7025E  
(8K x 16-Bit) Dual Port RAM  
High-Speed CMOS  
Logic Diagram  
FEATURES:  
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.
