Question
The 8051 microcontroller has __________ on-chip RAM and __________ on-chip ROM.
The correct answer is
128 bytes, 4 K bytes
8051 Microcontroller On-Chip Memory
The standard architecture of the 8051 microcontroller includes specific amounts of built-in RAM and ROM.
- On-Chip RAM: The 8051 features 128 bytes of internal Random Access Memory (RAM), used for data storage and the stack.
- On-Chip ROM: It also contains 4 K bytes (which is 4096 bytes) of internal Read-Only Memory (ROM), typically used for storing the program code.
Therefore, the 8051 microcontroller has 128 bytes on-chip RAM and 4 K bytes on-chip ROM.
