The AM2764-45/BXA is a 64K (8192 x 8) electrically programmable read-only memory (EPROM) manufactured by AMD. It's a non-volatile memory device, meaning it retains its data even when power is removed. This particular variant has an access time of 450ns.

Applications

• Microcontroller Programs Storage: Used to store firmware and program code in embedded systems.
• Boot ROMs: Functions as a boot ROM in various computer systems and peripherals.
• Character Generators: Stores character fonts for displays and printers.
• Lookup Tables: Implements lookup tables for signal processing or control applications.
• Industrial Control Systems: Stores configuration data and control algorithms in industrial equipment.

Features

• 64K (8192 x 8) Organization: Stores 65,536 bits of data arranged as 8192 bytes.
• Single +5V Power Supply: Operates from a single 5V power supply for ease of integration.
• Fast Access Time (450ns): Allows for quick retrieval of stored data.
• Static Operation: Requires no clocks or refreshing for simple operation.
• Three-State Output: Provides three-state outputs for easy bus interfacing.
• Programmable: Can be electrically programmed by the user.

Benefits

• Non-Volatile Storage: Retains data even when power is off, ensuring reliable storage.
• Easy to Use: Simple interface and operation simplifies system integration.

Additional Details

The AM2764-45/BXA is typically packaged in a 28-pin DIP (Dual In-line Package). Programming typically involves using a dedicated EPROM programmer to apply specific voltage levels to the device's pins. Erasing is accomplished by exposing the device to ultraviolet light through a quartz window on the top of the package.
