STPC ATLAS
Issue 1.1 - March 23, 2004
45/109
4. ELECTRICAL SPECIFICATIONS
4.1. INTRODUCTION
The electrical specifications in this chapter are
valid for the STPC Atlas.
4.2. ELECTRICAL CONNECTIONS
4.2.1.
POWER/GROUND
CONNECTIONS/
DECOUPLING
Due to the high frequency of operation of the
STPC Atlas, it is necessary to install and test this
device using standard high frequency techniques.
The high clock frequencies used in the STPC
Atlas and its output buffer circuits can cause
transient power surges when several output
buffers switch output levels simultaneously. These
effects can be minimized by filtering the DC power
leads with low-inductance decoupling capacitors,
using low impedance wiring, and by utilizing all of
the VSS and VDD pins.
4.2.2. UNUSED INPUT PINS
No unused input pin should be left unconnected
unless they have an integrated pull-up or pull-
down. Connect active-low inputs to VDD through a
20 k
(±10%) pull-up resistor and active-high
inputs to VSS. For bi-directionnal active-high
inputs, connect to VSS through a 20 k
(±10%)
pull-up resistor to prevent spurious operation.
4.2.3. RESERVED DESIGNATED PINS
Pins designated as reserved should be left dis-
connected. Connecting a reserved pin to a pull-up
resistor, pull-down resistor, or an active signal
could cause unexpected results and possible
circuit malfunctions.
4.3. ABSOLUTE MAXIMUM RATINGS
The following table lists the absolute maximum
ratings for the STPC Atlas device. Stresses
beyond those listed under Table 4-1 limits may
cause permanent damage to the device. These
are stress ratings only and do not imply that
operation under any conditions other than those
specified in section "Operating Conditions".
Exposure to conditions beyond those outlined in
Table 4-1 may (1) reduce device reliability and (2)
result in premature failure even when there is no
immediately apparent sign of failure. Prolonged
exposure to conditions at or near the absolute
maximum ratings (Table 4-1) may also result in
reduced useful life and reliability.
4.3.1. 5V TOLERANCE
The STPC is capable of running with I/O systems
that operate at 5 V such as PCI and ISA devices.
Certain pins of the STPC tolerate inputs up to
5.5 V. Above this limit the component is likely to
sustain permanent damage.
All 5 volt tolerant pins are outlined in Table 2-3
Note 1: The figures specified apply to the Tcase of a
STPC device that is soldered to a board, as detailed in
the Design Guidelines Section, for Commercial and In-
dustrial temperature ranges.
