LX527 User’s Guide
Description
LX527 is designed by CMOS technology,can storage ISN and study code beforehand, it is
decoded by software;ISN has 20bit can storage 1048576 for combination,this can reduce any
code collision.
Main Features
1 ．low power consumption quiescent current＜1uA ；
2 ．operating voltage Vcc=2.4 - 13.0V；
3 . input four key-press through combination，that can
assemble 8 key-press mostly;
4 ．single oscillator circuit，need one external
resistor only.
5．small volumne8 package by SSOP ，it is perfect upgrade
product of LX2260；
6 ．it is compatible with FP527 absolutely.
