Microchip Technology 27HC64-45I-K is a 64 Kbit (8K x 8) CMOS UV Erasable Programmable Read-Only Memory (UVPROM) featuring an asynchronous operating mode. This component offers a maximum access time of 45ns and operates from a 5V supply voltage range of 4.5V to 5.5V. The 27HC64 series utilizes CMOS technology for efficient power consumption, with a typical standby current of 50mA. Packaged in a 32-terminal Ceramic Quad Flat Pack (CQFP) with a window for UV erasure, this device is suitable for surface mounting. Its parallel interface and 3-state output characteristics make it a robust solution for data storage and program execution in applications such as industrial control systems, telecommunications infrastructure, and legacy system upgrades. The component is rated for an industrial operating temperature range of -40°C to +85°C.
