EEPROM Memory
EEPROM (Electrically Erasable Programmable Read-Only Memory) is a non-volatile memory type commonly used in embedded systems and electronic devices. It allows data to be electrically written and erased, making it ideal for storing configuration settings, calibration data, and small-scale persistent information.
I²C EEPROM – Small Capacity
(1 Kbit–32 Kbit)
Small-capacity I²C EEPROM in DIP-8 or SOIC-8 packages, including models like 24C01/24C02, highly reliable and ideal for microcontroller settings, device identification, and short-term data storage.
I²C EEPROM – Medium Capacity (32 Kbit–512 Kbit)
Medium-capacity I²C EEPROM in SOIC-8 or TSSOP-8 packages, including 24C16/24C32/24C64, perfect for microcontroller configurations, lightweight data logging, and industrial control parameters.
I²C EEPROM – Large Capacity
(512 Kbit–2 Mbit)
Large-capacity I²C EEPROM in TSSOP-8 or WLCSP packages, including AT24CM02/24CM16, suitable for IoT device configurations, firmware upgrades, and high-volume data storage.
SPI EEPROM – Small Capacity
(32 Kbit–128 Kbit)
Small-capacity SPI EEPROM in SOIC-8 or DIP-8 packages, such as 25C32/25C64, ideal for high-speed data caching and short-term log storage.
SPI EEPROM – Medium Capacity
(128 Kbit–512 Kbit)
Medium-capacity SPI EEPROM in SOIC-8 or TSSOP-8 packages, including 25C128/25C256, perfect for firmware storage and industrial control data.
SPI EEPROM – Large Capacity
(512 Kbit–2 Mbit)
Large-capacity SPI EEPROM in SOIC-8 or WSON-8 packages, suitable for consumer electronics data storage and IoT firmware upgrades.
SPI EEPROM – Extra Large Capacity
(2 Mbit and above)
Extra-large-capacity SPI EEPROM in WSON or BGA packages, ideal for high-capacity data storage, large firmware upgrades, and IoT devices.
