Microchip Technology AT28HC256E-12TU EEPROM

The AT28HC256E-12TU is a high-performance Electrically Erasable Programmable Read-Only Memory (EEPROM) integrated circuit produced by Microchip Technology. Designed with convenience and reliability in mind, this EEPROM offers a robust storage solution for a wide range of applications. The device's 256K (32,768 x 8) memory array allows users to store substantial amounts of data with ease.

This particular model, with its 120 ns access time, is tailored for applications that require fast data retrieval, making it an excellent choice for performance-critical systems. The AT28HC256E-12TU is packaged in a 28-lead TSOP (Thin Small Outline Package), which is ideal for space-constrained applications while also providing excellent reliability and environmental endurance.

One of the key features of the AT28HC256E-12TU is its hardware data protection, which includes a write protect pin to prevent inadvertent write or erase cycles. This ensures that your data remains safe even in the event of unexpected conditions such as power fluctuations. Additionally, the EEPROM supports a full 5V ±10% operating range, making it compatible with a wide variety of microcontrollers and digital systems.

With its low-power consumption, the AT28HC256E-12TU is an energy-efficient choice for battery-operated devices. The EEPROM enters into standby mode when not in use, further reducing power consumption and extending battery life in portable applications.

Programming the AT28HC256E-12TU is straightforward, thanks to its self-timed write cycle feature. This means that no external timers are required for write operations, simplifying the design and reducing the overall component count. The device also features page write operation, allowing up to 64 bytes to be written in one write cycle, enhancing the efficiency of data logging or batch processing tasks.

In summary, the AT28HC256E-12TU from Microchip Technology is a versatile, high-speed EEPROM that delivers reliable data storage with features designed to safeguard your data and simplify integration into your projects. Its combination of speed, density, and robustness makes it an ideal memory solution for a multitude of electronic applications.
