PT6530 Datasheet, PDF (1/42 Pages) Princeton Technology Corp – LCD Driver IC

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

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.
