What is external memory interface in 8051 microcontroller?
External addressable ROM for the 8051 is of 128KB of address space which is be divided into two parts: Program Code Space. Data Memory Space.3 jui. 2020How to access external memory in 8051?
In 8051 micro controller have in built RAM and ROM,but size of this memory is limited size of RAM is 128 byte while size of ROM is 4KB some time we need more memory then this so we connect external memory with micro controller. To access external RAM we used MOVX instruction.What is external memory interfacing?
The External Memory Interface (often refered to as Port A) provides a versatile interface to external memory, allowing economical connection with fast memories/devices, slow memories/devices, and multiple bus master systems. The external memory interface has two power-reduction features.- External Memory Microcontroller: When an embedded system has a microcontroller unit that has not all the functional blocks available on a chip is called an external memory microcontroller. For example, 8031 has no program memory on the chip is an external memory microcontroller.
