Industrial and Medical
MEMS RTCs Meet Critical Factors for Industrial and Medical Applications in
Ruggedness, Size, and Temperature
Industrial and medical markets have expanded their acceptance of MEMS-
accurate RTCs based on the newly introduced 8-pin, 150-mil SO package,
the inherent ruggedness of the MEMS design, and the status and success
of the standard device’s AEC-Q100 automotive qualification. Long-term
accuracy (< ±5ppm) of the MEMS RTC contributes to its acceptance
in these applications, where demand for highly reliable and accurate
timekeeping/time-stamping of event data is extremely critical.
Temperature performance is extremely important for industrial
applications. The standard device provides a wide (-40°C to +85°C)
operating temperature range by keeping accurate time across this band
of temperatures. Low operating currents (< 3.5μA) and the 2.3V to 5.5V
wide-operating voltage range aid critical portable medical applications
that are battery powered. Heavy machinery, blood glucose meters, and
environmental system controls benefit from the high accuracy, low power
consumption, device ruggedness, and small package size.
