DC ELECTRICAL CHARACTERISTICS
U
Test 1A: For 48-TQFP package only: The 16/68# pin has an internal pull-up resistor, so the input leakage
current is -80uA max.
Test 1B: For 48-TQFP package only: The PwrSave pin has an internal pull-down resistor, so the input leakage
current is 80uA max.
Test 2: The following inputs must remain steady at VCC or GND state to minimize sleep current: A0-A2, D0-D7,
IOR#, IOW# (R/W#), CS# and all modem inputs. Also, RXA and RXB inputs must idle at logic 1 state while
asleep. Floating inputs may result in sleep currents in the mA range. The 48-TQFP package has a higher
current because of the internal pull-up and pull-down resistors on the 16/68# and PwrSave pins respectively.
For Power-Save, the UART internally isolates all of these inputs (except the modem inputs, 16/68# and Reset
pins) therefore eliminating any unnecessary external buffers to keep the inputs steady.
