| Ordering number:ENN2292B CMOS IC LC7583N LCD Driver with Level Meter Overview The LC7583N is an LCD driver that can be microcomputercontrolled to provide segment display and level meter display. Package Dimensions unit:mm 3057-QIP64A [LC7583N] 20.0 14.0 1.0 3.0 1.0 48 49 32 0.35 0.8 0.35 3.0 1.0 33 0.15 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. 20.0 14.0 0.8 17 1.0 64 1 16 2.45max 2.15 16.6 1.7 SANYO : QIP64A unit:mm 3026B-QIP64B [LC7583N] 19.6 14.0 1.0 48 49 0.8 0.35 2.8 1.0 33 32 19.6 14.0 0.8 0.35 2.8 1.0 1.0 64 1 16 17 Any and all SANYO products described or contained herein do not have specifications that can handle applications that require extremely high levels of reliability, such as life-support systems, aircraft's control systems, or other applications whose failure can be reasonably expected to result in serious physical and/or material damage.
