Industrial temperature devices

Due to ever increasing requirements for portability and operation under extreme

environmental conditions, STMicroelectronics offers industrial temperature versions

(–40°C to +85°C) of our serial RTC devices. This expanded operating range allows these

products to perform under more extreme temperatures for applications such as:

●

cell phone base stations;

●

traffic control;

●

portable equipment;

●

land, water, and aircraft instrumentation; and

●

industrial control equipment.

These products are indicated by the digit ‘6’ at the end of the sales-type. The industrial

data retention lifetimes are listed in Appendix B: ZEROPOWER products on page 26 and

Appendix C: TIMEKEEPER® products on page 28.
