The AM2764A-45/BXA is a 64K (8192 x 8) electrically programmable read-only memory (EPROM) from AMD. Similar to the AM2764, it offers non-volatile data storage, retaining information even without power. The 'A' designation often indicates an improved version, potentially with faster access times or lower power consumption compared to the base model. However, this particular variant maintains a 450ns access time.

Applications

• Embedded Systems Firmware Storage: Used for storing firmware in microcontrollers and embedded systems.
• Boot Loaders: Implements boot loaders in computer systems and electronic devices.
• Data Tables: Stores calibration data and look-up tables for various applications.
• Game Cartridges: Used in older video game consoles to store game data.
• Industrial Automation: Stores control programs and configuration data in industrial equipment.

Features

• 64K (8192 x 8) Memory Organization: Provides 65,536 bits of storage organized as 8192 bytes.
• Single +5V Power Supply Operation: Operates on a single 5V power supply, simplifying system design.
• 450ns Access Time: Enables relatively fast data retrieval for various applications.
• Static Operation: Requires no clock signals or refresh cycles for data retention.
• Three-State Outputs: Offers three-state output drivers for flexible bus interfacing.
• Electrically Programmable: Can be programmed and reprogrammed using an EPROM programmer.

Benefits

• Non-Volatile Data Storage: Ensures data retention even when power is removed.
• Simple Integration: Easy to interface with microprocessors and other digital circuits.
• Cost-Effective Solution: Provides a reasonably priced solution for storing program code and data.
• High Reliability: AMD's manufacturing ensures reliable operation over a wide temperature range.
• Wide Range of Applications: Suitable for various applications requiring non-volatile memory.

Additional Details

The AM2764A-45/BXA is typically packaged in a 28-pin DIP package. Programming is typically done using a dedicated EPROM programmer. The device is erased by exposing it to ultraviolet light through a quartz window located on the top of the package. Pay close attention to the device's programming specifications to avoid damage during programming.
