Control44

4 bit Address - 4 bit Data encoder/decoder

Control44 is a 4 bit address, 4 bit data

encoder and decoder combined in a single

IC. This device can operate in either Encode

or Decode mode. It uses 1kbps differential

Manchester bit balancing with preamble

and

checksum.CTR44

specifically

designed to be used in RF remote control

applications. It is available in 20pin SSOP,

18pin SOIC and PDIP packages.

Features

•

Operating voltage (temperature):

3.0V-5.5V for standard version (-40°C to +125°C)

2.0V-5.5V for low voltage version (-40°C to +85°C)

Draws <2mA without external load

•

4 bit address and 4 bit data

16 different remotes with 4 controls each

Single packetised transmission for fast activation

Maximum usage of the range capability of an RF module

Adequate preamble to settle data slicer in the receiver.

Extra wake up preamble to allow for transmitter power up time requirements

Differential Manchester encoding of address, data and checksum

Synchronisation codes and checksum to reduce false triggering on noise

Suitable to be used with Narrow Band FM radio modules

Ceramic resonator or crystal oscillator up to 20MHz

Data rate up to 5.6kbps

Minimum external component requirement

4 wire, push button and latched push button modes

Custom address, data bit variations available subject to minimum order quantity

Applications

•

Security and Alarm systems

Emergency assistance call system

Status reporting and monitoring systems

RF Remote control systems

Industrial controls

HVAC controls

Simple On/Off switching

Long range telecontrol with Narrow Band FM radios
