The Microchip Technology 27HC641-45B-UB is an 8K x 8 (64 Kbit) UV Erasable Programmable Read-Only Memory (UVPROM) device. This CMOS component offers a fast 45ns access time, facilitating high-speed data retrieval. Its asynchronous operating mode and 3-state output characteristics ensure efficient system integration. Designed for robust performance across a wide temperature range of -55°C to +125°C, it is housed in a 28-terminal Ceramic Quad Flat Pack (CQFP) package. The 27HC641 series finds application in industrial control, aerospace, and defense systems where reliable, non-volatile program storage is critical. This UVPROM meets stringent military screening standards, including 883B.
