The NM93C56EM is a 16kbit microwave or EEPROM device that can be used in storage and memory applications.

This on-chip, non-volatile memory device is ideal for storing parameter information, such as analog and digital settings, and also used for firmware storage in embedded systems. The device can be written and read with either a serial bus or parallel bus, depending on the design needs. The IC features a self-address capability, which allows for easy detection and programming. The communication with the device can take place at various frequencies, from DC-up to 10MHz.

The memory cell array is organized in 16-bit words and the data is retrieved in a serial data format. It can also read from a limited run of serial addresses, which is convenient for scanning data by using a single serial bus. Furthermore, the NM93C56EM is equipped with an automatic program alarm for detecting data corruption, as well as an output enable feature that provides data security against inadvertent programming.

Due to its low-power consumption and robust construction, the NM93C56EM stands out as an ideal storage solution for military and space applications, due to its SEU-tolerant properties and radiation tolerance. The device also offers good data retention and word-write operation, as well as a high-speed write cycle. The device has an extended operating temperature range of -55°C to 85°C. It can also be operated with a 3.0V power supply.

The working principle of the device is based on the charge-coupled-flux capacitor principle. The device uses an oscillatory mechanism to form a charge-coupled flux capacitor that stores the charge in each unit. Each bit is characterized by a different capacitance level, and the capacitance levels of each bit are detected to generate the input data. Additionally, the circuitry in the device is designed to monitor the level of charge stored in the capacitor element.

The device’s charge-transfer rate is controlled by an external clock and the output data is determined by the capacitance levels. This allows for fast read/write operations, creating an ideal solution for applications requiring a high-speed memory interface. The device includes a standby latch circuit to hold the compiled data in its memory while it is not being accessed. Additionally, the NM93C56EM supports a programming verification algorithm.

Overall, the NM93C56EM is an extremely versatile device that can be used in many types of memory applications due to its high-speed data storage capacity, low-power consumption and robust construction. Its SEU tolerance, radiation tolerance and extended temperature range make it ideal for military and space applications. The device’s charge-coupled-flux capacitor principle allows for fast read/write operations and the integrated standby latch circuit provides data retention.
