The MD2764-25/B is an EPROM (Erasable Programmable Read-Only Memory) manufactured by Intel. It's a type of non-volatile memory that can be electrically programmed and erased, although the erasure process typically involves exposure to ultraviolet light. This particular model is characterized by its storage capacity and access time.

Applications

• Embedded Systems: Used for storing firmware or boot code in embedded systems.
• Industrial Control Systems: Employed in programmable logic controllers (PLCs) and other industrial control equipment to store control algorithms and configuration data.
• Instrumentation: Used in test and measurement equipment to store calibration data and instrument settings.
• BIOS Storage: Historically used in personal computers to store the Basic Input/Output System (BIOS) code.
• Arcade Games: Used in older arcade game systems to store game ROMs.

Features

• EPROM Technology: Electrically programmable and erasable (UV erasure).
• Non-Volatile Memory: Retains data even when power is removed.
• 250ns Access Time: Offers a relatively fast access time of 250 nanoseconds.
• Industry Standard Pinout: Compatible with standard EPROM pin configurations.
• Single 5V Power Supply: Operates with a single 5-volt power supply.

Benefits

• Firmware Storage: Provides a reliable and cost-effective solution for storing firmware in various applications.
• Program Updates: Allows for program updates and modifications through UV erasure and reprogramming.
• Data Retention: Ensures data retention even during power outages or system failures.
• System Integration: Facilitates easy integration into existing systems due to its industry-standard pinout.
• Cost-Effective Solution: Offers a relatively low-cost solution for non-volatile memory requirements.

Specifications

The MD2764-25/B typically has a storage capacity of 64 kilobits (8 kilobytes). It operates on a single 5V power supply and features a typical access time of 250 nanoseconds. The device requires a UV eraser for erasing the stored data before reprogramming. Consult the official Intel datasheet for detailed electrical characteristics, timing diagrams, and pinout information.
