Is 8051 same as AT89S52?
At89c52 is same like 8051 but manufacturer is Atmel. The flash memory of At89c52 is 8k but the 8051 have 4,k of flash memory. Otherwise both micro functions are same.
What is TCON register?
Timer Control Register (TCON): TCON is another register used to control operations of counter and timers in microcontrollers. It is an 8-bit register wherein four upper bits are responsible for timers and counters and lower bits are responsible for interrupts. Timer Control Register (TCON)
What is use of EA pin?
Pin 31 (EA/ VPP) –
EA stands for External Access input. It is used to enable/disable external memory interfacing. In 8051, EA is connected to Vcc as it comes with on-chip ROM to store programs. For other family members such as 8031 and 8032 in which there is no on-chip ROM, the EA pin is connected to the GND.
What is the difference between at89c51 and AT89S51?
The only difference between the the 89c51 and 89s51 is that the 89s51 and all S series chips can be programmed through both the ISP port and parallel port. But the 89c51 can be programmed only through parallel programmer.
What is AT89S51 microcontroller?
The AT89S51 is a low-power, high-performance CMOS 8-bit microcontroller with 4K 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.
What is the function of reset pin in microcontroller?
The LVD is an optional function which can be selected through option byte and it allows the device to be used without any External Reset circuitry. During a LVD reset, the RESET pin is held low, thus permitting the MCU to reset other devices. After the device is powered on the supply voltage starts increasing.
What is difference between at89c51 and AT89S52?
Their IDE is same only the difference lies in flash memory. AT89S51 has 4 kB flash memory while AT89S52 have 8 kB flash memory.
What does TMOD mean?
Telecommunications and Mission Operations Directorate.
How many registers register in TCON?
They are 16-bit registers. we give our time delays in it. since 8051 is an 8-bit micro controller, we access its register in two bytes one byte for TH(timer high byte) and one for TL(timer low byte).
How many pins are in microcontroller?
A typical microcontroller can have between 6 and 60 pins on it, to which you’re expected to attach power connections, input and output connections, and communications connections. Every microcontroller has different configurations for its pins, and often one pin will have more than one function.
What is difference between at89s51 and AT89S52?
different between at89s51 and at89s52
89S52 is ISP programmable. You can use a simple parallel port programmer to flash it.
What is the difference between at89c51 and At89c52?
The difference between these Microcontroller are RAM Memory and flash memory. All have the same pin configuration and there is very slight difference between them. 89c51 has 128 bytes of ram while 89c52 has 256 bytes.
What is difference between AT89S51 and at89c51?
What is a reset circuit?
A power-on reset (PoR) is a circuit that provides a predictable, regulated voltage to a microprocessor or microcontroller with the initial application of power. The PoR system ensures that the microprocessor or microcontroller will start in the same condition every time that it is powered up.
Why do we use reset?
In a computer or data transmission system, a reset clears any pending errors or events and brings a system to normal condition or an initial state, usually in a controlled manner.
