4.10.1 Typical Applications
4.10.2 Flexibility
The COP8SAA7 can operate in both RF and IR applications and fixed and rolling code
implementations with or without external EEPROM.
4.10.3 Low Cost
A minimum number of external components are required. Single-cell operation for fixed-
code applications is possible, and reverse battery protection prevents damage.
4.10.4 Small Transmitter Size
The device is contained in a small 16-pin SO package.
4.10.5 Low-Cost Version for Rolling Code
This type of application should be implemented with EEPROM, which contains basic
code, actual code, and some diagnostic and correctional data. Because the COP8SAA7
does not require a large number of external components, external memory contained in
an SO package will not significantly impact the overall size of the system. Figure 4-13
shows a low-cost version of a rolling code IR transmitter implemented with the
COP8SAA7 and National Semiconductor's NM93C06 EEPROM.
4.10.6 Receiver Circuit
The receiver circuit usually has additional control functions, which require a large
amount of software. In some cases, EEPROM is required for diagnostics.
• Multi-input wakeup signal
• Burglar alarms
• Gate and garage door openers
• Central locking
• IR/RF transmission
