Description
The IDT7052 is a high-speed 2K 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 IDT7052 is also designed to be used in systems where on-chip
hardware port arbitration is not needed. This part lends itself to those

INDEX
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 IDT7052 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.
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 IDT7052 is packaged in a ceramic 108-pin Pin Grid Array (PGA),
120-pin Thin Quad Flatpack (TQFP) and 132-pin Plastic Quad Flatpack
(PQF). Military grade product is manufactured in compliance with the latest
revision of MIL-PRF-38535 QML, making it ideally suited to military
temperature applications demanding the highest level of performance and
reliability.

NOTES:
1. 'X' in part number indicates power rating (S or L).
2. V
CC
= 5V, T
A
= +25C and are not production tested.
3. f = 0 means no address or control lines change.
4. At f = f
MAX
,
address and control lines (except Output Enable) are cycling at the maximum frequency read cycle of 1/t
RC
, and using "AC Test Conditions" of input
levels of GND to 3V.
5. For the case of one port, divide the appropriate current above by four.
6. Industrial temperature: for specific speeds, packages and powers contact your sales office.
