NM93C56M8 is a 1-Wire, 8Kb serial EEPROM from On Semiconductor, designed for low-power, low-voltage applications. It requires almost no power during read or write cycles, making it a great choice for portable and battery-driven applications. It is also a good choice for embedded systems where sub-microampere current drain is critical.

The NM93C56M8 EEPROM utilizes a single-wire interface, which requires only one port pin for communication. It is available in a tiny 8-pin leadless SOIC package, making it ideal for space-constrained applications. The communication interface is a modified ISO-standard with a 9.6 Kbaud bit rate.

The NM93C56M8 is suitable for a wide range of applications, including low-voltage industrial, automotive, and portable applications. It is ideal for applications that require frequent writes, such as system settings, customized code, or product configuration. It also supports a patented software/firmware authentication process, making it an attractive choice for security-sensitive environments.

The NM93C56M8 consists of 8 Kb of EEPROM memory arranged into sixteen non-volatile pages of 512 bytes each. The memory can be individually accessed and modified, allowing for efficient storage of data and code. Data written to the device is held until specifically changed.

The EEPROM can be operated at power supply voltage from 1.8V to 5.5V. The device allows both random access reads and sequential reads, which can be performed at a maximum rate of up to 333 kbaud. It allows three different write cycles: software, hardware, and bypass programming. Software write cycles allow data to be written to the device one byte at a time, while hardware and bypass programming cycles allow bit-wise access to the device.

The NM93C56M8 EEPROM also features a built-in watchdog timer and an 8-bit in-circuit programmable read/write timer. The watchdog timer has three different operating modes, which can be used to determine when data should be written to a device. The read/write timer allows for the interface speed to be adjusted for various applications. The time select mode allows the device to switch between fast and slow speeds, depending on the amount of data to be sent.

Overall, the NM93C56M8 is an ideal choice for any application requiring low-power, low-voltage operation and frequent writes. Its single-wire interface and tiny footprint make it an attractive choice for space-constrained applications. Its versatility and functionality make it a great choice for a wide range of applications.
