Notes:
a
The LCS/ONCE0, MCS3–MCS0, UCS/ONCE1, and RD pins have weak internal pullup resistors. Loading the LCS/ONCE0
and UCS/ONCE1 pins in excess of IOH = –200 µA during reset can cause the device to go into ONCE mode.
b
c
d
Current is measured with the device in RESET with X1 and X2 driven and all other non-power pins open but held High or Low.
Testing is performed with the pins floating, either during HOLD or by invoking the ONCE mode.
Power supply current for the Am186ESLV and Am188ESLV microcontrollers, which are available in 20 and 25 MHz operating
frequencies only.
