The AT27C1024 is a 1-Megabit (64K x 16) Erasable Programmable Read-Only Memory (EPROM) manufactured by Atmel. It is designed for applications requiring non-volatile storage of data or program code, particularly in systems using 16-bit data buses. It is erasable and reprogrammable, offering flexibility in development and updates.

Applications

• Embedded systems for storing program code, especially those utilizing 16-bit processors.
• Firmware storage in electronic devices requiring reprogrammability.
• Data storage in industrial control systems.
• Program storage for microcontrollers.
• Applications requiring non-volatile memory with occasional updates.

Features

• High density: 1-Megabit storage capacity.
• 16-bit wide data path: Optimized for systems using 16-bit processors.
• Erasable: Can be erased using UV light and reprogrammed.
• Fast access time: Enables quick data retrieval. (Specific speed varies by part number suffix).
• Low power consumption: Efficient for embedded applications.
• Single 5V power supply: Simplifies integration.

Benefits

• Suitable for systems needing 16-bit data access.
• Flexibility to update program code or data.
• Reliable storage of non-volatile information.
• Fast execution of code and data retrieval.
• Easy integration into various embedded systems.

Additional Details

The AT27C1024 operates on a single 5V power supply. It is typically available in DIP and PLCC packages. Erasure is achieved through exposure to UV light via a quartz window on the package, after which it can be reprogrammed using an EPROM programmer. The access time depends on the specific part number suffix. Its 'END-OF-LIFE' status indicates it is no longer actively manufactured by Atmel, and availability is contingent on existing stock or surplus vendors. Ensure compatibility with the target system's memory interface requirements.
