Memory: CAT93C66VI-GT3 Application Field and Working Principle

The CAT93C66VI-GT3 is a 16Kb EEPROM and is classified as part of the code array family of memory IC\'s manufactured by Atmel. It is a popular choice to use in electronic applications that require non-volatile data storage. This article explains the main features and advantages of this memory chip, along with its main application field and working principle.

Features and Advantages of CAT93C66VI-GT3

The CAT93C66VI-GT3 can be programmed to store up to 16Kb of data and is available in an 8-pin DIL package. It is based on EEPROM technology which allows for quick data write times of 0.5ms and read times of 20ms. This memory chip is highly rugged and is tolerant to temperatures ranging from -50°C up to 85°C, making it suitable for a wide range of electronic applications. Additionally, the CAT93C66VI-GT3 utilizes Atmel’s proprietary security features, including Sequential Program/Erase Lock Bits, Passwords and Write Protection Bits, meaning it’s suited for secure data storage applications.

Application Fields of CAT93C66VI-GT3

Due to its versatile and robust design, the CAT93C66VI-GT3 has many industry applications, with the most common being in automotive, medical, telecommunications, audio and security devices. The CAT93C66VI-GT3 is also suited to low power, battery-powered devices, since it only requires a limited power supply and so does not result in overheating of the device being driven. It is also used for storing product serial numbers, in conjunction with product life cycle data, as it offers excellent data retention even when power is not connected.

Working Principle of CAT93C66VI-GT3

When data needs to be stored in the CAT93C66VI-GT3, a top electrode layer of chrome-molybdenum is set to a positive voltage and a voltage of a few volts is applied to gate electrodes which separates the resistive layers below. This causes electrons to be attracted to the positive side, creating a charge which is then stored in the device as data. To program the device with data, the electrons are pulled away from the positive side using an eraser current to create an uncharged condition. The electrons can also be moved back and forth to program the memory. The CAT93C66VI-GT3 offers low voltage programming and fast write and read times, making it an attractive choice for data storage in applications that require long-term stability.

Conclusion

The CAT93C66VI-GT3 is an ideal storage solution for many electrical and electronic applications, due to its versatile package, low power consumption and robust design. Its data security features make it well-suited to secure data storage, while its fast read and write times make it suitable for applications requiring frequent data writing and retrieval. In summary, the CAT93C66VI-GT3 is a great choice for memory chip applications, particularly where rapid data write and read operations are required.
