EEPROM stands for
The I stands for Indian. The R stands for reserves. The S stands for space.
E stands for electrode, 60 stands for tensile strength, 1 stands for welding positions, and 1 stands for special charcteristics.
"m8s" stands for: mates.
Circle stands for female and square stands for male.
S stands for SEMI CONDUCTOR
can we replace AT89c51 by AT89s52 but i have c51 code
The Atmel AT89S52 is a microcontroller in the 80C51 family.
yes
32
semi conductor
Its an I\O controller
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.
To limit the amount of current to the ports
Short answer is yes. It does require some interface circuitry, which can be found at www.8052.com
