What is the use of AT89S52 microcontroller?
The on-chip flash allows the program memory to be reprogrammed in-system or by a conventional non-volatile memory programmer. By combining a versatile 8-bit CPU with in-system programmable flash on a monolithic chip, the AT89S52-24PU is a powerful microcontroller which provides a highly-flexible.
What is AT89S52 controller?
Description. The AT89S52 is a low-power, high-performance CMOS 8-bit microcontroller with 8K bytes of in-system programmable Flash memory. The device is manufactured using Atmel’s high-density nonvolatile memory technology and is compatible with the indus- try-standard 80C51 instruction set and pinout.
How many timers are available in AT89S51?
The AT89S51 provides the following standard features: 4K bytes of Flash, 128 bytes of RAM, 32 I/O lines, Watchdog timer, two data pointers, two 16-bit timer/counters, a five-vector two-level interrupt architecture, a full duplex serial port, on-chip oscillator, and clock circuitry.
How many timers are available in AT89S52?
The AT89S52 provides the following standard features: 8K bytes of Flash, 256 bytes of RAM, 32 I/O lines, Watchdog timer, two data pointers, three 16-bit timer/counters, a six-vector two-level interrupt architecture, a full duplex serial port, on-chip oscillator, and clock circuitry.

How do I load a hex file in AT89S52?
- Select the UsbAsp programmer from the dropdown as shown below.
- Select the AT89S52 controller from the drop down.
- Check the write option to flash the . hex file to the controller.
What is the function of microcontroller?
Microcontrollers are embedded inside devices to control the actions and features of a product. Hence, they can also be referred to as embedded controllers. They run one specific program and are dedicated to a single task. They are low power devices with dedicated input devices and small LED or LCD display outputs.
How many number of register are there in the timer?
In Intel 8051, there are two 16-bit timer registers. These registers are known as Timer0 andTimer1. The timer registers can be used in two modes. These modes areTimer mode and the Counter mode.
Where is the Fout on the LM331 frequency converter?
A special configuration of the LM331 IC performs this conversion. Interestingly, this same IC also performs the FTV conversion as shown in the previous pages of this article. In the VTF configuration, the input voltage “VIN” feeds pin 7, and a proportional frequency “fOUT” appears at the output pin 3.
How many pins does an at89s52 microcontroller have?
Like other microcontrollers, It has GPIO pins, three 16-bit timers, one full-duplex UART communication port, three 16-bit general-purpose timers, on-chip oscillator. Furthermore, it has 40 pins, out of which 32 are GPIO pins. AT89S52 also has an inbuilt Watchdog timer to operate microcontroller low power mode.
What are the power modes of Atmel at89s52?
AT89S52 has two power modes, i.e., idle mode in which stops processing unit stops while other peripheral keep working and power-down mode that halts oscillator and other functions and save RAM contents. Different software and compilers available in the market can be used to program Atmel microcontrollers family.
How many I / O pins does a microcontroller have?
It has 32 I/O pins comprising of three 16-bit timers, external interrupts, full-duplex serial port, on-chip oscillator and clock circuitry. The Microcontroller also has Operating mode, Idle Mode and Power down mode which makes it suitable for battery operated applications.
