SED1575 Series

Dot Matrix LCD Driver

■Support up to 65×168 Display

■Built-in Power Supply Circuit for LCD

■ OVERVIEW

The 1575 series is a 1-chip dot matrix liquid crystal driver that can be connected to the bus of a microcomputer.

It stores the 8-bit parallel or serial display data sent from the microcomputer in the built-in display data RAM and

generates liquid crystal drive signals independently of the microcomputer. Since it incorporates 65 × 200 bits of

the display data RAM and the one-dot pixel of the liquid crystal panel and one bit of the built-in RAM have a one-

to-one correspondence, it enables display with the high degree of freedom.

The SED1575 series incorporates 65 circuits of the common output and 168 circuits of the segment output and

can display 65 × 168 dots (capable of displaying 10 columns × 4 rows of a 16 × 16 dot kanji font) using the single

chip. The SED1577 Series incorporates 33 circuits of the common output and 200 circuits of the segment

output and can display 33 × 200 dots (capable of displaying 12 columns × 2 rows of a 16 × 16 dot kanji font). It

can also expand the display capacity by using the two chips for the master and slave configuration.

Since the read/write operation of the display data RAM does not require external operation clocks, the

SED1575 series can be operated with the minimum current consumption. Since it also incorporates a liquid

crystal drive power supply with low current consumption, liquid crystal drive power supply voltage adjusting

resistor, and display clock CR oscillator circuit, it can provide a display system for high performance handy

equipment with the minimum current consumption and the minimum parts configuration.

■ FEATURES

■ Direct display of RAM data using the display data RAM

RAM bit data

“1” .... goes on.

“0” .... goes off (at display normal rotation).

■ RAM capacity

65 × 200 = 13,000 bits

■ Liquid crystal drive circuit

The SED1575 Series

65 circuits for the common output and 168 circuits for the segment output

The SED1577 Series

33 circuits for the common output and 200 circuits for the segment output

■ High-speed 8-bit MPU interface (Both the 80 and 68 series MPUs can directly be connected.)/serial inter-

face enabled

■ Abundant command functions
