DESCRIPTION:
IDT7054S/L
PRELIMINARY
FEATURES:
• High-speed access
— Military: 20/25/35/45ns (max.)
— Commercial: 15/20/25/35/45ns (max.)
• Low-power operation
— IDT7054S
Active: 750mW (typ.)
Standby: 10mW (typ.)
— IDT7054L
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:
P1, P2, P3, P4
• 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
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.
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
FourPort RAM location.
The IDT7054 provides four 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. 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.
