DESCRIPTION:
•
8K x 16-bit dual port RAM
- Stand Alone
- Master Slave
RAD-PAK® radiation-hardened against natural space
radiation
Maxwell Technologies’ 7025E Dual Port RAM High Speed
CMOS® microcircuit features a greater than 100 krad (Si) total
dose tolerance, depending upon space mission. The 7025E is
designed to be used as a stand-alone 128k-bit Dual Port RAM
or as a combination MASTER/SLAVE Dual-Port RAM for 32-
bit or more word systems. This design results in full-speed,
error-free operation without the need for additional discrete
logic. The 7025E provides two independent ports with sepa-
rate control, address, and I/O pins that permit independent,
asynchronous access for reads or writes to any location in
memory. An automatic power down feature controlled by CS
permits the on-chip circuitry of each port to enter a very low
standby power mode.

•
Total dose hardness:
- > 100 krad (Si), depending upon space mission
Excellent Single Event Effects:
-SELTH LET = >100 MeV/mg/cm2
-SEUTH LET = 7 MeV/mg/cm2
Package:
-84 Pin RAD-PAK® quad flat pack
Separate upper byte and lower byte control for multiplexed
bus compatibility
•
•
•
•
High speed access time: 35/45 ns
Expandable to 32 bits or more using master/slave select
when cascading
High speed CMOS technology
-TTL compatible, single 5V power supply
-Interrupt flag for port-to-port communication
-On chip port arbitration logic
-Asynchronous operation from either port
Maxwell Technologies' patented RAD-PAK® packaging technol-
ogy incorporates radiation shielding in the microcircuit pack-
age. It eliminates the need for box shielding while providing
the required radiation shielding for a lifetime in orbit or space
mission. In a GEO orbit, RAD-PAK provides greater than 100
krad (Si) radiation dose tolerance. This product is available
with screening up to Class S.

FIGURE 8. TIMING WAVEFORM OF WRITE WITH BUSY (FOR SLAVE)
1. R/W must be high during all address transitions.
2. A write occurs during the overlap (tSW to tWF) of a low CS or SEM and a low R/W.
3. T.WF is measured from the earlier of CS or R/W (or SEM or R/W) going high to the end of write cycle.
4. During this period, the I/O pins are in the output state, and input signals must not be applied.
5. If the CS or SEM low transition occurs simultaneously with or after the R/W low transition, the outputs remain in the
high impedance state.
6. Transitions measured = 500 mV from steady state with a 5 pF load (including scope and jig). This parameter is sam-
ple and not 100% tested.
7. If OE is low during a R/W controlled write cycle, the write pulse width must be the larger of two or (tWZ +tDW) to allow
the I/O driver to turn off and data to be placed on the bus for the required tDW. If OE is high during an R/W controlled
write cycle, this requirement does not apply and the write pulse can be as short as the specified tWP
.
8. To access RAM, CS = VIL, SEM = VIH.
9. To access upper byte, CS = VIL, UB = VIL, SEM = VIH.
To access lower byte, CS = VIL, LB = VIL, SEM = VIH.

3. This parameter is measured from the point where R/WA or SEMA goes high until R/WB or SEMB goes high.
