NV93C86WF
The NV93C86WF is a serial electrically erasable programmable read-only memory (EEPROM) device manufactured by onsemi, designed for reliable data storage in low-power applications. It offers 512 bits of memory organized into 64 words of 8 bits each, enabling efficient storage of configuration data, calibration values, or user settings in embedded systems. The device supports a wide operating voltage range from 1.7V to 5.5V, making it compatible with various power supply environments across different electronic platforms.
This EEPROM features a simple two-wire interface—comprising a clock (SCL) and data (SDA) line—compatible with the I²C protocol, allowing seamless integration into microcontroller-based designs without requiring complex hardware. It includes built-in write protection mechanisms such as hardware write enable/disable pins and software-based write protection via bit-level locking, enhancing security and preventing accidental overwrites. The NV93C86WF also provides robust endurance of up to 1 million write cycles and data retention for up to 100 years, ensuring long-term reliability in demanding industrial and consumer applications.
The device operates at speeds up to 400 kHz, supporting fast data access while maintaining low power consumption—ideal for battery-powered or energy-sensitive systems. Its compact 8-pin DIP and SO packages offer easy mounting on PCBs, while its wide temperature range from -40°C to +85°C ensures stable performance in harsh environments. Additionally, the NV93C86WF includes self-timed write cycles and internal address auto-increment, simplifying firmware development and reducing host processor overhead during data programming.
Common applications include consumer electronics, automotive systems, industrial controls, and medical devices where non-volatile memory is required for storing calibration parameters, device configurations, or operational logs. It is particularly suited for use in smart sensors, power management ICs, and peripheral modules that demand small footprint, low power, and reliable data retention. With its combination of ease of use, durability, and compatibility, the NV93C86WF serves as a dependable memory solution for modern embedded designs.
