Microchip Technology's 28C64A-25B-UA is a 64-kilobit CMOS Electrically Erasable Programmable Read-Only Memory (EEPROM) organized as 8K words by 8 bits. This parallel interface device offers a maximum access time of 250 nanoseconds and operates from a nominal 5V supply. It features data polling and ready/busy status indication for efficient system integration. The 28C64 series is designed for high-reliability applications, supporting a wide operating temperature range from -55°C to +125°C. Encased in a 32-terminal Ceramic Quad Flat Pack (CQFP) package with a no-lead terminal form, it is suitable for surface-mount assembly. This component finds application in industrial control, medical devices, and telecommunications equipment requiring non-volatile data storage. Its robust construction aligns with MIL-STD-883B and other stringent screening standards.
