Remote door control is becoming very popular in automobiles and in private homes. In
automobiles, the simplest application controls door locks, but more sophisticated uses
include comfort control and turning burglar alarms on and off. A combination of the auto
and home applications will allow a single electronic key to control automobile doors and
burglar alarm, home burglar alarm, garage door opener, and home lighting. A hand-held,
reliable electronic key capable of controlling all these functions must be contained in a
small package that consumes very little power.
COP8SAA7 has the basic requirements to meet the needs of these applications:
4-26
• A 16 pin small-outline (SO) package
• A permanently powered HALT mode that consumes typically less than 4 A
• Reverse battery protection
• Fixed code/rolling code capabilities
• Four channels
• Single-chip solution
• End-of-line programming
• 1K bytes ROM and 64 bytes RAM
• WATCHDOG circuitry
