Overview

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.

Re-calculate Data

Data is based on the following assumptions.

Note: The temperature and confidence level may be adjusted to your requirements.

Disclaimer: A reliability FIT rate calculated using this tool shall not be used for any functional safety purpose. In case a raw FIT rate needs to be estimated for a component which is targeted to be used in a safety critical application (i.e. compliant to ISO 26262 standard) it should be calculated according to generic safety standards (IEC62380, IEC61709, SN29500, FIDES, etc.)
