93C66-E/P

93C66-E/P memory is an intermediate memory device that offers a variety of features to meet the requirements of today\'s embedded applications. It is a OTP (one time programmable) memory device from Microchip, that can be used in a variety of applications such as programing, data storage and identification. It is a EEPROM device that is designed for applications such as data protection, program confidentiality, validation and authentication.

The memory device employs an 8-bit architecture with a 20-byte page register, allowing read and write operations. Additionally, it incorporates an 11-byte security register that provides additional features such as software lock, write protection, and data protection.

The memory device is typically used in system and embedded applications. The device is suitable for a range of memory intensive applications such as industrial control systems, consumer electronics, medical instruments and automotive systems, among others. In addition, the device is also intended for applications that require extreme durability, such as in remote medical controllers.

The 93C66-E/P memory device has an 8-bit data bus interface and can be programmed using the industry standard 8051 microcontroller interface. In addition, the device features security features like an external and internal control register, which can be used to protect read and write operations. The memory device also features a write protect pin that is used to inhibit program and data write operations. This pin can also be used to program the memory device.

When programming the device, a 9-bit command and address must be written to the device followed by the data. The data is written to the page register and is stored on the chip until a new write operation. The data can be read from the memory by sending a 9-bit command and address. The data is then retrieved from the page register and read from the device.

The 93C66-E/P memory device also supports an open virtual access which allows for easier programming and data management. This allows for the programming of data directly from the application software. This feature is useful for applications such as system monitoring and data logger. Furthermore, the device provides an internal write protection circuit which prevents accidental overwriting of data.

Overall, the 93C66-E/P memory device is a reliable and efficient memory device that offers a range of features and is suited for a variety of applications. It is a cost-effective solution for applications requiring a non-volatile intermediate memory device with programmer-friendly features.
