FM1608B

Recent testing has uncovered a problem with the FM1608B at cold temperatures.

These parts meet the current datasheet specifications with the following exceptions:

1. All datasheet parameters are as specified provided the operating temperature is ≥ -15°C.

2. If -25°C minimum operating temperature is required, then you must comply with a minimum

VDD Fall Time (tVF) of 200µs/V.

There is a design change in process to improve the cold temperature performance. An update will be

issued when the design change has been verified.

UPDATE: Ramtron has implemented a cold test (-40C) such that all devices comply with the datasheet

specifications without exception over the full industrial temperature range -40C to +85C. Therefore the

above errata no longer applies. The starting date code for errata-free devices is 1148. (YY=11, WW=48)
