The Use of Microsoft Excel to Simulate the Charging Capacitor (C) through a Resistance (R), and Calculating the Appropriate Value of Τ (RC) of 8051 Microcontroller Reset Circuit

On this occasion, the author would like to discuss the use of Microsoft Excel to simulate the charging of the capacitor (C) through a resistance (R) of the 8051 microcontroller reset circuits [1]. The author would also shows the equation (rule of thumb) to calculate the appropriate value of τ (RC) used to form the 8051 microprocessor reset circuit and using the table and the graph obtained from Microsoft Excel to opt the proper RC value.
