Introduction: COP8SAA728M9 is an 8-Bit PicoPower microcontroller with on-chip peripherals, including I/O ports, timers, watchdog timer and A/D converter, designed for low-power operation. It has an internal oscillator and an integrated voltage regulator which allows the COP8SAA728M9 to operate on a wide range of input voltages. This microcontroller is an ideal solution for cost sensitive, low-power applications.

Application Field: The COP8SAA728M9 is designed for use in a variety of applications, including medical, automotive, industrial and consumer markets. It is widely used in applications such as automotive engine control systems, process control systems, security systems, televisions and other consumer products.

Working Principle: The COP8SAA728M9 uses an 8-bit architecture and is capable of executing up to 30 MIPS (Mega Instructions Per Second) at 5.1 V. It is capable of executing up to 40 MIPS at 3.0 V. The COP8SAA728M9 has a total of 8K Bytes of on-chip Flash memory, 1k bytes of SRAM, an 8x8 multiplier, and an on-chip Direct Memory Access Controller (DMA).

Power Supply: The COP8SAA728M9 operates with a single power supply. It can be supplied with power between 1.8V to 5.1V. There are several power-on reset sources, on-chip and external. The COP8SAA728M9 also has a low voltage detection circuit and an on-chip voltage regulator which enables it to tolerates changes in input voltage without resetting.

Clocking System: The COP8SAA728M9 has an integrated oscillator, with an accuracy of +/- 1%. The clock can be operated between 1MHz to 24 MHz. It also has an auto-frequency detection mode which can detect the system frequency between 0.5 MHz to 24 MHz.

Interrupts: The COP8SAA728M9 has three interrupt sources. An internal timer overflow or compare interrupt, an external interrupt and an external reset. There is also a watchdog timer that can trigger an interrupt after a user-defined timeout period. This allows for detection of system hangs and resetting of the system.

Peripheral Devices: The COP8SAA728M9 has an array of on-chip peripherals, including I/O ports, Timers, Watchdog Timer, A/D Converter, and USART. The USART is configurable to allow the use of either a serial or a parallel protocol. It is also possible to generate custom pulses from the I/O ports.

Conclusion: The COP8SAA728M9 is an 8-bit low-power microcontroller with integrated on-chip peripherals, making it ideal for consumer, industrial, and automotive applications. The COP8SAA728M9 has an integrated oscillator and on-chip voltage regulator, which allows it to operate in a wide range of input voltages. It also has an array of on-chip peripherals including I/O ports, timers, watchdog timer, and A/D converter. The USART is configurable to allow the use of either a serial or a parallel protocol making the COP8SAA728M9 an ideal solution for cost sensitive, low-power embedded applications.
