Because it is 8- 8-bit controller (8000 series)
5- It has 5 interrupts
1- It has only one serial communication port
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.
yes
Port 0 is called true bidirectional port.............. swapneel
avr is high speed cmpar to 8051.in 8051 there are less number of instructions
