Application Field

The KXPC823VR81B2T is a 8-bit microprocessor from the RISC family of microprocessors and is often used in a variety of embedded applications, such as point-of-sale systems, vending machines, automative electronic systems, and even industrial applications.

The device boasts of high performance and low power consumption, with a typical active current of 7 mA and a maximum active current of 18 mA. This ensures that the device runs efficiently and reliably in demanding applications, while also keeping its power consumption low.

The device is also pin and code compatible with the popular 80C51 family of microcontrolers, making it an easy upgrade or replacement in existing systems.

The KXPC823VR81B2T also supports multiple interrupts and a real-time programmable clock, allowing it to handle more advanced applications.

Working Principle

The KXPC823VR81B2T has a Harvard architecture which consists of a central processing unit (CPU), a read-only memory (ROM) and a random access memory (RAM).

The CPU contains an arithmetic logic unit (ALU) and a control circuit that execute instructions stored in the ROM. The ALU performs the calculations, while the control unit fetches the instructions from the ROM and interprets them. The RAM is where data is stored during operations.

The CPU can also communicate with peripherals, such as serial devices, USB, Ethernet and other devices through an external bus interface. The CPU is also equipped with a watch dog timer (WDT), which restarts the CPU if it malfunctions or gets stuck in an infinite loop.

The KXPC823VR81B2T also supports on-chip debugging and a boot loader, making it easier to develop applications and debug hardware and software issues.

Conclusion

The KXPC823VR81B2T is a powerful and versatile embedded microprocessor with low power consumption and high performance. It is especially useful for point-of-sale systems, vending machines, automotive electronic systems and industrial applications. Its Harvard architecture, on-chip debugging and boot loader support, make it a great choice for embedded applications.
