Shortly, RAM is used to store variable during program execution, while the EEPROM memory is used to store the program itself, that’s why it is often referred to as the ‘program memory’. Back to home page.
Microcontroller AT89S52 Description – Telecommunication and Electronics Projects
These type of crystals used in almost every modern digital equipment like in computers, watches etc. Pin 31 EA is connected to Vcc, which is an active low pin. Sign in for checkout Check out as guest. Have one to sell? Crystal oscillator is used to generate clock pulses, and clock pulse is used to provide the mean for timing calculation, which is mandatory to synchronise all the events.
It resets the microcontroller when connected to HIGH.
