There are many differences between the 8085 and the 8086/8088. Naming just a few...
- 8085 is an 8 bit processor, while 8086 is a 16 bit processor
- 8085 has a 16 bit address bus, while 8086 has a 20 bit address bus
- 8085 has an 8 bit data bus
- 8088 has an 8 bit data bus
- 8086 has a 16 bit data bus
- 8086 has a segmented architecture to support the 20 bit address bus
- 8086 has additional registers that support string and repeated loop instructions
- 8086 has addition register that support stack frame parameter addressing
- 8086 has more addressing modes, including cross-segment modes
- 8086 has more types of interrupts, including debug single-step
- 8086 has true multiplication and division instructions

Why 8051 is called 8 bit micro controller?
A: Because it can only control 8 bits of data.
Circuit diagram of IR TV remote control using 8051 microcontroller also explain its working?
the 8051 is a micro controller the buttons tell the 8051 to do something there is an ir led on an output bit of the 8051 that shines on the tv ir detector it pulses a code the tv knows or window fan, ac , vcr, dvd the other output bits are used to scan multiple buttons like the difference between a rotary and touch tone Phone ive seen them with tms1000 and z8 thermostats may have 68hc11 it has 8 channel a/d right on it circuit diagram is very trivial its all in how you pulse the led
Differences between Intel 8051 and atmel 89c51 micro controller?
The instructions used by Atmel 89CXX and 89CXXXX are the same or subset of 8051 microcontrollers.Fully static operation,flash program memory,less pin count andprecision analog comparator ( in case of 89C20510)are some of the attractions in going for these microcontrollers. Due to many similar features in the architecture and instruction and instruction set as that of 8051, it becomes possible for the 8051 designer to directly start using 89CXX and 89C20XX microcontrollers without any more efforts in learning these microcontrollers.
How do you connect LCD to microcontroller?
Yes, but you'll need way more detail than you can get from a simple answer. You need: The 8051 micro, an LCD interface the LCD, and software to get the 8051 to drive the LCD. You may be able to find a kit/project that already contains these items.
What are the control signals for 8051 micro controller?
EA - External Access PSEN - Program store Enable ALE - Address Latch Enable RST - Reset WR - RD
