FM93C66N is a kind of memory that comprises of MicroWire series EEPROM memory, developed by NXP. It is a non-volatile (NV) 8-pin microcontroller that utilizes an auto-addressing protocol that enables seamless fail-safe communications between low-speed microcontrollers and external memory.

The FM93C66N is a 2K-bit (256 bytes) memory device. It contains two separate memory zones, each with 32 bytes, which are known as \'Access Zones\' and are protected by a Write Enable (WE) input. This is used to enable or disable the write operation in the Access Zone. The device also features control logic that allows data in the protected zone to be written only when the reading and writing functions are operated at the same time.

The FM93C66N features true low-voltage operation, allowing it to be used in extreme environmental conditions. It operates at different supply voltage levels (from zero to five volts), and is therefore suitable for a wide range of applications. The device is fully-integrated and it has a self-timed and self-protected write cycle, which ensures that the write time and write protection are optimized for the application.

The FM93C66N also has a dedicated erase/write control (E/W) pin that provides improved control of the write/erase operations and a dedicated temperature sensor to determine the actual ambient temperature. The device also includes a Write Protect (WP) feature, which prevents accidental or unauthorized writes or erasures.

The FM93C66N is popularly used in automotive applications, such as anti-theft systems, body ECUs, and sub-systems. It is also popularly used in industrial applications, such as in sensor systems, programmable logic controllers (PLCs), and Human Machine Interface (HMI) controllers. The device is also commonly used in consumer products, such as POS terminals, handheld information devices, games consoles, and cellular phones.

The FM93C66N\'s working principle is based on a data storage principle called \'Anti-Fuse\'. This technology works by forming a conductive interconnect between a pair of serially coupled electrodes. The electrode pair is separated by a dielectric material, which is usually resistive. The dielectric material is carefully selected to ensure that it is the same resistance as the conduction path between the electrodes, thus providing perfect data retention in both the write and read operations.

When the FM93C66N is operated, it provides an automatic addressing protocol, which allows low-speed microcontrollers to easily and fail-safely access the memory locations. The addressing protocol can be selected with the help of the value stored in the memory locations. This provides an easy and efficient method of communication between the controller and the memory device.

The FM93C66N is an extremely reliable memory device and is suitable for use in a wide range of applications. Its low-voltage operation, dedicated erase/write control, temperature sensor, and write protect feature make it suitable for use in extreme environmental conditions and for a variety of applications.
