The NM93C66LZEMT8 is a 4K-bit MicroWire Serial EEPROM manufactured by National Semiconductor, now part of Texas Instruments (TI). This EEPROM is designed for non-volatile data storage in a variety of electronic devices. It is commonly used to store configuration settings, calibration data, and other critical information that needs to be retained when power is off.

Applications

• Configuration Storage
• Calibration Data Storage
• Parameter Storage
• Identification Data Storage
• Consumer Electronics
• Industrial Control Systems

Features

• 4K-bit EEPROM: Provides 4096 bits of non-volatile memory.
• MicroWire Interface: Uses a simple 3-wire serial interface for easy communication.
• Low Voltage Operation: Operates at low voltages, suitable for battery-powered devices.
• Low Power Consumption: Minimizes power usage in low-power applications.
• High Endurance: Supports a high number of write cycles.
• Data Retention: Retains data for an extended period.

Benefits

• Non-Volatile Storage: Retains data even when power is removed.
• Easy Integration: Simple MicroWire interface simplifies integration with microcontrollers.
• Low Power Operation: Extends battery life in portable devices.
• Reliable Data Storage: High endurance and data retention ensure reliable data storage.
• Compact Size: Small package size allows for use in space-constrained applications.

Additional Details

The NM93C66LZEMT8 typically operates with a supply voltage of 1.8V to 5.5V. It supports a MicroWire serial interface, which requires only three pins for communication (clock, data in, and data out). This EEPROM is designed to have a high number of write cycles (e.g., 1,000,000 cycles) and a long data retention period (e.g., 100 years). It is commonly available in small surface mount packages, such as SOIC or TSSOP. Its low power consumption and ease of use make it a popular choice for storing configuration data and other non-volatile information in a wide range of electronic devices.
