The X2864BP-12 is a 64K (8K x 8) EEPROM (Electrically Erasable Programmable Read-Only Memory) manufactured by Xicor (later acquired by Intersil and then Renesas). It is designed for non-volatile data storage in a variety of applications. The key feature of EEPROMs is their ability to be electrically erased and reprogrammed in-system, providing significant flexibility compared to traditional EPROMs or ROMs.

Applications

• Industrial Control Systems: Stores calibration data, configuration settings, and program code in industrial equipment.
• Data Logging: Used in data loggers to store sensor readings and other data over extended periods.
• Embedded Systems: Provides non-volatile memory for storing program code and configuration data in embedded microcontrollers.
• Instrumentation: Stores calibration constants and program parameters in test and measurement equipment.
• Communication Equipment: Used in modems, routers, and other communication devices for storing configuration information.

Features

• 64K (8K x 8) Memory Organization: Offers a capacity of 64 kilobits arranged as 8192 bytes.
• Electrically Erasable and Programmable: Allows for in-system reprogramming without the need for UV light erasure.
• Fast Access Time (120ns): Provides quick read operations for efficient system performance.
• Self-Timed Write Cycle: Simplifies write operations with an internal timing mechanism.
• Automatic Page Write Operation: Enables efficient writing of multiple bytes in a single operation.
• Low Power Consumption: Minimizes power requirements for energy-sensitive applications.
• JEDEC Standard Pinout: Facilitates easy integration into existing systems.

Benefits

• In-System Reprogrammability: Enables convenient updates and modifications without removing the memory from the system.
• Non-Volatile Storage: Retains data even when power is removed, ensuring data integrity.
• High Endurance: Supports a large number of erase/write cycles.
• Easy Integration: Compatible with standard microcontrollers and memory interfaces.
• Cost-Effective: Provides a cost-efficient solution for non-volatile memory requirements.

Additional Details

The X2864BP-12 typically comes in a DIP (Dual In-line Package) format. The device requires a 5V power supply for operation. The write cycle is self-timed, meaning the user only needs to initiate the write operation, and the device handles the timing internally. Detailed timing diagrams and programming algorithms are available in the manufacturer's datasheet. The "-12" suffix in the part number indicates an access time of 120 nanoseconds.
