What is the external data memory capacity of 8051 and why?
65536 bytes, because the 8051 family has a 16 bit external address buss.
What is psen pin in 8051?
Program Store Enable: The read strobe to external program memory.
What is 8051 loader?
The Loader is a program that moves the executable file produced by linker from the secondary storage device to memory for execution
How much maximum current 8051 microcontroller can bear?
2.4ma
What is difference between 89s52 and 8051?
internal and external memory
Explain about pin diagram of 8051 micro controller?
The microcontrollers have an 8-bit data bus. They are capable of addressing 64K of program memory and a separate 64K of data memory. The 8051 has 4K of code memory implemented as on-chip Read Only Memory (ROM). The 8051 has 128 bytes of internal Random Access Memory (RAM). The 8051 has two timer/counters, a serial port, 4 general purpose parallel input/output ports, and interrupt control logic with five sources of interrupts. Besides internal RAM, the 8051 has various Special Function Registers (SFR), which are the control and data registers for on-chip facilities. The SFRs also include the accumulator, the B register, and the Program Status Word (PSW), which contains the CPU flags. << SHARMILA TANDEL (B.E) ELECTRONICS >>
What is RAM memory space allocation 8051?
Sorry sir i don't no.
Size of stack memory and stack pointer register in 8051 microprocessor?
8 bit
Program to convert bcd to gray code using 8051 microcontroller.?
66666
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.
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.
Write a program to add two 8 bit numbers in microprocessor 8051?
write it in 8085
