Microchip 24C02CT-I/SN: A High-Performance 2-Wire Serial EEPROM Memory Solution

The Microchip 24C02CT-I/SN is a highly reliable 2-Kbit Electrically Erasable Programmable Read-Only Memory (EEPROM) designed for a broad spectrum of embedded systems and consumer applications. This device utilizes a simple yet powerful 2-wire serial interface, adhering to the widely adopted I²C protocol, making it an ideal choice for applications requiring non-volatile memory with minimal pin count.

Housed in a compact 8-lead SOIC package, this EEPROM is engineered for space-constrained PCB designs. It operates across a standard voltage range of 1.7V to 5.5V, ensuring compatibility with various logic levels and low-power systems. A key feature of this memory chip is its self-timed write cycle, which includes an auto-erase function, simplifying the software overhead for the host microcontroller. With a maximum operating frequency of 400 kHz, it provides sufficient speed for numerous data logging and configuration storage tasks.

The memory array is organized as 256 x 8 (2K) bits, offering byte-level read and write capabilities. This granularity allows for efficient storage of system parameters, calibration data, and user settings. The device also features hardware write protection, enhancing data security by preventing accidental overwrites. Its endurance is rated for 1 million erase/write cycles, and it boasts a data retention period of over 200 years, ensuring long-term reliability.

Typical applications include use in smart meters, automotive systems, industrial controls, networking equipment, and a vast array of Internet of Things (IoT) devices where dependable, non-volatile storage is paramount.
