SED15A6

Dot Matrix LCD Driver

■ Support up to 55×102 Display

■ Built-in Power Supply Circuit for LCD

■ Few External Parts Required

■ OVERVIEW

The SED15A6 series is a single-chip liquid crystal display (=LCD) driver for dot-matrix LCDs that can be con-

nected directly to a microprocessor (=MPU) bus. It accepts 8-bit parallel or serial display data from a MPU,

stores it in an on-chip display data RAM (=DDRAM), and generates a LCD drive signal independent of the MPU

clock.

The use of the on-chip DDRAM of 65×102 bits and a one-to-one correspondence between LCD panel pixel dots

and on-chip DDRAM bits offer high flexibility in graphic display.

The SED15A6 series does not need external operation clock for DDRAM read/write operations, and has a on-

chip LCD power supply circuit featuring very low current consumption with few external components, and

moreover has a on-chip CR oscillator circuit.

And the SED15A6 does not need smoothing capacitor on the LCD power supply.

Consequently, the SED15A6 series can be realize a high-performance handy display system with a minimum

current consumption and the fewest components.

■ FEATURES

■ Direct display of RAM data through the display data RAM.

■ RAM bit data : “1” Non-illuminated

“0” Illuminated

(during normal display)

■ RAM capacity 65×102 = 6630 bits

■ Display driver circuits

SED15A6*

55 common output and 102 segment outputs

■ High-speed 8-bit MPU interface (The chip can be connected directly to the 8080 series MPUs and the 6800

series MPUs)

■ High-speed Serial interface are supported.

■ Abundant command functions

Display data Read/Write, display ON/OFF, Normal/Reverse display mode, page address set, display start

line set, column address set, display all points ON/OFF, LCD bias set, electronic volume, read/modify/write,

segment driver direction select, power saver, common driver direction select, V0 voltage regulation internal

resistor ratio set.

■ Low-power liquid crystal display power supply circuit equipped internally.

Booster circuit(with Boost ratios of Double/Triple/Quad, where the step-up voltage reference power supply

can be input externally)

• High-accuracy voltage adjustment circuit

(Thermal gradient –0.1%/°C)

• V0 voltage divider resistors equipped internally, V1 to V4 voltage divider resistors equipped internally,

electronic volume function equipped internally, voltage follower.
