LCD Driver IC

DESCRIPTION

The PT6584 are 1/4 duty LCD display drivers that can directly drive up to 220 segments and can

control up to four 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.

FEATURES

APPLICATION

PT6584 V1.1

x Key input function for up to 30 keys (A key scan is performed only when a key is pressed.)

x 1/4duty - 1/2bias and 1/4duty

x Sleep mode and all segments off functions that are controlled from serial data

x Segment output port/general-purpose output port function switching that is controlled from serial

x Serial data I/O supports CCB format communication with the system controller

x Direct display of display data without the use of a decoder provides high generality

x Independent VLCD for the LCD driver block (VLCD can be set to in the range VDD-0.5 to 6.0V.)

x Provision of an on-chip voltage-detection type reset circuit prevents incorrect displays

x RES pin provided for forcibly initializing the IC internal circuits

x RC oscillator circuit

x Electronic Equipment with LCD Display

data

- 1/3bias drive schemes can be controlled from serial data (up to 220 segments).
