Note: Stresses above those listed under Absolute

Maximum Ratings may cause permanent device fail-

ure. Functionality at or above these limits is not implied.

Exposure to absolute maximum ratings for extended

periods may affect device reliability.

OPERATING RANGES

Commercial (TC) .................................0°C to +100°C

Industrial* (TA)...................................–40°C to +85°C

Supply voltage (VCC) .................................5 V ± 10%

Am186EDLV Microcontroller

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 Am186ED microcontrollers are

available in 20 and 25 MHz operating frequencies only.

DC CHARACTERISTICS OVER COMMERCIAL AND INDUSTRIAL OPERATING RANGES

Notes:

The LCS/ONCE0/RAS0 and UCS/ONCE1 pins have weak internal pullup resistors. Loading the LCS/ONCE0/RAS0 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.

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