Description
The IDT7054 is a high-speed 4K x 8 FourPortTM 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.
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

IDT7054S/L
High-Speed 4K x 8 FourPortTM Static RAM Military, Industrial and Commercial Temperature Ranges
2
Fabricated using IDT's CMOS high-performance technology, this
FourPort SRAM typically operates on only 750mW of power. Low-power
(L) versions offer battery backup data retention capability, with each port
typically consuming 50W from a 2V battery.
The IDT7054 is packaged in a ceramic 108-pin Pin Grid Array (PGA)
and a 128-pin Thin Quad Flatpack (TQFP). The military grade product
is manufactured in compliance with the latest revision of MIL-PRF-38535
QML, making it ideally suited to military temperature applications demand-
ing the highest level of performance and reliability.
externally arbitrated or withstand contention when all ports simultaneously
access the same FourPort RAM location.
The IDT7054 provides four independent ports with separate 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.
NOTES:
1. All V
CC
pins must be connected to the power supply.
2. All GND pins must be connected to the ground supply.
3. Package body is approximately 1.21 in x 1.21 in x .16 in.
4. This package code is used to reference the package diagram.
5. This text does not indicate orientation of the actual part-marking.
