The Microchip Technology AT28C64X-25TI is a high-performance 64Kbit CMOS Electrically Erasable Programmable Read-Only Memory (EEPROM). This parallel interface device features an 8K x 8 memory organization, providing 8192 words of data storage. With a maximum access time of 250ns and a write cycle time of 200µs, it is suitable for applications demanding rapid data retrieval and modification. The AT28C64X-25TI operates across a wide temperature range of -40°C to +85°C and supports a supply voltage from 4.5V to 5.5V. Its 28-lead package (PDSO28) is designed for surface mounting with a 0.55mm terminal pitch. Key features include data polling for read/write status, asynchronous operation, and 3-state outputs. This EEPROM finds application in industrial control, medical equipment, and consumer electronics requiring reliable non-volatile data storage. It offers 100,000 endurance cycles and 10 years of data retention.
