M67025E  
8 K 16 CMOS Dual Port RAM Rad Tolerant  
Introduction  
The M67025E is a very low power CMOS dual port static Using an array of eight transistors (8T) memory cell, the  
RAM organised as 8192 × 16. The M67025E is designed M67025E combines an extremely low standby supply  
to be used as a stand-alone 16 bit dual port RAM or as a current (typ = 1.0 µA) with a fast access time at 30 ns  
combination MASTER/SLAVE dual port for 32 bit or over the full temperature range. All versions offer battery  
more width systems. The TEMIC MASTER/SLAVE dual backup data retention capability with a typical power  
port approach in memory system applications results in consumption at less than 5 µW.  
full speed, error free operation without the need of an  
additional discrete logic.  
The M67025E is processed according to the methods of  
the latest revision of the MIL STD 883 (class B or S), ESA  
Master and slave devices provide two independant ports  
with separate control, address and I/O pins that permit  
independant, asynchronous access for reads and writes to  
any location in the memory. An automatic power down  
feature controlled by CS permits the on-chip circuitry of  
each port in order to enter a very low stand by power  
mode.  
SCC 9000 or QML.  
Features  
D Fast access time : 30, 45 ns  
D Versatile pin select for master or slave :  
– M/S = H for busy output flag on master  
– M/S = L for busy input flag on slave  
D Wide temperature range :  
–55 °C to +125 °C  
D Separate upper byte and lower byte control for multiplexed  
D INT flag for port to port communication  
D Full hardware support of semaphore signaling between ports  
D Fully asynchronous operation from either port  
D Battery back-up operation : 2 V data retention  
D TTL compatible  
bus compatibility  
D Expandable data bus to 32 bits or more using master/slave  
chip select when using more than one device  
D On chip arbitration logic  
D Single 5 V ± 10 % power supply
