16 Megabit High Speed CMOS SRAM
DPS512C32MKV3
DESCRIPTION:
The DPS512C32MKV3 ‘’VERSA-STACK’’ module is a
revolutionary new high speed memory subsystem using
Dense-Pac Microsystems’ ceramic Stackable Leadless Chip
Carriers (SLCC) mounted on a co-fired ceramic substrate. It
offers 16 Megabits of SRAM in a package envelope of 1.190
x 1.190 x 0.250 inches.
The DPS512C32MKV3 contains four individual 512K x 8
SRAMs, packaged in their own hermetically sealed SLCCs
making the module suitable for commercial, industrial and
military applications.
By using SLCCs, the ‘’Versa-Stack’’ family of modules offers
a higher board density of memory than available with
conventional through-hole, surface mount, module, or
hybrid techniques.

NOTES:
1.
All voltages are with respect to V
SS
.
2. -2.0V min. for pulse width less than 20ns (V
IL
min. = -0.5V
at DC level).
3. Stresses greater than those under
ABSOLUTE MAXIMUM
RATINGS
may cause permanent damage to the device. This
is a stress rating only and functional operation of the device
at these or any other conditions above those indicated in
the operational sections of this specification is not implied.
Exposure to absolute maximum rating conditions for
extended periods may affect reliability.
30A141-02
REV. D
4. This parameter is guaranteed and not 100% tested.
5. Transition is measured at the point of
±500mV
from steady
state voltage.
6. When OE and CE are LOW and WE is HIGH, I/O pins are
in the output state,and input signals of opposite phase to
the outputs must not be applied.
7. The outputs are in a high impedance state when WE is
LOW.
8. CE and WE can initiate and terminate WRITE Cycle.
