The ROM capacity of the 8051 microcontroller typically ranges from 4 KB to 64 KB, depending on the specific variant and manufacturer. The original 8051 architecture includes a built-in 4 KB of ROM, which is used to store the program code. Additionally, external ROM can be interfaced to expand the memory capacity as needed for specific applications.

What is the external data memory capacity of 8051 and why?
65536 bytes, because the 8051 family has a 16 bit external address buss.
Difference between 8031 8051 and 8751 microcontrollers?
Answer It is both 8 bit processors in a 40 pin package but it is not pin compatible, it have almost the same functions but it is very difficult to compare the two because it is not the same family.
What is the maximum program memory capacity of 8051 Why?
The maximum program memory capacity of the 8051 microcontroller is 64 KB. This limitation arises from its 16-bit address bus, which allows it to address a maximum of (2^{16}) (or 65,536) memory locations. Each memory location corresponds to one byte, hence the 64 KB capacity for program memory. This design constraint is inherent to the architecture of the 8051.
What Is disadvantage of rom?
Memory holding capacity of CD-ROM is less and we can not rewrite the data in to the CD-ROM
High capacity optical disk?
DVD RoM
Is any memory integrated with the processor 8051?
ANSWER The Intel 8051 had integrated RAM, ROM, and various I/O functions. This is typical of microcontrollers. I forget the amounts, probably 4 kB of ROM and 64 bytes of RAM? Newer 8051-compatible microcontrollers have a wide variety of memory and integrated I/O options. (Useless information: the 8051 used 12 oscillator cycles per machine instruction cycle, due to the synchronous way it decoded the instructions, fetched the operands, and stored the results. Newer versions get semi-asynchronous and run the same operands in 4, 3, or even 1 cycle.)
What is capacity of DVD-ROM?
Depends on computer.
What is the storage capacity of a CD-ROM?
The storage capacity of a CD-ROM is:In megabytes(mb):700In bytes(b) :734003200In gigabytes(gb):0.68359375
What is the difference between AT89S52 and AT89C52?
89S52 have 8KB ROM and 256bytes RAM also it supports SPI program downloading but 89C51 have 4Kb ROM, 128bytes RAM and it wont support Serial program downloading. For more details visit www.8051projects.info
