ST14 CODEC – IR/RF Remote Control Encoder/Decoder IC
[attachment=54667]
Overview
ST14 CODEC is Radio Frequency and Infrared
encoder/decoder IC for remote control applications
having unique features and flexibility not available with
other remote control encoder decoder ICs. ST14 is truly
a single-chip remote control solution.
Transmitter and Receiver can operate over Radio
Frequency or Infrared having four address and eight
data bits. Transmission and Reception over Infrared is
achieved by commonly available Infrared LED-Detector
and for RF any general purpose RF Transmitter-
Receiver pair would suffice.
The ST14 combines the functionality of both encoder
and decoder in a single package with several unique
features for enhanced operation and a reduced component count for transmitter and receiver circuits.
The MODE RX-TX (pin15) pin configures ST14 IC for encode or decode operation automatically at
power-up.
Features
· Encode / Decode on single chip
· Built in Oscillator
· Minimum External Components
· Wide operating voltage range. (2.0 - 5.5V)
· Single chip Encoding Decoding Mode
· 40kHz carrier for infrared transmission
medium
· 18 pin DIP package
Applications
· Burglar alarm system
· Smoke and fire alarm system
· Garage door controllers
· Car door controllers
· Car alarm system
· Security system
· Cordless telephones
· Other remote control systems
