The X2816AP is a 16K (2K x 8) Electrically Erasable PROM (EEPROM) manufactured by Xicor (acquired by Intersil, now Renesas). This EEPROM offers in-system electrical erasure and programming, making it ideal for applications requiring non-volatile memory that can be updated easily. It is commonly used to store configuration data, calibration parameters, and other information that needs to be preserved when power is removed.

Applications

• Configuration storage: Used to store system configuration parameters in embedded systems.
• Calibration data storage: Employed to store calibration coefficients for sensors and other analog components.
• Program memory: Can serve as small-scale program memory for microcontrollers.
• Data logging: Used in data logging applications to store sensor readings and other data.
• Industrial control systems: Integrated into industrial automation equipment to store process parameters and control settings.

Features

• Electrically Erasable: Allows for in-system electrical erasure and programming.
• 16K (2K x 8) organization: Stores 16,384 bits of data organized as 2,048 bytes.
• Page mode write: Enables faster write times by writing multiple bytes simultaneously.
• Self-timed write cycle: Simplifies the write operation by automatically timing the write cycle.
• TTL compatible: Interfaces easily with TTL logic circuits.
• Low power consumption: Reduces power dissipation in battery-powered applications.
• Available in DIP package: Typically available in a standard DIP package.

Benefits

• Easy data updates: Electrical erasure and programming allow for convenient in-system updates.
• Non-volatile storage: Retains data even when power is removed.
• Faster write times: Page mode write improves write performance.
• Simplified write operation: Self-timed write cycle reduces complexity for the user.
• Easy integration: TTL compatibility simplifies interfacing with other logic circuits.
