1. DESCRIPTION

The SED15A6 series is a single-chip liquid crystal

display (=LCD) driver for dot-matrix LCDs that can be

connected 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.

• 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)

• V⁰voltage divider resistors equipped internally,

V¹to V4 voltage divider resistors equipped internally,

electronic volume function equipped internally,

voltage follower.

• Component that can be omitted (you may omit the

smoothing capacitor on the voltage follower).

• CR oscillator circuit equipped internally(external clock

can also be input)

• Extremely low power consumption

Operating power when the built-in power supply is

used(an example)
