The IDT71V321/IDT71V421 are high-speed 2K x 8 Dual-Port
Static RAMs with internal interrupt logic for interprocessor communica-
tions. The IDT71V321 is designed to be used as a stand-alone 8-bit
Dual-Port RAMor as a "MASTER" Dual-Port RAMtogether with the
IDT71V421 "SLAVE" Dual-Port in 16-or-more-bit memory systemap-
plications results in full speed, error-free operation without the need for
additional discrete logic.
The device provides two independent ports with separate control,
address, and I/O pins that permt independent, asynchronous access
for reads or writes to any location in memory. An automatic power
down feature, controlled by
CE
, permts the on chip circuitry of each
port to enter a very low standby power mode.
Fabricated using IDT's CMOS high-performance technology, these
devices typically operate on only 325mW of power. Low-power (L)
versions offer battery backup data retention capability, with each Dual-
Port typically consumng 200μW froma 2V battery.
The IDT71V321/IDT71V421 devices are packaged in a 52-pin
PLCC, a 64-pin TQFP (thin quad flatpack), and a 64-pin STQFP
(super thin quad flatpack).
