The architecture, features, and flexibility of the COP8SAx7 family of microcontrollers
provide cost-effective solutions for security/monitoring by eliminating external
components from the circuit. Figure 4-20 demonstrates an application example of a
security/monitoring system using the COP8SAC7. The application also illustrates
interfacing the device to a number of specialized peripherals using a minimum number
of I/O lines.
COP8SAC7 features suited for these applications include:
• Low-power HALT and IDLE
• 16-bit timers, each with two 16-bit registers supporting processor independent
• MICROWIRE/PLUS serial communication
