Serial EEPROM
Microchip offers the broadest range of Serial EEPROM devices. Our Serial EEPROMs are low-power, non-volatile memory devices
with wide operating ranges, small-size and byte-alterability, making them ideal for data and program storage. Serial EEPROMs can
be written more than 1 million times and retain data for over 200 years. Innovative low-power designs and extensive testing have
ensured industry-leading endurance and best-in-class quality.

Industry-Leading Testing
Microchip’s best-in-class field performance is the combined
result of world-class manufacturing, wafer-level burn-in and
wafer probe quality screens. Microchip’s Triple-Test Flow is
currently the most robust testing procedure for Serial EEPROM
devices in the industry. It tests each cell of each die three times
and performs extensive endurance and data retention tests
to ensure quality and reliability. Infant mortality of Microchip
Serial EEPROMs is among the lowest in the industry due to
this extensive testing, excellent fabrication and highly-reliable
memory cell design.
Triple-Test Flow
Microchip tests every cell in wafer form twice, then performs a
final test after assembly.
Any die with charge loss in
any cell between the two
probes is rejected to
prevent infant mortality.
