The 8051 is a microcontroller. It has the MCS-51 core by Intel and was designed for embedded systems in the 1980's. The name of the CMOS version is 80C51. Today the core is still used in microcontrollers from other companies like Atmel, e.g. AT89C51.
The original Intel 8051 was one of a series of single-chip microcontrollers developed by Intel in 1980 for use in embedded systems.
we can use both timers ...
8051 MICROCONTROLLER has no in built A/D Converters but PIC has it. 8051 MICROCONTROLLER based on CISC architectuture while PIC based on RISC archirecture. 8051 has 250 instruction which take 1 to 4 machine cycle to execute while PIC has nearly 40 instruction
Yes, standard 8051 chips have plenty of I/O, their speed is comprehensive and the code size for an elevator controller don't have to be excessive. Check the local legal requirements if you want to use this in a live environment, additional (hardware) security measures may be required. You may wish to look into the PIC family of chips also. Very inexpensive, fast and easy to program and mass produce. Personally, I love these guys for a bunch of applications.
An elevator is an electronic device that transports people or goods in a vertical motion. A microcontroller embedded in the control system of an elevator is used to control the elevator's mechanisms.

how many interrupts in 8051
The 8051 Microcontroller is a microcontroller ("chip") developed by Intel in 1980.
The 8051 runs on +5vdc.
8051 family
yes
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.
avr is high speed cmpar to 8051.in 8051 there are less number of instructions

You will need a 8051 device programmer that connect to a PC with software to drive the programmer
89c51 is an microcontroller of 8051 series it is an 8-bit device packed in 40-pin package.
