Microchip Technology's 27HC64 series UVPROM, part number 27HC64-55B-UA, offers 64Kbit (8K x 8) memory organized in an 8-bit width. This CMOS component features a maximum access time of 55ns, with an asynchronous operating mode and 3-state output characteristics. Designed for robust operation across a temperature range of -55°C to +125°C, it is housed in a 32-terminal ceramic chip carrier package (CQCC32). The component supports a nominal supply voltage of 5V and has a programming voltage of 13V. Its common I/O type and parallel interface make it suitable for applications in industrial automation, aerospace, and military systems where reliability and extended temperature performance are critical. Screening conforming to standards such as 38535Q/M, 38534H, and 883B is available.
