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 >>
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.
What do you mean by OTP 8051?
OTP 8051 refers to a specific type of microcontroller based on the 8051 architecture, which is programmed using One-Time Programmable (OTP) memory. This means that once the program is written to the chip, it cannot be modified or erased, making it ideal for applications where the code is finalized and will not need updates. OTP 8051 microcontrollers are commonly used in embedded systems for tasks like control, automation, and data processing. Their limited reusability is compensated by their reliability and simplicity in design.
Why 8051 is called 8 bit?
Because its a microcontroller with an 8 bit data bus width.
What is meant by Tmp 1 and Tmp 2 in 8051 microcontroller?
In the context of the 8051 microcontroller, Tmp 1 and Tmp 2 refer to temporary registers or memory locations used during the execution of instructions. These temporary registers are often utilized by the CPU to hold intermediate data or results during arithmetic and logical operations. They help optimize processing by reducing the need to access slower main memory frequently. However, specific naming conventions like Tmp 1 and Tmp 2 may vary, as the 8051 architecture mainly utilizes general-purpose registers for such temporary storage.
How do you use on chip RAM of 8051?
In other words, how do you save temporary data such as data stored in registers r0 to r7 ? The simplest way to use on-chip RAM of the 8051 is to compile your C code with the "--model-small" small memory model option of the SDCC compiler, which tells it to put all variables in on-chip RAM of the 8051.

What device enables a PC to retrieve a specific row of data from system memory and place it on the external data bus?
Memory Controller Chip
What is an example of external data?
External data is something that is added to a device to increase its storage capacity. An example of this would be an SD card that you put in a cell phone.
How do you transfer data directly to external memory in samsung 3310?
magic. and duct tape
How many address lines and data lines there in 8051?
12
How much storage capacity does a computer with 3MB of memory have?
A computer with 3MB of memory storage capacity can be limited. This will be the size of a single photo taken it cannot be useful in terms of data storage.
External fragmentation. Why is it needed?
External fragmentation describes the situation where free memory blocks are scattered throughout the memory space, which can make it challenging to find contiguous blocks of memory for larger programs or data. This can slow down the memory allocation process and waste memory resources. Techniques such as compaction or paging are used to reduce external fragmentation and ensure efficient memory utilization.

The amount of RAM that is actually on the memory modules in your computer is the memory?
The amount of RAM that is physically installed on the memory modules in your computer is known as the memory size or memory capacity. This determines the storage capacity for temporary data storage and retrieval while the computer is running programs. RAM is crucial for system performance as it provides quick access to data for the CPU.
What is user memory for operating system?
A user memory for an operating system are the devices in which data is stored. These devices can be built into the computer, such as the hard drive, or they can be an external device, such as a USB pen drive or external hard drive.
