General Description:

VK1623S is a RAM Mapping 48x8 LCDDriver，It can support LCDscreens with a maximum of 384 pattern(48SEGx8COM).Only 3 or 4 lines arerequired to communication interface with the VK1623S,it is used to configuredisplay parameters and transfer display data, and can also enter the standbymode through Power down command（by Cmd LCD OFF,SYS DIS）.

Features:

• Operatingvoltage:2.4-5.2V

• Built-in32kHz RC oscillator（default）

• External32.768kHz crystal（OSCO,OSCI）

• 1/4BIAS

• 1/8duty (8 COM)

• Built-in48×8 bit display RAM

• Selectionof buzzer frequencies 2kHz、4kHz

• STANDBYmode（by Cmd LCD OFF,SYSDIS）

• 8kinds of time base/WDT clock sources

• Timebase or WDT overflow output （/IRQ pin）
• 3 or 4 wire serial interface

• Softwareconfiguration LCD parameters

• Datamode and command mode instructions

• Read/Writeaddress auto increment

• Threedata accessing modes

• VLCDpin for adjusting LCD operating voltage（

• Package:

LQFP100(14.0mm x 14.0mm PP=0.5mm)

QFP100(20.0mm x 14.0mm PP=0.65mm)
