93C66CT-E/ST

Introduction

93C66CT-E/ST is a highly integrated serial-in/serial-out integrated circuit memory stored in an 8-pin surface mount package. This memory circuit, manufactured by STMicroelectronics is rather unique in that it utilizes electrically erasable programmable read-only memory (EEPROM) technology. This technology allows the user to program, erase and reprogram the device without the need for any special equipment or tools. This makes 93C66CT-E/ST an ideal choice for applications which require frequent changes in stored data.

Application Field

The 93C66CT-E/ST can be used in a variety of applications including automotive, medical, telecommunications, and industrial control. This highly versatile memory chip can be used to store data such as vehicle mileage, medical history, energy consumption and industrial settings. Some of the more complex applications include controlling vehicle access protection systems, processing patient data, storing mobile phone settings and monitoring environmental conditions.

Working Principle

The 93C66CT-E/ST is based on the EEPROM technology and its principle operation is simple yet effective. To program, erase and reprogram this device, the user simply needs to provide a 5V supply to the chip. This 5V supply causes electrons from the silicon die layer to tunnel through an oxide layer to the positive and negative electrodes where it is then stored for later retrieval. The actual density of the chip can range from 2Kb to 16Kb in increments of 8Kb.

When the device is used to store data, the user must provide a serial input signal. This signal is then compared with the stored data to determine whether the data is correct. If the data is correct then the memory stores the data in its internal EEPROM cells. If the data is incorrect then the memory returns an error signal.

When the user wants to retrieve data, the device requires an additional source of power such as a 5V supply. This allows electrons to be again tunneled through the oxide layer from the positive electrode to the silicon die layer. This process allows the memory to read and return the stored data.

Conclusion

The 93C66CT-E/ST is a highly versatile memory circuit which utilizes EEPROM technology. It offers a wide range of application possibilities and can be used for a range of complex applications such as industrial control, telecommunications, and medical data processing. Furthermore, its ability to be erased and reprogrammed without the need for any special equipment makes it an ideal choice for applications that require frequent changes in stored data.
