Abstract
The AT89C2051 is a low-voltage, high-performance CMOS 8-bit microcomputer with 2K bytes of Flash programmable and erasable read-only memory (PEROM). The device is manufactured using Atmel’s high-density nonvolatile memory technology and is compatible with the industry-standard MCS-51 instruction set. By combining a versatile 8-bit CPU with Flash on a monolithic chip, the Atmel AT89C2051 is a power-ful microcomputer which provides a highly-flexible and cost-effective solution to our applications. so application AT89C2051 is used to design a convenient, simple digital display with capacitive measuring instruments. Capacitance of the parameters in the course of testing can be changed at any time, after commissioning shows that the capacitors have been designed for measuring the performance and structure of both standards, the use of a certain value.
