Introduction to MAX 232 IC
The MAX 232 device is a dual driver/receiver that includes a capacitive voltage generator to   supply EIA-232 voltage levels from a single 5V supply. The voltage level in the RS232 bus is about 30V. Each receiver converts EIA-232 inputs to 5V TTL/CMOS levels. These receivers have a typical threshold of 1.3V and a typical hysteresis of 0.5 V, and can accept ±30V inputs. Each driver converts TTL/CMOS input levels into EIA-232 levels. It is used in battery-powered systems, Terminals, modems, computer and many other applications. Only one of the driver and receiver is utilized here.

Clock circuit of 8051 The 8051 has on chip oscillator pin XTAL1 and XTAL2 are provided for connecting a resonant network to from an oscillator crystal frequency ranges from 1 MHZ to 24 MHZ. Ceramic resonators may be used as a low-cost alternative to crystal resonators but due to decrease in frequency stability and accuracy, ceramic resonators are not preferred for high-speed serial data communication with other system. The oscillator formed by the crystal, capacitors, and on chip inverter generates pulse train at the frequency of the crystal as shown in fig. The clock frequency & establishes the smallest interval of time within the microcontroller, called the pulse, p, time. The smallest interval of time to accomplish any simple instruction, or part of a complex instruction, however, is the machine cycle. The machine cycle is made up of six states. A state is the basic time interval for discrete operations of the microcontroller such as fetching on encode byte decodin...

8051 reset circuit.  The 8051 has an active high reset input must 0 high for two machine cycle when power is first applied and then goes to low. The simple RC circuit used to supply system voltage(VCC) to the reset pin until the capacitor charge. At a threshold of about 2.5v, the reset input reaches a low level and the system begins to run. The reset button enables the user to reset the system with out having to turn power off and on. 8051, 8051 reset circuit, clock circuit of 8051., mazidi, microcontroller 8051 basics,
