The AT27BV400-15JC is a 4-megabit (512K x 8) One-Time Programmable Read-Only Memory (OTP EPROM) manufactured by Atmel. It is designed for applications requiring non-volatile storage of data or code. The '-15JC' likely indicates the speed grade (150ns access time) and package type (J-leaded Ceramic).

Applications

• Embedded systems for storing program code.
• Firmware storage in electronic devices.
• Data storage in industrial control systems.
• Look-up tables in signal processing applications.
• Boot ROMs in computer systems.

Features

• Fast access time: 150 ns access time for quick data retrieval.
• Low power consumption: Minimizes power requirements in embedded systems.
• Single 5V power supply: Simplifies system design.
• JEDEC standard pinout: Facilitates easy integration with existing systems.
• One-time programmable: Suitable for applications where code or data rarely changes.

Benefits

• Reliable storage of program code and data.
• Fast execution of code from memory.
• Easy integration into embedded systems.
• Cost-effective solution for non-volatile storage.
• Suitable for applications with stable firmware or data.

Additional Details

The AT27BV400-15JC operates from a single 5V power supply. It is available in a J-leaded ceramic package (JC). The EPROM utilizes a standard JEDEC pinout for easy system integration. As an OTP device, it can be programmed only once, making it suitable for applications where the stored data or code is relatively static. It is categorized as 'END-OF-LIFE', indicating that it is no longer actively manufactured by Atmel, so availability may be limited to existing stock or surplus markets. Programming requires a dedicated EPROM programmer.
