ON Semiconductor CAT93C66VI-GT3 Microchip

The CAT93C66VI-GT3 is a high-performance, 4K-bit serial EEPROM memory chip from ON Semiconductor, renowned for its reliability and ease of use. This device is part of the CAT93Cxx family, which provides designers with a range of storage solutions for various applications.

Designed with a versatile serial interface, the CAT93C66VI-GT3 supports the standard 3-wire serial communication protocol, making it compatible with a wide array of microcontrollers and digital systems. Its 4K-bit memory is organized as either 256 x 16-bit (word) or 512 x 8-bit (byte) selectable by the user, offering flexibility in data storage and retrieval.

The EEPROM operates over a voltage range of 2.5V to 5.5V, making it suitable for low-power operations and compatible with 5V systems. This feature, combined with a low active current and standby current, makes the CAT93C66VI-GT3 an energy-efficient choice for battery-powered devices.

One of the key advantages of this EEPROM is its endurance, with the capability to withstand over 1,000,000 program/erase cycles and a data retention period of over 100 years. This ensures long-term reliability of the data stored, which is crucial for applications that require frequent data updates and longevity.

The CAT93C66VI-GT3 comes in a compact 8-pin TSSOP package, which is ideal for space-constrained applications. It also features a self-timed write cycle with auto-clear, simplifying the write operation and reducing the need for external timing management. The device includes a write protection mechanism to prevent inadvertent data alteration during power transitions.

Common applications for the CAT93C66VI-GT3 include industrial controls, medical devices, automotive systems, and consumer electronics where non-volatile memory is required. With its robust design and ON Semiconductor's commitment to quality, this EEPROM is a dependable choice for engineers and designers looking to incorporate stable and efficient memory solutions into their products.
