FM25V01

The FM25V01 devices have a problem with the sleep mode function. Some devices will not exit sleep at

Vdd voltages within the specified operating range. Worst case is at high VDD (3.6V). The failing voltage

will be lower at cold temperatures. This does not affect operation if the sleep function is not used.

There is an effective screen that is implemented at final test. A temporary part number has been assigned

for customers who use sleep mode. Customers who require sleep mode should order the FM25V01-G.

The part will be marked with a triangle to the right of the part mark. An example of the mark is as

follows:

XXXXXXX-PT

RLLLLLLLL

No Sleep Mode Screen

This errata will remain in effect until the sleep function is fixed.

UPDATE: Ramtron has made circuit modifications to correct this problem. The starting date code for the

fixed devices is 1127. (YY=11, WW=27) Devices with a date code 1127 and later have a fully operational

sleep mode function.

An example of the new part marking is as follows:
