Microchip Technology AT24C256BNSU18

The AT24C256BNSU18 is a high-performance 256Kb I2C-compatible EEPROM (Electrically Erasable Programmable Read-Only Memory) device from the renowned manufacturer, Microchip Technology. This memory module is designed for optimal storage solutions where low-power and low-voltage operations are essential. It is particularly suitable for a wide range of applications, including industrial, automotive, and consumer electronics where reliable and durable non-volatile memory storage is required.

Featuring a 256-kbit (32,768 x 8) memory size, the AT24C256BNSU18 provides ample space for critical data storage such as device configuration settings, calibration data, or small application programs. The EEPROM operates over a voltage range of 1.8V to 5.5V, which allows for flexible integration into various system designs without the need for level shifters or voltage regulators.

The device supports the standard I2C serial interface, facilitating easy connection to microcontrollers and other digital systems with a bus speed of up to 1 MHz. This makes it an excellent choice for systems that require fast data transfer rates and seamless communication with other I2C-compatible devices. The AT24C256BNSU18 also offers a write protect pin to prevent inadvertent writes, thereby ensuring the integrity of the stored data.

One of the key features of the AT24C256BNSU18 is its low-power consumption, which is critical for battery-operated devices. It has a very low active read current and an even lower standby current, making it an energy-efficient choice for portable applications. The device also boasts a high endurance with a write cycle rating of 1 million write cycles per byte and a data retention period of over 100 years, ensuring the longevity and reliability of the stored information.

The AT24C256BNSU18 comes in an 8-lead SOIC package, which is known for its compact footprint and ease of integration into PCB designs. The small form factor combined with its robust performance characteristics makes the AT24C256BNSU18 a versatile and reliable EEPROM solution for designers looking to enhance their system's memory capabilities.
