8 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
