SHDN When asserted (logic low), this input instructs the power switch to turn off all voltage outputs and the discharge FETs are activated. SHDN has an internal pullup connected to AUXIN. STBY When asserted (logic low) after the card is inserted, this input places the power switch in standby mode by turning off the 3.3-V and 1.5-V power switches and keeping the AUX switch on. If asserted prior to the card being present, STBY places the power switch in OFF Mode by turning off the AUX, 3.3-V, and 1.5-V power switches. STBY has an internal pullup connected to AUXIN. RCLKEN This pin serves as both an input and an output. On power up, a discharge FET keeps this signal at a low state as long as any of the output power rails are out of their tolerance range. Once all output power rails are within tolerance, the switch releases RCLKEN allowing it to transition to a high state (internally pulled up to AUXIN). The transition of RCLKEN from a low to a high state starts an internal timer for the purpose of deasserting PERST. As an input, RCLKEN can be kept low to delay the start of the PERST internal timer. Because RCLKEN is internally connected to a discharge FET, this pin can only be driven low and should never be driven high as a logic input. When an external circuit drives this pin low, RCLKEN becomes an input; otherwise, this pin is an output. RCLKEN can be used by the host system to enable a clock driver. PERST On power up, this output remains asserted (logic level low) until all power rails are within tolerance. Once all power rails are within tolerance and RCLKEN has been released (logic high), PERST is deasserted (logic high) after a time delay as shown in the parametric table. On power down, this output is asserted whenever any of the power rails drop below their voltage tolerance. The PERST signal is an output from the host system and an input to the ExpressCard module. This signal is only used by PCI Express-based modules and its function is to place the ExpressCard module in a reset state. During power up, power down, or whenever power to the ExpressCard module is not stable or not within voltage tolerance limits, the ExpressCard standard requires that PERST be asserted. As a result, this signal also serves as a power-good indicator to the ExpressCard module, and the relationship between the power rails and PERST are explicitly defined in the ExpressCard standard. The host can also place the ExpressCard module in a reset state by asserting a system reset SYSRST. This system reset generates a PERST to the ExpressCard module without disrupting the voltage rails. This is what is normally called a warm reset. However, in a cold start situation, the system reset can also be used to extend the length of time that PERST is asserted.

Asserting SYSRST (logic low) forces PERST to assert. RCLKEN is not affected by the assertion of SYSRST. SYSRST has an internal pullup connected to AUXIN. OC This pin is an open-drain output. When any of the three power switches (AUX, 3.3V, and 1.5V) is in an overcurrent condition, OC is asserted (logic low) by an internal discharge FET with a deglitch delay. Otherwise, the discharge FET is open, and the pin can be pulled up to a power supply through an external resistor.

If AUXIN is present and SHDN is asserted (logic low), then all input-to-output power switches are kept off and the output discharge FETs are turned on (Shutdown mode). If SHDN is asserted and then de-asserted, the state on the outputs is restored to the state prior to SHDN assertion. If 3.3VIN, AUXIN and 1.5VIN are present at the input of the power switch and no card is inserted, then all input-to-output power switches are kept off and the output discharge FETs are turned on (No Card mode). If 3.3VIN, AUXIN and 1.5VIN are present at the input of the power switch prior to a card being inserted, then all input-to-output power switches are turned on once a card-present signal (CPUSB and/or CPPE) is detected (Card Inserted mode). If a card is present and all output voltages are being applied, then the STBY is asserted (logic low); the AUXOUT voltage is provided to the card, and the 3.3VOUT and 1.5VOUT switches are turned off (Standby mode). If a card is present and all output voltages are being applied, then the 1.5VIN, or 3.3VIN is removed from the input of the power switch; the AUXOUT voltage is provided to the card and the 3.3VOUT and 1.5VOUT switches are turned off (Standby mode). If prior to the insertion of a card, the AUXIN is available at the input of the power switch and 3.3VIN and/or 1.5VIN are not, or if STBY is asserted (logic low), then no power is made available to the card (OFF mode). If 1.5VIN and 3.3VIN are made available at the input of the power switch after the card is inserted and STBY is not asserted, all the output voltages are made available to the card (Card Inserted mode). DISCHARGE FETs The discharge FETs on the outputs are activated whenever the device detects that a card is not present (No Card mode). Activation occurs after the input-to-output power switches are turned off (break before make). The discharge FETs de-activate if either of the card-present lines go active low, unless the SHDN pin is asserted. The discharge FETs are also activated whenever the SHDN input is asserted and stay asserted until SHDN is de-asserted.

An ExpressCard comes in two form factors defined as ExpressCard|34 or ExpressCard|54. The difference, as defined by the name, is the width of the module, 34 mm or 54 mm, respectively. Host systems supporting the ExpressCard module can support either the ExpressCard|34 or ExpressCard|54 or both. ExpressCard POWER REQUIREMENTS Regardless of which ExpressCard module is used, the power requirements as defined in the ExpressCard Standard apply to both on an individual slot basis. The host system is required to supply 3.3 V, 1.5 V, and AUX to each of the ExpressCard slots. However, the voltage is only applied after an ExpressCard is inserted into the slot. The ExpressCard connector has two pins, CPPE and CPUSB, that are used to signal the host when a card is inserted. If the ExpressCard module itself connects the CPPE to ground, the logic low level on that signal indicates to the host that a card supporting PCI Express has been inserted. If CPUSB is connected to ground, then the ExpressCard module supports the USB interface. If both PCI Express and USB are supported by the ExpressCard module, then both signals, CPPE and CPUSB, must be connected to ground. In addition to the Card Present signals (CPPE and CPUSB), the host system determines when to apply power to the ExpressCard module based on the state of the system. The state of the system is defined by the state of the 3.3 V, 1.5 V, and AUX input voltage rails. For the sake of simplicity, the 3.3-V and 1.5-V rails are defined as the primary voltage rails as oppose to the auxiliary voltage rail, AUX. ExpressCard POWER SWITCH OPERATION The ExpressCard power switch resides on the host, and its main function is to control when to send power to the ExpressCard slot. The ExpressCard power switch makes decisions based on the Card Present inputs and on the state of the host system as defined by the primary and auxiliary voltage rails. The following conditions define the operation of the host power controller: 1. When both primary power and auxiliary power at the input of the ExpressCard power switch are off, then all power to the ExpressCard connector is off regardless of whether a card is present. 2. When both primary power and auxiliary power at the input of the ExpressCard power switch are on, then power is only applied to the ExpressCard after the ExpressCard power switch detects that a card is present. 3. When primary power (either +3.3 V or +1.5 V) at the input of the ExpressCard power switch is off and auxiliary power at the input of the ExpressCard power switch is on, then the ExpressCard power switch behaves in the following manner: a. If neither of the Card Present inputs is detected (no card inserted), then no power is applied to the ExpressCard slot. b. If the card is inserted after the system has entered this power state, then no power is applied to the ExpressCard slot. c. If the card is inserted prior to the removal of the primary power (either +3.3 V or +1.5 V or both) at the input of the ExpressCard power switch, then only the primary power (both +3.3 V and +1.5 V) is removed and the auxiliary power is sent to the ExpressCard slot. Figure 18 through Figure 23 illustrate the timing relationships between power/logic inputs and outputs of ExpressCard.
