Microchip Technology's AT24C02D-STUM-T EEPROM

The AT24C02D-STUM-T is a high-performance, serial electrically erasable and programmable read-only memory (EEPROM) module from the renowned manufacturer Microchip Technology. This device offers a 2-Kbit (256 x 8) memory capacity and utilizes the standard I²C-compatible (2-wire) serial interface, which makes it a versatile choice for a wide array of applications that require data storage that can endure frequent erasing and rewriting cycles.

With its compact 8-pin TSSOP package, the AT24C02D-STUM-T is designed for optimal space-saving on PCBs, making it an ideal solution for applications with limited board real estate. Furthermore, it operates across a voltage range of 1.7V to 5.5V, which allows for compatibility with both traditional 5V systems and newer, lower-power designs that operate at 1.8V. This versatility ensures that the EEPROM can be integrated into various system designs without the need for additional power supply components.

The device boasts a robust data retention period of over 100 years and can support up to one million write/erase cycles, ensuring long-term reliability and data integrity. This makes it suitable for applications that require frequent data updates, such as configuration settings, device calibration data, or user preferences.

Key features of the AT24C02D-STUM-T include:

• 2-Kbit (256 x 8) EEPROM
• I²C-compatible serial interface
• Wide voltage range (1.7V to 5.5V)
• High write endurance with 1 million write cycles
• Long data retention of over 100 years
• 8-pin TSSOP package for space-saving applications
• Internally organized as 256 pages of 8 bytes each
• Write protect pin for hardware data protection

This EEPROM is particularly easy to use thanks to its built-in hardware write protection, which can be activated via the write protect pin. This feature prevents inadvertent data changes, adding an extra layer of security to sensitive data storage.

In summary, the AT24C02D-STUM-T from Microchip Technology is a reliable and flexible non-volatile memory solution that is well-suited for a wide range of applications requiring frequent or long-term data storage. Its robust endurance and retention characteristics, coupled with the convenience of a serial interface and small package size, make it an excellent choice for designers and engineers looking to enhance their systems with a dependable memory component.
