The QD2764A is a 64K (8K x 8) EPROM (Erasable Programmable Read-Only Memory) manufactured by Intel. It is a non-volatile memory device that can be electrically programmed and erased using ultraviolet light. This EPROM is used to store firmware, boot code, and other essential data in various electronic systems.

Applications

• Embedded systems
• Microcontroller firmware storage
• Boot ROM for computers
• Industrial control systems
• Instrumentation

Features

• 64K (8K x 8) memory organization
• Erasable and reprogrammable using UV light
• Fast access time (typically around 250-450ns, depending on the specific grade)
• TTL compatible inputs and outputs
• Single 5V power supply operation
• Three-state output

Benefits

• Non-volatile storage: Retains data even when power is removed.
• Reprogrammable: Allows for updates and modifications to the stored data.
• Fast access time: Enables quick retrieval of stored information.
• Easy integration: TTL compatible inputs and outputs simplify interfacing with other digital components.
• Wide operating temperature range: Suitable for use in various environmental conditions.

Technical Specifications

The QD2764A operates from a single 5V power supply. It features address inputs, data outputs, chip enable, and output enable control signals. The device's access time varies depending on the specific grade. The operating temperature range is usually 0°C to 70°C. The package is typically a ceramic DIP package with a quartz window for UV erasure. Detailed timing diagrams and electrical characteristics are available in the product datasheet.
