System Reset input – active low, logic level signal. Internally pulled
up to AUXIN. This input is driven by the host system and directly
affects PERST#. Asserting SYSRST# (logic low) forces PERST# to
assert. RCLKEN is not affected by the assertion of SYSRST#.

Shutdown input – active low, logic level signal. Internally pulled up

FUNCTION
G
YCG
Standby input – active low, logic level signal. Internally pulled up to
AUXIN. When asserted (logic low) after the card is inserted, this
input places the power switch in standby mode by turning off the
3.3V and 1.5V power switches and keeping the AUX switch on. If
the signal is asserted prior to the card being present, STBY#
places the power switch in OFF Mode by turning off the AUX, 3.3V,
and 1.5V power switches.
STBY#

I(*)
A logic level power good (with delay). When powered up, this
output remains asserted (logic level low) until all power rails are
within the tolerance. Once all power rails are within the tolerance
and RCLKEN has been released (logic high), PERST# is de-
asserted (logic high) after a time delay, as shown in the parametric
table. When powered down, this output is asserted whenever any
of the power rails drops 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.
PERST#

O
The host can also place the ExpressCard module in a reset state
by asserting a system reset SYSRST#. This system reset
generates a PERST# signal to the ExpressCard module without
disrupting the voltage rails. This is normally called a warm reset.
However, in a cold start situation, the system reset can also be
used to prolong the assertion time of PERST#.
Card Present input for USB cards. Internally pulled up to AUXIN. A
logic low level on this input indicates that the card present supports
the USB functions. When a card is inserted, CPUSB# is physically
connected to ground if the card supports USB functions.

FUNCTION
G
Reference Clock Enable signal. As an output, it is a logic level
power good to the host (no delay – open drain). As an input, if the
signal is kept inactive (low) by the host, PERST# will be prevented
from being de-asserted. Internally pulled up to AUXIN. This pin
serves both as an input and an output. When powered up, a
discharge FET keeps this signal at a low state as long as any of the
output power rails is out of their tolerance range. Once all output
power rails are within the tolerance, the switch releases RCLKEN,
allowing it to transit to a high state (internally pulled up to AUXIN).
RCLKEN
19
18 I(*)/O
The transition of RCLKEN from a low to a high state starts an
internal timer for the purpose of de-asserting 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.
Over current status output (open drain). This pin is an open-drain
output. When any of the three power switches (AUX, 3.3V, and
1.5V) is in an over current 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.
Primary voltage source, 3.3V input for 3.3VOUT
Secondary voltage source, 1.5V input for 1.5VOUT
Auxiliary voltage source, AUX input for AUXOUT and chip power.

(1) For input voltages, On means the respective input voltage is higher than its turn on threshold voltage; otherwise, the
voltage is Off (for AUX input, Off means the voltage is close to zero volt).
(2) For output voltages, On means the respective power switch is turned on so the input voltage is connected to the output;
Off means the power switch and its output discharge FET are both off; Gnd means the power switch is off but the output
discharge FET is on so the voltage on the output is pulled down to 0 V.
(3) Mode assigns each set of input conditions and respective output voltage results to a different name. These modes are
referred to as input conditions in the following Truth Table for Logic Outputs.
(4) CP# = CPUSB# and CPPE# equal to 1 when both CPUSB# and CPPE# signals are logic high, or equal to 0 when either
CPUSB# or CPPE# is low.
(5) STBY# is asserted (logic low) prior to the card being present.
(6) STBY# is asserted (logic low) prior to the voltage inputs being present.
(7) The card is inserted prior to the removal of the Primary or Secondary power (either 3.3VIN or 1.5VIN or both) at the input
of the ExpressCard power switch, then only the primary and secondary power (both 3.3VOUT and 1.5VOUT) are
removed and the auxiliary power is sent to the ExpressCard slot.

(1) RCLKEN as a logic input in this column. RCLKEN is an I/O pin and it can be driven low externally, left open, or
connected to high-impedance terminals, such as the gate of a MOSFET. It must not be driven high externally.

Note.1: According to the electrical specifications of ExpressCard Standard, the minimum propagation
delay time of e (Power stable to PERST# inactive) is 1ms.
Note.2: RCLKEN could be treated as a power good signal when card power is over 86% of nominal
voltage.
Note.3: The propagation delay time of c is SYSRST# assertion to PERST# assertion. The propagation
delay time of d is card power is under 86% of nominal voltage to RCLKEN de-assertion.
Note 4: RCLEKN de-assertion is prior to PERST# assertion when card power lost in any situation.
