Note: Stresses above those listed under Absolute
Maximum Ratings may cause permanent device failure.
Functionality at or above these limits is not implied. Ex-
posure to absolute maximum ratings for extended peri-
ods may affect device reliability.
OPERATING RANGES
Operating Ranges define those limits between which
the functionality of the device is guaranteed.

Commercial (TC) .................................0°C to +100°C
Industrial* (TA)...................................–40°C to +85°C
VCC up to 33 MHz ..................................... 5 V ± 10%
VCC greater than 33 MHz............................ 5 V ± 5%
Am186EMLV/Am188EMLV Microcontrollers

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 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.
c Power supply current for the Am186EMLV and Am188EMLV microcontrollers, which are available in 20 and 25 MHz
operating frequencies only.
d Testing is performed with the pins floating, either during HOLD or by invoking the ONCE mode.
