PTC PT6520_10

PT6520
LCD Driver IC
DESCRIPTION
PT6520 is a dot matrix LCD driver IC. The bit
addressable display data which is sent from a
microcomputer is stored in a build-in display data RAM
and generates the LCD signal.
The PT6520 incorporates innovative circuit design
strategies to assure very low current dissipation and a
wide range of operating voltages. The PT6520 permits
the user to implement high-performance handy
systems operating from a miniature battery.

Notes:
1. Command 1: Display On/Off Commands
2. When IC power is applied for the first time, the contents of the Display RAM are not defined; thus, it is strongly suggested that the contents of the

7. When D0 to D7 and FR are high impedance.
8. During continual writer access at a frequency of tcyc. Current consumption during access is effectively proportional to the access frequency.
9. For a voltage differential of 0.1V between input (V1,…, V4) and output (COM, SEG) pins. All voltages within specified operating voltage range.
10. PT6520 only. Does not include transient currents due to stray and panel capacitances.
