EEPROM from Atmel : 688 - Page 35

EEPROM (Electrically Erasable Programmable Read-Only Memory) is a type of non-volatile memory used to store small amounts of data that must be preserved when power is lost. It is commonly used in computers, microcontrollers, and consumer electronics for firmware storage, configurations, and calibration data.

Leading manufacturers such as Microchip Technology, STMicroelectronics, and Atmel offer a variety of EEPROM solutions tailored to different needs. These components range from byte-erasable to page-erasable versions, providing flexibility in design.

When choosing EEPROM, factors such as memory density, write cycles, and interface type (such as I2C or SPI) are crucial. High-quality EEPROM ensures reliable data retention and integrity, even in harsh operating conditions.
