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: The supply current is mainly a function of the operating voltage and frequency. Pin loading, pin rate, and
temperature have an impact on the current consumption.
a) The test conditions for all IDD measurements are made when device is enabled (EN pin is high):
OSC1 = external square wave, from rail-to-rail; all input pins pulled to VSS, RXIR = VDD,
RESET =VDD;
b) When device is disabled (EN pin is low), the conditions for current measurements are the same.
4: When the device is disabled (EN 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.
