LC7041

ID LOGIC® Interface with PLL

Overview

The LC7041 is the central IC to the ID LOGIC Module

and Electronic Tuning Radio.

It performs the interface between the receiver’s main mi-

croprocessor and ID LOGIC’s 256kB database ROM and

its 2kB update RAM. The LC7041 also contains the Phase-

Locked Loop (PLL) circuitry responsible for electronic

tuning and it offers several I/O ports.

The LC7041 permits the easy integration of the ID LOGIC

Module in a receiver. It contains all the appropriate soft-

ware to send and receive serial instructions and data to and

from the receiver’s main microprocessor. An instruction is

given simply by having the main microprocessor send a

one byte-long function code followed, when necessary, by

the appropriate data. Upon execution, the LC7041 returns

its response data, if any, to the microprocessor for display

or other processing. Further the SUPER DX search con-

trol function is added to the LC7041.

Note

It is necessary to enter into an “ID LOGIC Licensing Con-

tract” with PRS. Corp. before sample devices can be

shipped.
