The Microchip Technology 27C64-25-K is a 64 Kbit (8K x 8) CMOS Electrically Programmable Read-Only Memory (EPROM). Featuring an access time of 250ns, this component utilizes a parallel interface for data retrieval. The device operates with a supply voltage range of 4.5V to 5.5V, with a nominal 5V requirement. It is housed in a 32-terminal Ceramic Quad Flat Pack (CQFP) package with a rectangular shape and no leads, conforming to the R-CQCC-N32 standard. The 27C64 series is suitable for applications requiring non-volatile data storage, commonly found in industrial control, consumer electronics, and legacy system upgrades where its robust CMOS technology and asynchronous operation are advantageous. The maximum operating temperature is 70°C.
