IDT7054S/L  
PRELIMINARY  
HIGH-SPEED  
4K X 8 FOURPORT™  
STATIC RAM  
Integrated Device Technology, Inc.  
FEATURES:  
DESCRIPTION:  
• High-speed access  
The IDT7054 is a high-speed 4K x 8 FourPort Static RAM  
designed to be used in systems where multiple access into a  
common RAM is required. This FourPort Static RAM offers  
increased system performance in multiprocessor systems  
that have a need to communicate in real time and also offers  
added benefit for high-speed systems in which multiple  
access is required in the same cycle.  
— Military: 20/25/35/45ns (max.)  
— Commercial: 15/20/25/35/45ns (max.)  
• Low-power operation  
— IDT7054S  
Active: 750mW (typ.)  
Standby: 10mW (typ.)  
— IDT7054L  
The IDT7054 is also designed to be used in systems where  
on-chip hardware port arbitration is not needed. This part  
lends itself to those systems which cannot tolerate wait states  
or are designed to be able to externally arbitrate or withstand  
contention when all ports simultaneously access the same  
Active: 750mW (typ.)  
Standby: 1.5mW (typ.)  
• True Four-Port memory cells which allow simultaneous  
reads of the same memory locations  
• Fully asynchronous operation from each of the four ports: FourPort RAM location.  
P1, P2, P3, P4  
The IDT7054 provides four independent ports with sepa-  
• Battery backup operation—2V data retention  
• TTL-compatible; single 5V (±10%) power supply  
• Available in several popular hermetic and plastic  
packages for both through-hole and surface mount  
• Military product compliant to MIL-STD-883, Class B  
• Industrial temperature range (–40°C to +85°C) is avail-  
able, tested to military electrical specifications  
rate control, address, and I/O pins that permit independent,  
asynchronous access for reads or writes to any location in  
memory. It is the user’s responsibility to ensure data integrity  
when simultaneously accessing the same memory location  
from all ports. An automatic power down feature, controlled  
by CE, permits the on-chip circuitry of each port to enter a very  
low power standby power mode.
