Overview
The LC7583N is an LCD driver that can be microcomputercontrolled to provide segment display and level meter display.

FEATUREs
• The serial data address is “5”.
• 1/2duty, 1/2bias, 66 segments (max) (Except ADC output, DSP input display).
• 5-bit AD converter and three selections of level output shown below.
    (1) 13 dots x 2ch Log scale
    (2) 13 dots x 2ch Linear scale
    (3) 26 dots x 1ch Linear scale
• 2 display (DSP) pins for direct display.
• Microcomputer-controlled data input using 3 pins for serial data input and control.
• The full scale of the AD converter is 31/48Vref. The Vref is variable (with Vref pin).
• Available for increased use in general-purpose applications because no decoder is required to display the segment data.
• Control bits used to cause the segment output and AD output to be lighted/unlighted.
• RES pin used to cause the initial mode to be entered.
