The Microchip Technology 27HC641-45I-K is a 64K bit, CMOS UV EPROM organized as 8K words by 8 bits. This component offers a maximum access time of 45ns and operates asynchronously with a 5V supply voltage range of 4.5V to 5.5V. Featuring 3-state outputs, it is housed in a 28-terminal ceramic chip carrier package with a window for erasure, suitable for surface mounting. The 27HC641 series EPROM is utilized in applications requiring non-volatile program storage, including industrial control systems, legacy equipment, and embedded systems where reprogrammability via UV light is advantageous. The operating temperature range is -40°C to +85°C.
