Notes and Cautions
1. The V_SS2, V1 to V5 and V_OUT are relative to the VDD = 0V reference.
2. Insure that the voltage levels of V1, V2, V3, and V4 are always such that V_DD V1V2 V3 V4 V5.
3. Permanent damage to the LSI may result if the LSI is used outside of the absolute maximum ratings. Moreover,it is recommended that in normal operation the chip be used at the electrical characteristic conditions, and use of the LSI outside of these conditions may not only result in malfunctions of the LSI, but may have a negative impact on the LSI reliability as well.

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). Thanks to the built-in 55 common output circuits and 132 segment output circuits, the SED1568*** is capable of displaying 55  × 132 dots (11 columns ×4 lines using 11  ×12 dots Kanji font) with a single chip.

The SED1569 Series chips contain 53 common output circuits and 132 segment output circuits, so that a single chip can drive 53  × 132 dot display (capable of displaying 11 columns  × 4 rows of 11 × 12 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 lowpower 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 highperformance portable devices.
