Table 3. Static Electrical Characteristics
TA = -40 to 85 °C, VPWR = 3.0 to 4.4 V, in gathering these parametrics, Freescale used the external components described in
the Hardware Design Considerations section of this document, over the full load current range, unless otherwise noted. Typical
values are characterized at VPWR = 3.6 V and 25 °C.
