ON Semiconductor CAT34C02HU4I-GT4 - EEPROM Memory

The ON Semiconductor CAT34C02HU4I-GT4 is a high-performance, 2-Kb I²C serial EEPROM (Electrically Erasable Programmable Read-Only Memory) device that offers a robust storage solution for various applications. It is designed to provide a convenient and efficient way to store device configurations, calibration data, and user-specific information that can be preserved between power cycles.

This EEPROM device operates over a voltage range of 1.7V to 5.5V, making it suitable for low-power and standard operations. It is compatible with the standard I²C serial interface, which allows for easy integration into most microcontroller-based systems. The CAT34C02HU4I-GT4 supports a maximum clock frequency of 1 MHz (Fast Mode) and 400 kHz (Standard Mode), providing flexibility in system design.

The CAT34C02HU4I-GT4 is organized as 256 x 8 bits, which provides 2 Kbits (256 bytes) of memory. It features a hardware write-protection pin (WP) to prevent accidental memory changes, ensuring data integrity during critical operations or in harsh operating environments. The self-timed write cycle with auto-clear functionality simplifies the write operation, eliminating the need for complex programming algorithms.

This EEPROM is designed for high reliability and endurance, with the capability to withstand up to 1 million write cycles and a data retention period of 100 years. It is available in a compact, 8-lead TSSOP package, making it ideal for space-constrained applications. The device is specified for operation over the industrial temperature range of -40°C to +85°C, offering stable performance under varying conditions.

ON Semiconductor's CAT34C02HU4I-GT4 is a versatile non-volatile memory option for designers looking to enhance their systems with a reliable storage component. Whether it's for consumer electronics, industrial automation, or automotive applications, this EEPROM can meet the demands of complex and sophisticated electronic systems.
