Memory is essential to computer behavior, involving the storing and retrieving of data. One such memory device is the NM93C46EM, known as a serial EEPROM chip. It is used in anything from consumer electronics to industrial control systems. This brief article will identify the application fields and explain the working principle of this particular chip.

Fields of Application

The NM93C46EM chip is designed for a variety of memory-related applications, such as:

• Data storage, such as in non-volatile RAM or FRAM
• Security features, including encrypted data
• Automatic configuration data loading
• Parameterization of electronic systems
• Use in computers, servers and telecommunications systems
• Data logging and analysis

Working Principle

The NM93C46EM chip is a Serial Electrically Erasable Programmable Read-Only Memory device, known as a “SEEPOM”. It is powered by an 8-bit microcontroller, enabling an 8-bit parallel parallel data transmission or an 8-bit byte serial data transmission. The chip is equipped with 4 kilobytes of EEPROM memory. Thanks to an on-chip clock generator, unlike similar memory devices, the NM93C46EM supports a wide range of devices, from quartz timers to crystal oscillators and programmable clock devices.

The working principle of the NM93C46EM is based on a write-once/read-many type of memory technology. In other words, data written to the EEPROM can only be changed after erasing the entire memory. The chip works like a regular EEPROM, in that it requires one EMS cycle to write while an EMS cycle is the equivalent of multiple erase/write cycles. Thanks to a number of features, such as the "end of data" flag and a powerful error correction system, the NM93C46EM provides outstanding reliability and performance in a number of different applications.

Conclusion

The NM93C46EM is a specialized EEPROM chip that is used in a wide variety of memory related applications, from security to data storage. It works on the basis of a write-once/read-many principle and is powered by an 8-bit microcontroller, enabling an 8-bit parallel or serial data transmission. Thanks to its multitude of features, such as the "end of data" flag and an error correction system, it provides reliability and performance in a number of different applications.
