The Intel MD2764A/B is a 64K (8K x 8) EPROM (Erasable Programmable Read-Only Memory) chip. This memory device is designed for use in a wide array of applications where non-volatile storage of program code or data is required.

Applications:

• Embedded systems for storing firmware.
• Microcontroller-based systems.
• Industrial control equipment.
• Telecommunications equipment.
• Early personal computers and computer peripherals.

Features:

• Capacity: 64 Kbit (8 K x 8 bits).
• Technology: EPROM (Erasable Programmable Read-Only Memory).
• Access Time: Typically between 200ns and 450ns depending on the specific grade.
• Programming: Can be electrically programmed using a PROM programmer and erased using UV light.
• Package: Typically available in a 28-pin DIP (Dual In-line Package).
• Operating Voltage: +5V single power supply.
• Static Operation: Requires no clock or timing strobes.

Benefits:

• Non-Volatile Storage: Retains data even when power is removed, ensuring reliable storage of critical data or program code.
• Reprogrammable: Can be erased and reprogrammed, allowing for firmware updates and modifications (though requiring UV erasure).
• Wide Operating Temperature Range: Suitable for use in industrial environments with varying temperature conditions.
• Easy Integration: Standard DIP package makes it easy to interface with other components on a circuit board.
• Reliable Performance: Provides dependable data storage and retrieval in demanding applications.

Additional Details:

The MD2764A/B EPROM is erased by exposing the chip to ultraviolet light through a transparent window on the package. The data is then written electrically, typically using a dedicated PROM programmer. The specific access time and power consumption characteristics may vary slightly depending on the manufacturing batch and grade of the device. It's crucial to consult the datasheet for the exact specifications. The device's compatibility is generally with standard TTL logic levels, simplifying interface design.
