Maxim Integrated DS1982-004-740+ECB Product Overview

The DS1982-004-740+ECB from Maxim Integrated is a highly versatile and reliable 1-Wire EEPROM device designed for a multitude of applications requiring a robust and secure method of data storage. This product is part of the iButton® family, which is renowned for its unique form factor and durability, making it suitable for environments where traditional data storage solutions may fail.

With a memory capacity of 1024 bits (128 bytes), the DS1982-004-740+ECB provides users with sufficient storage for small amounts of critical data, such as calibration constants, device identification, and user preferences. The data is organized as four pages of 32 bytes each, and the chip features a write cycle endurance of at least 1,000,000 cycles, ensuring data integrity and longevity.

One of the key features of this device is its 1-Wire interface, which allows for communication and power over a single data line plus ground. This simplifies integration into designs, reduces wiring complexity, and minimizes the overall footprint of the system. The 1-Wire protocol also enables each iButton to have a unique 64-bit serial number, which can be used for secure key access and authentication purposes.

The DS1982-004-740+ECB operates over a wide voltage range from 2.8V to 6.0V and is specified for a temperature range of -40°C to +85°C, making it suitable for harsh industrial environments. Its stainless-steel package not only provides a robust physical container but also offers resistance to environmental hazards such as dust, moisture, and chemicals.

Applications for the DS1982-004-740+ECB are diverse and include asset management, access control, supply chain management, and data logging systems. Its compact size, coupled with its sturdy construction, makes it an ideal choice for portable applications where devices are frequently handled or exposed to potentially damaging conditions.

Maxim Integrated's commitment to quality ensures that the DS1982-004-740+ECB is a reliable and secure choice for designers looking to incorporate a small, yet powerful, data storage solution into their products.
