ON Semiconductor CAT24WC04LI EEPROM

The CAT24WC04LI is a high-performance, serial Electrically Erasable Programmable Read-Only Memory (EEPROM) device from ON Semiconductor. This memory module boasts a 4-Kb storage capacity, making it suitable for a wide range of applications that require non-volatile memory storage. It operates on the industry-standard two-wire I<sup>2C serial interface, ensuring compatibility with a vast array of microcontrollers and processors.

Designed with reliability and efficiency in mind, the CAT24WC04LI features a low-power design, which is particularly advantageous for battery-operated devices. Its operating voltage range of 2.5 V to 5.5 V provides flexibility for use in systems with different power supply levels. This EEPROM module is capable of withstanding harsh conditions, with an extended temperature range from -40°C to +85°C, making it suitable for industrial and automotive applications where stability and durability are crucial.

One of the key advantages of the CAT24WC04LI is its byte and page write capabilities, which allow for efficient data management and storage. The device supports a page write buffer of 16 bytes, enabling quick and convenient updates to memory contents. Additionally, the EEPROM features a self-timed write cycle with auto-clear, which simplifies the programming process and reduces software overhead.

The CAT24WC04LI is also designed with data protection in mind. It includes hardware write protection features, such as a write protect pin, that prevent accidental data alteration. Furthermore, the device offers a software write protection mode for enhanced data security, which can be activated through a series of write operations to designated register bits.

Available in a compact 8-pin SOIC package, the CAT24WC04LI is ideal for space-constrained applications. Its small footprint and low-profile design make it a suitable choice for portable electronics, telecommunications, and other embedded systems where physical space is at a premium.

Overall, the CAT24WC04LI from ON Semiconductor represents a robust and versatile non-volatile memory solution that can meet the demands of a variety of applications, from consumer electronics to industrial automation systems.
