ABSOLUTE MAXIMUM RATINGS
Temperature under bias:
OPERATING RANGES
TC (Commercial) ............................ 0°C to +100°C
Industrial* (TA) ..............................–40°C to + 85°C
VCC up to 50 MHz ............................. 3.3 V ± 0.3 V
Commercial (TC) ........................0°C to + 100°C
Storage temperature ..................–65°C to + 125°C
Voltage on any pin with
respect to ground.......................... –0.5 V to VCC + 2.6 V*
Where: TC = case temperature
TA = ambient temperature
Notes:
Notes:
Stresses above those listed under Absolute Maximum Rat-
ings may cause permanent device failure. Functionality at or
above these limits is not implied. Exposure to absolute maxi-
mum ratings for extended periods may affect device reliability.
Operating Ranges define those limits between which the
functionality of the device is guaranteed.
*Industrial versions of Am186ER and Am188ER microcon-
trollers are available in 25- and 33-MHz operating frequen-
cies only.
*X1 and X2 are not 5-V-tolerant and have a range of –0.5 V to
VCC

Notes:
1. This parameter is for inputs without pullup or pulldown resistors and for which 0 ≤ VIN ≤ VCC
.
2. This parameter is for inputs without pullup or pulldown resistors and for which 0 ≤ VIN ≤ 5 V.
3. This parameter is for inputs with pulldown resistors and for which VIH = 2.4 V.
4. This parameter is for inputs with pullup resistors and for which VIL = 0.45 V.
5. This parameter is for three-state outputs where VEXT is driven on the three-state output and 0 ≤ VEXT ≤ VCC
.
6. This parameter is for three-state outputs where VEXT is driven on the three-state output and 0 ≤ VEXT ≤ 5 V.
7. This parameter has not been fully tested.
8. 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.
