60 / 112 page 60 Am186TMER and Am188TMER Microcontrollers Data Sheet DRAF T ABSOLUTE MAXIMUM RATINGS Temperature under bias: 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 * 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. *X1 and X2 are not 5-V-tolerant and have a range of –0.5 V to VCC. 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 Where: TC = case temperature TA = ambient temperature Notes: 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. DC CHARACTERISTICS OVER COMMERCIAL AND INDUSTRIAL OPERATING RANGES Notes: 1. This parameter is for inputs without pullup or pulldown resistors and for which 0 ≤ V IN ≤ VCC. 2. This parameter is for inputs without pullup or pulldown resistors and for which 0 ≤ V IN ≤ 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.
