Applications The MAX16067 features nonvolatile fault memory for Networking Equipment recording information during system shutdown events. Telecom Equipment (Base Stations, Access) The fault logger records a failure in the internal flash and sets a lock bit protecting the stored fault data from Storage/RAID Systems accidental erasure. Servers An SMBus or a JTAG serial interface configures the MAX16067. The MAX16067 is available in a 32-pin, 5mm Typical Operating Circuit appears at end of data sheet. x 5mm, TQFN package and is fully specified over the -40NC to +85NC extended temperature range.

Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability. ELECTRICAL CHARACTERISTICS (V = 2.8V to 14V, T = T = -40NC to +85NC, unless otherwise specified.
