The Microchip Technology AT28C256E-15LM is a 262,144-bit (32K x 8) parallel Electrically Erasable Programmable Read-Only Memory (EEPROM) device. Operating with a 150ns access time, this CMOS component offers robust data retention and a minimum of 100,000 endurance cycles. It supports asynchronous operation and features automatic write capabilities, including data polling for status monitoring. The AT28C256E-15LM is designed for a wide industrial temperature range of -55°C to +125°C and operates from a 4.5V to 5.5V supply. Its 32-terminal CQCC32 package, featuring no leads with a 1.27mm terminal pitch, makes it suitable for surface-mount applications. This memory solution finds utility in industrial control, automotive systems, and data logging applications where reliable non-volatile storage is critical.
