Microchip Technology introduces the 27HC64-55B-UB, a 64 Kbit UV Erasable Programmable Read-Only Memory. This CMOS device features an 8K x 8 memory organization, providing an access time of 55 ns. Designed for robust operation, it operates across a wide temperature range from -55°C to +125°C. The 27HC64 series UVPROM is housed in a 32-lead Ceramic Quad Flat Package (CQFP), with a terminal pitch of 1.270 mm. Its asynchronous operating mode and 3-state output characteristics make it suitable for various applications. This component finds utility in industrial control systems, data logging, and embedded control applications requiring non-volatile program storage. The 27HC64-55B-UB supports a nominal supply voltage of 5V and is surface mountable.
