Microchip Technology AT28LV256-20PI

The AT28LV256-20PI is a high-performance, low-power Electrically Erasable Programmable Read-Only Memory (EEPROM) device from Microchip Technology. This integrated circuit provides a robust storage solution with a 256 Kilobit capacity, making it an ideal choice for applications that require reliable non-volatile memory storage without the need for a battery to maintain the data.

Designed with versatility in mind, the AT28LV256-20PI operates over a wide voltage range of 2.7V to 5.5V, which allows it to be used in a variety of systems with different power requirements. This feature ensures compatibility with both legacy 5V systems and modern low-voltage designs, offering engineers flexibility in integrating the device into their projects.

One of the key features of the AT28LV256-20PI is its fast access time of 200 nanoseconds, enabling quick read operations that are essential for high-speed microprocessor systems. This rapid access time is complemented by the EEPROM's low-power consumption, which is critical for battery-operated and power-sensitive applications.

The AT28LV256-20PI comes in a 28-pin DIP (Dual In-line Package) form factor, which is widely recognized and easy to handle for prototyping and manufacturing processes. Its industry-standard pinout ensures that it can be easily replaced or upgraded without significant changes to the existing PCB layout.

For ease of use, this EEPROM features a simple interface that can be directly connected to the microprocessor's address and data buses. It supports a self-timed write cycle with an automatic erase-before-write capability, which means that no complex programming algorithms are required for data storage operations. Additionally, the device offers hardware data protection features, including a write protect pin to prevent accidental data alteration.

In summary, the Microchip Technology AT28LV256-20PI is a reliable, low-power EEPROM that delivers fast access times and ease of integration, making it an excellent choice for a broad range of applications where data integrity and device longevity are of paramount importance.
