How does eeprom work. To write data to EEPROM, a high voltage is applied to the floating gate electrode. Send the Lea How does EEPROM work? We used the EEPROM 24C02, which has a 2 KB memory capacity, from the circuit to store the necessary password or number entered by the keypad, both of which are interfaced to the microcontroller seen in the figure. Writing a byte of memory to the EEPROM generally happens in three steps: 1. Our example sketch will simply take any byte that comes in over the serial port and write it to the EEPROM, keeping track along the way of how many bytes we've written to memory. It is a type of non-volatile memory that allows data to be stored and retrieved even when power is removed. It is a type of non-volatile memory that can be electrically erased and reprogrammed. A 12MHz crystal is also connected between then pin 18 and 19 to provide the clock for the functioning of Its versatility and non-volatile nature make it indispensable in various applications. It is used in computers, usually integrated in microcontrollers such as smart card s and remote keyless system s, or as a separate chip device, to store relatively small amounts of data by allowing individual bytes to be erased and reprogrammed. Jun 11, 2025 · Introduction to EEPROM EEPROM, or Electrically Erasable Programmable Read-Only Memory, is a type of non-volatile memory that plays a crucial role in the functioning of microprocessors.
