Product specification

Infrared remote control transmitter RC5

PCA8521

SYSTEM DEVELOPMENT

Software (RC8521)

A PC program is provided that enables the user to fill in system and command codes for each key number in each bank.

This program converts the input data into a ROM code-file needed to produce the metal mask and to program an EPROM

to be used in the hardware emulator.

Hardware (OM4839)

An emulator is available that functionally emulates the IC. An EPROM with the ROM code information is inserted into the

emulator to produce the required remote control codes corresponding to the keys in the prototype device.
