CMOS IC
LCD Driver with Level Meter
Ordering number:ENN2292B
LC7583N
SANYO Electric Co.,Ltd. Semiconductor Company
TOKYO OFFICE Tokyo Bldg., 1-10, 1 Chome, Ueno, Taito-ku, TOKYO, 110-8534 JAPAN
Overview
The LC7583N is an LCD driver that can be microcomputercontrolled to provide segment display and level meter dis-
play.
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.
