The X28C64DI-20 is a 64K EEPROM (Electrically Erasable Programmable Read-Only Memory) manufactured by Xicor Inc. This memory device is non-volatile, meaning it retains its data even when power is removed. The '-20' likely indicates an access time of 200ns.

Applications

• Storing configuration data in embedded systems.
• Storing calibration data in instruments.
• Storing firmware in microcontrollers.
• Replacing DIP switches and potentiometers.
• Storing user preferences in electronic devices.

Features

• 64K (8K x 8) memory capacity.
• Non-volatile data storage.
• Electrically erasable and programmable.
• Fast access time (200ns).
• Low power consumption.
