EEPROM Memory | N21C21A
概览
The N21C21A is a 1K−bit serial EPROM containing a factory−programmed, unique 48−bit identification number, 8−bit CRCgeneration, and the 8−bit family code (09h). A 64−bit status register controls write protection and page redirection.The N21C21A 1−wire interface requires only a single connection and a ground return. The DATA pin is also the sole power source for the N21C21A.The small surface−mount package options saves printed−circuit−board space, while the low cost makes it ideal for applications such as battery pack configuration parameters, record maintenance, asset tracking, product−revision status, and access−code security.
