Who is first invented 8051 microcontroller or 8051 microprocessor?
Intel
What is the external data memory capacity of 8051 and why?
65536 bytes, because the 8051 family has a 16 bit external address buss.
Interface of ADC0808 with AT89S52?
check this link http://www.dnatechindia.com/index.php/Tutorials/8051-Tutorial/Interfacing-ADC0808-To-8051.html
Advantages of at89c51 microcontroller over 8051 microcontroller?
the 8051 microcontrroller is the name doesnt matter easy or not....but the maiin and imp diff between both is at89s51 represents the 8051 chip no....along with the name of company i.e atmel, so all n all both are same thing ...... 89c51 have RISC architecture and contains less no of opcodes which are easy for programming. so iti is preferred than 8051.
How do you add and subtract 16 bit numbers using 8051 microprocessor?
The 8051 is a microcontroller, not a microprocessor. To add or subtract, use the ADD or SUBB opcodes.
Which oscillator is used in 8051?
crystal oscilators mostrly of 11.05.... or 12MHz are used with microcontrollers,
Why you use crystal in 8051 microcontroller?
for accurate time rc oscillator is common in non time critical stuff
Why the frequency is 11.059 Hz in 8051 micro-controller?
First let me make you correct it's not 11.059 Hz it's 11.0592 MHz and we select? this crystal because it makes 8051 Microcontroller to be compatible with IBM standard PC(baud rate 9600) to transfer data.
Who is first invented 8051 microcontroller or 8051 microprocessor?
Intel
Why the name 8051 as 8051?
because i said so thats why
How many instruction in 8051 microcontroller?
how many interrupts in 8051
What is the difference between microcontroller 8051 and avr atmega16?
avr is high speed cmpar to 8051.in 8051 there are less number of instructions
How much voltage is required to energize the 8051 microcontroller?
The 8051 runs on +5vdc.
Is 8052 family of 8051?
Yes, 8052 family is upgraded version of 8051 family
What are 8051 based systems?
The 8051 is a micro-controller series, basically a computer on a chip. A system based on the 8051 series micro-controller is simply that, a device or series of devices that operate under control of one or more 8051 micro-controllers.
What is the use of two capacitor with crystal in 8051?
The "requirement" of using two capacitors with the crystal in the 8051 is complicated, and based on many factors, such as series resistance, the design of the parallel resonant feedback circuit, stray or parasitic capacitance, startup stability, etc. Insight can be gained from Intel's Application Note AP-155 but, in the final analysis, from a purely pragmatic standpoint, the requirement is there simply because "Intel says so". Use the circuit from the data sheet.
What is the purpose of 8051 microcontrollers?
8051 Microcontrollers were popular computer chips used in Intel computers throughout the eighties and nineties. Though technology has advanced beyond their common use, they can still often be found in engineering schools as tools used in introductory microcontroller classes.
