What is 89s52 microcontroller?

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 IO pins are available in AT89S52?

AT89S52 Microcontroller Introduction This device offers 32 GPIO pins which can be used as digital input-output pins or also same pins can be used for alternate functions.

What is atmega328 microcontroller?

The ATMEGA328P-PN is a popular microcontroller due to it being a major component in the Arduino board products. The ATMEGA328P-PN is the 8-bit RISC heart of the Arduino Uno and Nano, with a maximum clock frequency of 20MHz, 32KB program FLASH, and 2KB of RAM.

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.

Which microcontroller has 8k Flash memory?

Program Memory (ROM) of 8051 Microcontroller Almost all modern 8051 Microcontrollers, like 8052 Series, have 8KB of Internal Program Memory (ROM) in the form of Flash Memory (ROM) and provide the option of reprogramming the memory.

What is difference between 89c51 and 89s52?

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.

How can I program my AT89S52 microcontroller without Arduino?

AT89S52 is an old microcontroller so and it does not require a bootloader like Arduino board, so you have to create a hex file of your sketch and you can upload this hex file on AT89S52 chip using AT89S52 SPI programmer Application. You can download the AT89S52 Programmer application by the link given below.
