Voltage on any pin with respect to ground

Am186/188EM ........................... –0.5 V to Vcc +0.5 V

Am186/188EMLV ....................... –0.5 V to Vcc +0.5 V

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.

Am186EM/Am188EM Microcontrollers

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

Commercial (TA) ................................... 0°C to +70°C

VCC up to 25 MHz ................................. 3.3 V ± 0.3 V

Where:

TC = case temperature

TA = ambient temperature

*Industrial versions of Am186EM and Am188EM microcontrol-

lers are available in 20 and 25 MHz operating frequencies

only.

DC CHARACTERISTICS OVER COMMERCIAL OPERATING RANGE

Notes:

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.

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.

Power supply current for the Am186EMLV and Am188EMLV microcontrollers, which are available in 20 and 25 MHz

operating frequencies only.

Testing is performed with the pins floating, either during HOLD or by invoking the ONCE mode.
