What is the family for which AT89S52 belongs to?
The Atmel AT89S52 is a microcontroller in the 80C51 family.
What is the operating frequency of at89s52?
The AT89S52 microcontroller operates at a frequency of 12 MHz.
Interfacing diagram of 74HC245 buffer with AT89S52 microcontroller?
The interfacing diagram of the 74HC245 buffer with the AT89S52 microcontroller typically involves connecting the data pins (A0-A7) of the 74HC245 to the microcontroller's port pins (e.g., P0.0 to P0.7) for bidirectional data transfer. The direction control pin (DIR) of the 74HC245 is connected to a microcontroller pin to determine the data flow direction, with logic high for transmitting data from the microcontroller to external devices and logic low for receiving data. Additionally, the 74HC245's enable pins (G1 and G2) are connected to logic high to activate the buffer. Proper power supply and grounding are essential for both the microcontroller and the buffer for reliable operation.
Why external pull up resistor is needed at port 0 for AT89S52 microcontroller?
To limit the amount of current to the ports
What is the use of AT89S52 in DTMF based industrial aplliances control system?
AT89S52 is a microcontroller based on the Intel 8051 architecture and features. Concerning your question, AT89S52 is the heart of most project involving Dual Tone Multi Frequency (DTMF), that is to say it is the controller IC used in such project.
Can at89s52 replace at89c51?
can we replace AT89c51 by AT89s52 but i have c51 code
What micro controller can be used for 6 sensor inputs?
It depends on the interfaces for the sensors. 1-wire would only need 1 wire, so if you have 10 i/o pins you could have 10 sensors. Its probably I2C, so for 6 sensors you'd need at least 12 I/O pins. Providing you have enough I/O pins on the Microcontroller you can use ANY Microcontroller available.
Why ULN2803 is not directly connected to a relay why it is connected to a relay via microcontroller?
You actually have that reversed. A microcontroller is connected to a relay via a ULN2803 (or other power device driver IC) because the output pins of the microcontroller can't drive relays. The ULN2803 darlington transistors provide the power amplification and the inductive kickback protection needed to drive the relay while only lightly loading the microprocessor output pins.
How many user input and output ports are available on a pic16f88?
The PIC16F88 microcontroller has a total of 13 I/O pins that can be configured as user input or output ports. These pins are grouped into Port A, Port B, and Port C, with Port A having 6 pins, Port B having 8 pins, and Port C having 4 pins. However, the exact number of usable I/O pins can depend on the specific configuration and function requirements of the application.
