In order to provide adequate filtering and in-rush current
protection for any system design, bulk capacitance is
required. A small amount of bulk capacitance is supplied on
VR_ON Valid-Low Time: This specifies how long VR_ON needs to be low for a valid off before VR_ON can be
turned back on again. In going from a valid on to off and then back on, the following conditions must be met to
prevent damage to the OEM system or the Intel mobile module:
VR_PWRGD
1. PWROK on I/O board should be active on when VR_PWRGD is active and V_3S is good.
2. CPU_RST from I/O board should be active for a minimum of 6 ms after PWROK is active and PLL_STP# and CPU_STP# are
3. V_DC >= 4.7V, V_5>=4.5V, V_3S>=3.0V.
4. V_CPUPU and V_CLK are generated on the Intel Mobile Module.
5. This is the 5V power supplied to the processor module connector. This should be the first 5V plane to power up.
6. VR_PWRGD is specified to its associated high/active by the module regulator within less than or equal to 6 ms max. after the
V_CPUPU/
VR_ON must be low for 1 millisecond.
The original voltage level requirements for turn-on must be met before assertion of VR_ON (i.e. V_DC
