64 Megabit High Speed CMOS SRAM
DPS2MK32MKV3
PRELIMINARY
DESCRIPTION:
The DPS2MK32MKV3 ‘’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 64 Megabits of SRAM in a package envelope of 1.190 x
1.190 x 0.660 inches.
The DPS2MK32MKV3 contains sixteen 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.

REV. A
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.
