Typical Characteristics
AT89LP51RD2/ED2/ID2 Preliminary
Supply Current (Internal Oscillator)
The following charts show typical behavior. These figures are not tested during manufacturing.
All current consumption measurements are performed with all I/O pins configured as quasi-bidi-
rectional (with internal pull-ups). A square wave generator with rail-to-rail output is used as an
external clock source for consumption versus frequency measurements.
