Electrical Parameters

Except as noted, conditions for the following specifications are Tamb = -25°C to +85°C (25°C typical); VCC = 2.7V to 5.5V.

Production testing of the chip is performed at 25°C; VCC=3.6V, unless otherwise stated. Functional operation of the chip and

specified parameters at other temperatures are guaranteed by design, characterization, and process control.
