The MD2764A-20/B is a 64K (8K x 8) EPROM (Erasable Programmable Read-Only Memory) manufactured by Intel. This memory chip is designed for storing firmware, boot code, and other non-volatile data in electronic systems. The '20' in the part number indicates an access time of 200ns.

Applications:

• Embedded Systems: Stores firmware and boot code for microcontrollers and embedded processors.
• Industrial Control Systems: Used in programmable logic controllers (PLCs) and other industrial automation equipment.
• Consumer Electronics: Employed in older video game consoles, printers, and other electronic devices requiring non-volatile memory.
• Instrumentation: Stores calibration data and program code in test and measurement equipment.
• Telecommunications Equipment: Used in network devices for storing configuration data.

Features:

• 64K Bit Capacity: Provides 65,536 bits (8,192 bytes) of non-volatile storage.
• EPROM Technology: Erasable and reprogrammable using ultraviolet (UV) light.
• 200ns Access Time: Offers relatively fast read access to stored data.
• Single 5V Power Supply: Operates on a single 5-volt power supply.
• Three-State Outputs: Allows for easy bus interfacing.
• JEDEC Standard Pinout: Conforms to industry-standard pinout configurations.
