In the 8051 microcontroller, the maximum address in the stack is typically 0x07FF, which is the highest addressable location in the internal RAM. However, since the stack grows downwards from the top of the internal RAM, the stack pointer (SP) typically starts at 0x07 and can go down to 0x00. Thus, the effective stack limit is determined by the available internal RAM and the starting point of the stack pointer, which can be set to a maximum of 0x07 in the standard configuration.
What else can I help you with?
In the 8051 what value does the stack pointer contain immediately after reset?
07H
What is the mean by at89c51?
it is a microcontoller ( a version of 8051) At denotes ATMEL company C stands for CMOS 9 stands for flash memory
How much maximum current 8051 microcontroller can bear?
2.4ma
What is the external data memory capacity of 8051 and why?
65536 bytes, because the 8051 family has a 16 bit external address buss.
Who is first invented 8051 microcontroller or 8051 microprocessor?
Intel
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.
Size of stack memory and stack pointer register in 8051 microprocessor?
8 bit
What is the 16 bit register in the 8051?
pc and stack pointer
In the 8051 what value does the stack pointer contain immediately after reset?
07H

How many address lines and data lines there in 8051?
12
What is the maximum data memory capacity of 8051?
The 8051 microcontroller has a maximum data memory capacity of 64 KB, which includes both internal and external RAM. Internally, it has 128 bytes of RAM and can be expanded to utilize external memory through its address bus. The architecture allows for addressing external RAM, but the practical limit often depends on the specific implementation and additional circuit design.
Who is first invented 8051 microcontroller or 8051 microprocessor?
Intel
How many instruction in 8051 microcontroller?
how many interrupts in 8051
Why the name 8051 as 8051?
because i said so thats why
