COMPONENT DATA OM 1058 Infra-Red CAR-KEY Transmitter OM1058 in case SO-8 1. DESCRIPTION AND APPLICATION This device is intended to be used in an infra-red remote-control car-key to transmit, when a button is pushed, an individual code to a receiver in the car to alternately open and lock the doors. The code is stored in a 24-bit EEPROM which is programmed by the equipement manufacturer. An input selects between a single or a repetitive transmission. It uses a fixed frequency to code the data. This device is identical to an OM1058. FIGURE 1 : "Block Diagramm" OUT MODE PROG SERCLK VDD VSS RCOS I/O EEPROM RCOSC LOGIC P.D.R 1 of 1 OM1058.doc COMPONENT DATA OM 1058 2.
