PT6530

LCD Driver IC

Princeton Technology 

DESCRIPTION

The PT6530 are 1/3 duty and 1/4 duty LCD display

drivers that can directly drive up to 300 segments and

can control up to eight general-purpose output ports.

These products also incorporate a key scan circuit that

accepts input from up to 30 keys to reduce printed

circuit board wiring.

APPLICATION

• Electronic Equipment with LCD Display

LCD Driver IC

FEATURES

• Key input function for up to 30 keys (A key scan is

performed only when a key is pressed.)

• 1/3 duty and 1/4 duty drive schemes can be

controlled from serial data.

• 1/2 bias and 1/3 bias drive schemes can be

controlled from serial data.

• Capable of driving up to 228 segments using 1/3

duty and up to 300 segments using 1/4 duty.

• Sleep mode and all segments off functions that are

controlled from serial data.

• Segment output port/general-purpose output port

function switching that is controlled from serial

data.

• Serial Interface for clock, Data Input, Data Output,

Strobe pins.

• Direct display of display data without the use of a

decoder provides high generality.

• Independent VLCD for the LCD driver block (VLCD

can be set to in the range VDD – 0.5 to 6.0V)

• Provision of an on-chip voltage-detection type

reset circuit prevents incorrect displays.

• RES pin provided for forcibly initializing the IC

internal circuits.

• RC oscillator circuit.
