IDT7130SA/LA and IDT7140SA/LA
High-Speed 1K x 8 Dual-Port Static SRAM
Military, Industrial and Commercial Temperature Ranges
Description
The IDT7130/IDT7140 are high-speed 1K x 8 Dual-Port Static
RAMs. The IDT7130 is designed to be used as a stand-alone 8-bit
Dual-Port RAM or as a "MASTER" Dual-Port RAM together with the
IDT7140 "SLAVE" Dual-Port in 16-bit-or-more word width systems.
Using the IDT MASTER/SLAVE Dual-Port RAM approach in 16-or-
more-bit memory system applications results in full-speed, error-
free operation without the need for additional discrete logic.
Both devices provide two independent ports with separate con-
trol, address, and I/O pins that permit independent asynchronous
access for reads or writes to any location in memory. An automatic
power down feature, controlled by
CE,
permits the on chip circuitry
of each port to enter a very low standby power mode.
Fabricated using IDT's CMOS high-performance tech-nology,
these devices typically operate on only 550mW of power. Low-
power (LA) versions offer battery backup data retention capability,
with each Dual-Port typically consuming 200µW from a 2V battery.
The IDT7130/IDT7140 devices are packaged in 48-pin sidebraze
or plastic DIPs, LCCs, flatpacks, 52-pin PLCC, and 64-pin TQFP
and STQFP. Military grade products are manufactured in compli-
ance 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 numbers indicates power rating (SA or LA).
2. PLCC and TQFP packages only.
3. At f = f
MAX
, address and control lines (except Output Enable) are cycling at the maximum frequency read cycle of 1/t
CYC
, and using AC TEST CONDITIONS of input levels
of GND to 3V.
4. f = 0 means no address or control lines change. Applies only to inputs at CMOS level standby.
5. Vcc = 5V, T
A
=+25°C for Typ and is not production tested. Vcc DC = 100 mA (Typ)
6. Port "A" may be either left or right port. Port "B" is opposite from port "A".
7. Industrial temperature: for other speeds, packages and powers contact your sales office.
