LCD Driver IC with Key Input Function
Description
PT6583
PT6583 is an LCD Driver IC utilizing CMOS Technology. It can drive up to 171 segments and control up
to a maximum of 4 General Purpose Output Ports. Key Scan Circuit, Built-in Voltage Detection Type
(VDET) Reset Circuit, Sleep Mode, 1/3 Duty - 1/2 Bias and 1/3 Duty - 1/3 Bias Drive Techniques, Forced
All Segments OFF function are supported and provided into a single chip having the highest performance

(UP TO 30 KEYS)
Notes:
1. A capacitor can be connected to the power supply line to make the Power Supply Voltage
VDD rise time (when power is applied) and the power supply Voltage VDD fall time (when
power drops) are at least 1ms when PT6583 is reset via VDET.
2. If the /RST Pin is not used to initiate the System Reset Function, it must be connected to
VDD.
3. The DO Pin is an open-drain output and therefore needs a pull-up resistor. This resistor must
be between 1k to 10k Ohms. The value of this resistor must be in accordance with that the
capacitance of the external wiring so that the signal waveforms are in proper form.
4. C>0.047uF
