Maxim Integrated DS2430AP+ 256-Bit 1-Wire EEPROM

The DS2430AP+ is a highly reliable, 256-bit Electrically Erasable Programmable Read-Only Memory (EEPROM) chip from Maxim Integrated, designed for data storage applications that require a small footprint and robust data integrity. This compact memory module utilizes Maxim's exclusive 1-Wire interface, which minimizes the number of wires needed for communication and provides a unique serial number for each device, enabling multiple DS2430AP+ chips to exist on the same 1-Wire bus.

Key Features:

• Memory Size: 256 bits of EEPROM organized as one page of 32 bytes.
• Data Integrity: Each memory page can be permanently write-protected to prevent unintended alterations.
• 1-Wire Interface: Requires only a single data line and a ground return for communication, simplifying system hardware design.
• Unique Serial Number: 64-bit factory-lasered registration number ensures absolute traceability as no two chips are alike.
• Wide Voltage Range: Operates over a wide voltage range of 2.8V to 5.25V, accommodating various system power supplies.
• Low Power Consumption: Designed for power-sensitive applications with a low standby current.
• High Reliability: Offers a data retention period of over 10 years and 50,000 erase/write cycles, ensuring long-term data preservation.

Applications:

The DS2430AP+ is versatile and can be used in a wide array of applications, including:

• Access control systems and secure data storage
• Device authentication and serialization
• Medical and industrial equipment calibration data storage
• Consumer electronics for configuration and preference settings

With its robust design and reliable data storage capabilities, the Maxim Integrated DS2430AP+ EEPROM is an excellent choice for designers looking to implement non-volatile memory storage with minimal interface complexity and a high level of device security.
