Intel 8051 provides _____ interrupt structures and 8052 provides _____ interrupt structures.

Correct option is A

The correct answer is (A) 6; 7.

Explanation:

The Intel 8051 microcontroller supports 6 interrupt sources, while the enhanced Intel 8052 microcontroller includes 7 interrupt sources, offering more flexibility and control in real-time embedded applications.

Information Booster:

• 8051 Interrupts:

  • Total Interrupt Sources: 6

  • Includes: External Interrupt 0 (INT0), Timer 0, External Interrupt 1 (INT1), Timer 1, Serial Communication, and a general interrupt control mechanism.

  • Vector locations are fixed in ROM, allowing efficient interrupt handling.

• 8052 Interrupts:

  • Total Interrupt Sources: 7

  • All 8051 interrupts plus one additional interrupt from Timer 2.

  • Used in more advanced embedded systems requiring precise timing control and multiple interrupt levels.
