Microchip Technology 24AA256UIDT-I/ST EEPROM
The 24AA256UIDT-I/ST is a high-performance 256Kb I2C™ compatible Serial EEPROM device from Microchip Technology, renowned for its reliability and ease of use in a wide range of applications. This particular EEPROM, encapsulated in a TSSOP-8 package, is designed to provide an efficient non-volatile memory solution with a significant data storage capacity for your sophisticated electronic systems.
One of the key features of the 24AA256UIDT-I/ST is its unique ID which consists of a pre-programmed 128-bit serial number that is unique to each device. This function is particularly useful for applications such as device authentication, inventory management, and network node identification, where a unique identifier is required to ensure the security and integrity of the communication process.
The device operates across a broad voltage range (1.7V to 5.5V), making it suitable for both 5V and 3.3V systems, and ensuring compatibility with most microcontrollers and digital systems without the need for level shifters. It is designed to work reliably in extreme temperature environments, with an operational temperature range from -40°C to +85°C, which qualifies it for industrial-grade applications.
Communication with the 24AA256UIDT-I/ST is achieved via the I2C serial interface, which supports standard (100 kHz), fast (400 kHz), and high-speed (1 MHz) modes, offering flexibility in system design and ensuring fast data transfer rates. Additionally, the EEPROM supports byte-level and page-level write operations, which can greatly optimize write performance and minimize write cycle time.
With its built-in write protect feature, it allows the user to prevent accidental writes to the memory, thus safeguarding the stored data. Moreover, the EEPROM provides a long data retention period and supports a high endurance of one million write cycles per byte, ensuring the reliability and longevity of the device.
In summary, the Microchip 24AA256UIDT-I/ST is an excellent choice for designers looking for a robust, high-capacity, and unique-identifier-equipped EEPROM for their data storage needs. Whether it's for complex industrial systems, consumer electronics, or secure authentication tasks, this EEPROM stands out with its performance and durability.
