DS89C450-K00 is an embedded micro controller belonging to the Development System 89C series from Dallas Semiconductor Company. It is basically a low cost, high performance, single chip 8-bit microcontroller with on-chip features like enhanced Enhanced A/D converter with 4 external, single ended input channels, a High Speed Programmable On-Chip PWM (SCPPWM) module, a compact Watchdog Timer, and a fast-speed serial interface. The DS89C450-K00 can be used for a variety of different applications, such as in automotive, medical and consumer applications.

A special feature of the DS89C450-K00 is the powerful onboard programmable XBC processor, which provides real-time processing capabilities. XBC stands for eXtensible Binary Controller, and it is able to execute instructions at up to 32MHz clock frequency. This allows the DS89C450-K00 to quickly respond to commands, and it also provides advanced functions such as real-time analysis and debugging.

The DS89C450-K00 can be used in different types of embedded systems. It can be used as a controller for various embedded applications such as medical and automotive systems. Additionally, it can be used for embedded software development, including programs written in C/C++ or assembly code. It can also be used in real-time control applications, such as sensing and monitoring applications. The DS89C450-K00 is suitable for use in any system that requires high performance and low power consumption.

The DS89C450-K00 has a 16-bit instruction and data bus so it can handle up to 64KB of on-chip program memory and 512KB of on-chip data memory. The device has four 8-bit input/output (I/O) ports, two analog-to-digital (ADC) channels and three timer/counter modules. Additionally, the device provides 64kB of on-chip flash program memory, 4kB of EEPROM, 4kB of RAM and two UARTs for serial communication.

The working principle of DS89C450-K00 is that when an instruction is sent from the CPU, it is passed through the memory, stored in the on-chip program memory, and then passed back to the CPU where it is executed. The CPU runs the instructions, which are stored in the program memory and then performs the necessary operations according to the instruction.

The device also includes features such as an Enhanced A/D Converter (EAC), High Speed Programmable Pulse Width Modulator (SPPWM) module and Compact Watchdog Timer which can collectively provide a powerful embedded system control solution. Additionally, the device also includes user configurable General-Purpose Input/Output (GPIO) pins to allow for user specific configurations.

In conclusion, the DS89C450-K00 is an ideal embedded system solution for various types of applications. It offers a number of features including a high performance XBC processor, 64kB of on-chip program memory, 4kB of EEPROM, 4kB of RAM, two UARTs for serial communication, an Enhanced A/D Converter, High Speed Programmable Pulse Width Modulator module and Compact Watchdog Timer all in a low power package. It can be applied to a variety of different embedded systems.
