What is the architecture of microcontroller?
All MCs use one of two basic design models: Harvard Architecture and von-Neumann architecture. They represent two different ways of exchanging data between CPU and memory. MCs with Harvard architecture are called “RISC MCs”. MCs with von- Neumann’s architecture are called ‘CISC microcontrollers’.
What are the different blocks of architecture of 8051 Microcontroller?
The block diagram of the 8051 Microcontroller Architecture shows that 8051 Microcontroller consists of a CPU, RAM (SFRs and Data Memory), Flash (EEPROM), I/O Ports and control logic for communication between the peripherals.
Which type of architecture 8051 has?
8051 Microcontroller Architecture and Block Diagram with Applications. The 8051 Microcontroller is one of the basic type of microcontroller, designed by Intel in 1980’s. This microcontroller was based on Harvard Architecture and developed primarily for use in embedded systems technology.
What is the architecture of 8051?
8051 microcontroller is designed by Intel in 1981. It is an 8-bit microcontroller. It is built with 40 pins DIP (dual inline package), 4kb of ROM storage and 128 bytes of RAM storage, 2 16-bit timers. It consists of are four parallel 8-bit ports, which are programmable as well as addressable as per the requirement.
How many counters are there in 8051 internal architecture Mcq?
Explanation: The architecture of 8051 consists of 4 latches and driver pairs are allotted to each of the four on-chip I/O ports. It contains two 16-bit timer registers.
Why interrupts are used in microcontroller explain the architecture of 8051 micro controller?
Interrupts provide a method to postpone or delay the current process, performs a sub-routine task and then restart the standard program again. Types of interrupt in 8051 Microcontroller: Let’s see the five sources of interrupts in 8051 Microcontroller: Timer 0 overflow interrupt – TF0.
