This chapter provides the DC and AC electrical charateristics of the ICH3-S.
16.1 Absolute Maximum Ratings
Case Temperature under Bias
Storage Temperature
Voltage on Any 3.3 V Pin with Respect to Ground
Voltage on Any 5 V Tolerant Pin with Respect to Ground (VREF=5V)
1.8 V Supply Voltage with Respect to Vss
3.3 V Supply Voltage with Respect to Vss
5.0 V Supply Voltage (Vref) with Respect to Vss
= 0 °C to +108 °C
= -55 °C to +150 °C
= -0.5 to Vcc + 0.3 V
= -0.5 to VREF + 0.3 V
= -0.5 to +2.7 V
= -0.5 to +4.6 V
= -0.5 to +5.5 V
Warning: Stressing the device beyond the “Absolute Maximum Ratings” may cause permanent damage.
These are stress ratings only. See Section 16.2 for the Functional Operating Range of the ICH3.
Note: A non-condensing environment is required to maintain RTC accuracy.
16.2
Functional Operating Range
All of the AC and DC Characteristics specified in this document assume that the ICH3 component
is operating within the Functional Operating Range given in this section. Operation outside of the
Functional Operating Range is not recommended, and extended exposure outside of the Functional
Operating Range may affect component reliability.
• Case Temperature under Bias = 0 °C to +108 °C
• 1.8 V Supply Voltage (VCC1_8, VccSus1_8) with respect to Vss = 1.71 V to 1.89 V
• 3.3 V Supply Voltage (VCC3_3, VccSus3_3) with respect to Vss = 3.135 V to 3.465 V
• 5 V Supply Voltage (V5REF, V5REF_Sus) with respect to Vss = 4.75 V to 5.25 V
• V_CPU_IO Voltage with respect to Vss =0.950 V to 2.625 V
