and 132 segment output circuits, so that a single chip

can drive 33 × 132 dot display (capable of displaying 8 columns × 2 rows of 16 × 16 dot kanji fonts). Moreover, the

capacity of the display can be extended through the use of master/slave structures between chips.

The chips are able to minimize power consumption because no external operating clock is necessary for the display

data RAM read/write operation. Furthermore, because each chip is equipped internally with a low-power liquid

crystal driver power supply, resistors for liquid crystal driver power voltage adjustment and a display clock CR

oscillator circuit, the SED1565 Series chips can be used to create the lowest power display system with the fewest

components for high-performance portable devices.

■ FEATURES
