The AM2864A-25/BXA is a 64K (8K x 8) EEPROM (Electrically Erasable Programmable Read-Only Memory) manufactured by AMD. This device offers non-volatile storage with in-system programmability and erasability, making it suitable for applications requiring frequent data updates and flexible memory management. It provides a cost-effective solution for storing configuration data, calibration parameters, and user preferences in a variety of embedded systems.

Applications:

• Storage of configuration data in embedded systems
• Calibration parameter storage
• Storage of user preferences
• Data logging
• Firmware updates

Features:

• 64K (8K x 8) memory organization
• Electrically erasable and programmable
• Fast access time (250ns)
• Single +5V power supply
• TTL compatible inputs and outputs
• In-system programmability
• Page write mode for faster programming

Benefits:

• Non-volatile storage ensures data retention without power.
• In-system programmability allows for easy data updates without removing the device from the circuit.
• Fast access time enables quick data retrieval.
• Low power consumption makes it suitable for battery-powered applications.
• TTL compatibility simplifies integration with existing logic circuits.

Additional Details:

The AM2864A-25/BXA is typically packaged in a 28-pin DIP (Dual In-line Package). The device can be electrically erased and reprogrammed multiple times, providing flexibility in memory management. The page write mode allows for faster programming by writing multiple bytes simultaneously. The operating temperature range is typically from 0°C to +70°C. The EEPROM is designed to withstand a certain number of erase/program cycles, ensuring reliability over its lifespan. The write enable (WE) and output enable (OE) pins provide control over the write and read operations, respectively.
