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 MAS-
TER/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 sepa-
rate control, 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 consum-
ing 200µW from a 2V battery.
The IDT7130/IDT7140 devices are packaged in 48-pin
sidebraze or plastic DIPs, LCCs, or flatpacks, 52-pin PLCC,
and 64-pin TQFP and STQFP. Military grade product is
manufactured in compliance with the latest revision of MIL-
STD-883, Class B, making it ideally suited to military tem-
perature applications demanding the highest level of per-
formance and reliability.
