Features, Applications

The 32k UV erasable and electrically reprogrammable CMOS EPROM ideally suited for applications where fast turnaround pattern experimentation and low power consumption are important requirements The NMC27C32B is designed to operate with a single a 5V power supply with g 10% tolerance The NMC27C32B is packaged a 24-pin dual-in-line package with a quartz window The quartz window allows the user to expose the chip to ultraviolet light to erase the bit pattern A new pattern can then be written electrically into the device by following the programming procedure This EPROM is fabricated with National's proprietary time proven CMOS double-poly silicon gate technology which combines high performance and high density with low power consumption and excellent reliability


Low CMOS power consumption Active Power 55 mW Max Standby Power 55 mW Max Extended temperature range 85 C Fast and reliable programming TTL CMOS compatible inputs outputs TRI-STATE output Manufacturer's identification code for automatic programming High current CMOS level output drivers Compatible with NMOS 2732
