Microchip Technology's 27C256-17B-UX is a 32768 x 8 bit CMOS EPROM with a maximum access time of 170ns. This component utilizes a 32-pin Ceramic Quad Flat Pack (CQFP) package, specifically identified by the R-XQCC-N32 code. It operates asynchronously with a nominal supply voltage of 5V and features 3-state outputs. The operating temperature range spans from -55°C to +125°C, with a typical supply current of 20mA. This device is suitable for applications requiring non-volatile program storage, common in industrial control, communication systems, and legacy system upgrades. Its 32K x 8 organization and CMOS technology ensure efficient data retention and low power consumption. The 27C256 series is known for its reliability and adherence to stringent military standards, including 883B screening.
