NM93C46LZN is a nonvolatile memory from STMicroelectronics that is used in many industrial and consumer applications. It is a single-contact integrated circuit (IC) memory device that can store up to 128 bits of data in 16 8-bit sections. It is used in a variety of applications, such as in memory for embedded systems, for the control of lighting, for control of temperature, and for other applications where nonvolatile storage of data is needed.The NM93C46LZN is a serial EEPROM (Electrically Erasable Programmable Read-Only Memory) that has both Internal and External Address and Data Bus Interfaces. The Internal Interface provides an 8-bit serial data input/output that is controlled by 8-bit write and read pulses. The External Address and Data Bus Interface is an 8-bit input/output data bus. This bus can be used to communicate directly with the processor in systems that require fast read and write speeds.The NM93C46LZN has a write cycle endurance of 2 million cycles, and the data remains stored over a wide temperature range. It is designed to operate over the temperature range of -40°C to +125°C, making it an ideal choice for use in applications where extreme temperatures are encountered.The NM93C46LZN utilizes a two-wire serial interface and has several options for programming data. It allows for a fast read and write operation, with a full write cycle of 4 ms. It also provides an easy way to access the data with its external bus interface.The NM93C46LZN uses an Electrically Erasable Programmable Read-Only Memory (EEPROM) for data storage. EEPROMs are Nonvolatile memory cells that retain their stored information even when power is removed. This type of memory is ideal for applications that require data to be stored over long periods of time and survives a power failure.NM93C46LZN devices have both Page Write and Sequential Write modes. When used in Page Mode, the 8-bit data is written to the selected pages of the device. The page size can be determined by the user. In Sequential Mode, the content of the memory can be written one byte at a time or up to 8 bytes with a single write instruction.The NM93C46LZN is also suitable for use in security applications as it supports a range of security features. These include hardware write protection locks, write protection passwords, and ID-codes for automatic recognition of the device.In summary, the NM93C46LZN is a low-cost, low-power nonvolatile memory device that is suitable for a range of embedded and consumer applications. It has a write cycle endurance of 2 million cycles, allows for fast read and write operations, and provides a wide range of security features.
