The CAT93C66VP2I-GT3 is a non-volatile serial EEPROM from the Memory family. It is typically used as an electrically erasable programmable memory (EEPROM), often for storing settings and parameters for electrical devices, and for its high immunity to electrical noise and available with Extended OEM / ODM customization.

Application field

The CAT93C66VP2I-GT3 is choosen in numerous applications like PCs, embedded system, printers and other electronic devices that need non-volatile memory. In particular it is often selected for its benefits in terms of compatibility with popular standards, extended memory size and design customization. In addition to its flexibility, the device offers impressive technical characteristics like fast program/erase time, Enhanced Data Protection and High Access Rate.

Working principle

The CAT93C66VP2I-GT3 is an 8-pin device with an 8-byte data storage. Its principle is based on the Fowler-Nordheim tunneling effect which is activated by applying a voltage of around 12V on the control pin, while the target pin is grounded. The charge is trapped at the oxide/floating gate interface, resulting in the alteration of the threshold voltage of the device. When the device is in read mode, the threshold voltage detection circuit senses the correct voltage level and returns the logic level according to the binary state of the memory.

By using the same principle, the device is able to erase the data by applying a higher voltage of more than 20V on the control pin, while the target pin is grounded. This action transports the charges from the floating gates and clears the memory, allowing it to be programmed without errors.

Conclusion

The CAT93C66VP2I-GT3 is a versatile and reliable electrical memory solution for a wide range of applications. Its non-volatile design, compatibility with various standards, Extended OEM / ODM customization and robust electrical characteristics make it the ideal choice for embedded systems, PCs, printers, and other electronic devices that need non-volatile memory.
