80 - mos technology (chip is based on mos tech.).
5- intrrupts.
1- serial port.
from Ravi ece final year.
The at89c52 are ones that are more advanced. This means that they are programmable compared to the 8051 which is not. So this makes a really big difference.
Intel
how many interrupts in 8051
The 8051 Microcontroller is a microcontroller ("chip") developed by Intel in 1980.
The 8051 runs on +5vdc.
8051 family
Because its a microcontroller with an 8 bit data bus width.
Port 0 is called true bidirectional port.............. swapneel
yes
avr is high speed cmpar to 8051.in 8051 there are less number of instructions
