What is the PIC Microcontroller?
PIC Microcontroller which means Peripheral Interface Controller. PIC Microcontroller is originally developed by General Instrument's Microelectronics Division.
What is the function of EA pin in 8051 Microcontroller?
making EA pin high(i.e connecting it to +5V) means that microcontroller should look for the code in its internal memory. while making it low(i.e connecting it to GND) means that microcontroller should look for the code in the memory which is externally connected by the user. so when there is no external memory connected, simply tie EA pin to +5V supply.
What is 89c51 microcontroller?
89c51 is an microcontroller of 8051 series it is an 8-bit device packed in 40-pin package.
What are the Advantages of at89c52 microcontroller over 8051 microcontroller?
The at89c52 are ones that are more advanced. This means that they are programmable compared to the 8051 which is not. So this makes a really big difference.
How is the microcontroller used for the traffic light control application?
In a traffic light control application, a microcontroller is used to manage the timing and sequence of the traffic lights at an intersection. It processes input from sensors or timers to determine when to change the lights, ensuring safe and efficient traffic flow. The microcontroller executes programmed logic to switch the lights from red to green to yellow, while also coordinating pedestrian signals if needed. By implementing these functions, the microcontroller enhances road safety and optimizes traffic management.
In at89c51 microcontroller what representc C?
CMOS
What is the function of at89c51?
AT89C51 function
Is AT89C51 is already programmed when you buy it from market?
No.....You have to program it and upload in the microcontroller
What is the voltage required for the operation of at89c51 microcontroller?
working voltage is 5v regulated dc
How do you burn AT89c51 microcontroller?
You'll need to acquire a programmer board and the application software. The programmer boards typically plug into your PC and you can write an application using the application software, then you can load the application into the microcontroller using the programmer board.
Why use AT89C51 but not others?
89c51 microcontroller is of the series of 8051,one of oldest yet commonly used microcontroller.89c51 have the less complex features then other microcontroller and it is also easily available and cheap in comparison of other microcontrollers.
What is other name of 89c51?
The 89C51 is also known as the AT89C51, which refers to a specific microcontroller from Atmel (now part of Microchip Technology). It is an 8-bit microcontroller based on the Intel 8051 architecture and is commonly used in embedded systems for various applications.
Can at89s52 replace at89c51?
can we replace AT89c51 by AT89s52 but i have c51 code
How much voltage AT89c51 can bear as input?
AT89C51 can have a maximum of 6.6v as input voltage
What is microcontroller 8051?
The 8051 is a microcontroller. It has the MCS-51 core by Intel and was designed for embedded systems in the 1980's. The name of the CMOS version is 80C51. Today the core is still used in microcontrollers from other companies like Atmel, e.g. AT89C51.
What is range of crystal oscillator frequency in ATMEL89C51?
Atmel posts the datasheet for their AT89C51 and other microcontrollers on their website (see link below). That datasheet specifies that the Atmel AT89C51 is operational for an oscillators in the range 24 MHz to 0 Hz (fully static paused). However, during initial flash programming and verification, it requires an oscillator frequency in the range 24 MHz to 3 MHz. That datasheet also answers many other questions you might have about this microcontroller.
Is AT89C51 and 8051 the same?
yes both are same
