Note 1: Data in the Typical (“Typ”) column is based on characterization results at 25

°C. This data is for design

guidance only and is not tested.

2: This is the limit to which VDD can be lowered without losing RAM data.

3: When the device is in IR communication (PHACT pin is high), supply current is mainly a function of the

operating voltage and frequency. Pin loading, pin rate and temperature have an impact on the current con-

sumption.The test conditions for all IDD measurements are made when device is:

OSC1 = external square wave, from rail-to-rail; all input pins pulled to VSS, RXIR = VDD, RESET = VDD;

4: When the device is in low power mode (PHACT pin is low), current is measured with all input pins tied to

VDD or VSS and the output pins driving a high or low level into infinite impedance.
