What is AT89C51 microcontroller?

Description. The AT89C51 is a low-power, high-performance CMOS 8-bit microcomputer with 4K bytes of Flash programmable and erasable read only memory (PEROM). The device is manufactured using Atmel’s high-density nonvolatile memory technology and is compatible with the industry-standard MCS-51 instruction set and pinout …

Is 8051 and AT89C51 the same?

both are same and based on 8051 cisc architechture,in AT89c51 ,it doesnot support isp programming feature because these pins like miso,sck,mosi,reset are not available for use,so they are programmed through parallel port programming while s-series of at89s5x contain these feature and easily programmed through these …

What is difference between at89s51 and AT89C51?

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 AT89C52?

The AT89C52 is a low-power, high-performance CMOS 8-bit microcomputer with 8K bytes of Flash programmable and erasable read only memory (PEROM). Due to on-chip Flash, the program memory is programmable in-system or by a conventional non-volatile memory programmer.

What is microcontroller IOL?

Iol stands for current, output low. Currents are traditionally referenced as going into a pin. If the output is high, the current flows out, so it is given a negative number. In some microcontrollers the maximum sink and source current limits for a given pin might be different.

What is the clock source for the timers?

1. What is the clock source for the timers? Explanation: Timer’s clock source is the crystal that is applied to the controller.

What is the difference between 89c52 and 89s52?

AT89s52 is “In-System” programable, u can program simply with your PC, whereas AT89c52 is programmed with the programmer.
