Microchip Technology's 27C256-25B-XA is a 32768 x 8 bit CMOS EPROM. This asynchronous memory device offers a maximum access time of 250ns, facilitating rapid data retrieval. Operating from a nominal 5V supply, it features 3-state outputs and common I/O for flexible system integration. The component utilizes through-hole mounting with a 2.54mm terminal pitch, housed in a 28-pin CDIP package (JESD-30 Code R-XDIP-T28). Its robust design supports an extended operating temperature range from -55°C to +125°C, meeting MIL-STD-883B screening standards. This high-reliability EPROM finds application in industrial control, aerospace, and defense systems requiring non-volatile program storage. Standby current is rated at a maximum of 0.1mA, with a maximum active supply current of 65mA.
