IR CAR-KEY TRANSMITTER, OM1058 in case SO-8 - Laurent ...

COMPONENT DATAOM 1058Infra-Red CAR-KEY TransmitterOM1058 in case SO-81. DESCRIPTION AND APPLICATIONThis device is intended to be used in an infra-red remote-control car-key to transmit, when abutton is pushed, an individual code to a receiver in the car to alternately open and lock thedoors. The code is stored in a 24-bit EEPROM which is programmed by the equipementmanufacturer. An input selects between a single or a repetitive transmission. It uses a fixedfrequency to code the data.This device is identical to an OM1058.FIGURE 1 : "Block Diagramm"OUTMODEPROGI/OEEPROMSERCLKVDDVSSRCOSCLOGICP.D.RRCOS1 of 1 OM1058.doc
