IDT70121/IDT70125
High-Speed 2K x 9 Dual-Port Static RAM with Busy & Interrupt
Industrial and Commercial Temperature Ranges
Description
The IDT70121/IDT70125 are high-speed 2K x 9 Dual-Port Static
RAMs. The IDT70121 is designed to be used as a stand-alone 9-bit Dual-
Port RAM or as a “MASTER” Dual-Port RAM together with the IDT70125
“SLAVE” Dual-Port in 18-bit-or-more word width systems. Using the IDT
MASTER/SLAVE Dual-Port RAM approach in 18-bit-or-wider 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 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.
The IDT70121/IDT70125 utilizes a 9-bit wide data path to allow for
Data/Controlandparitybitsattheuser’soption. Thisfeatureisespecially
useful in data communications applications where it is necessary to use a
parity bit for transmission/reception error checking.
Fabricated using CMOS high-performance technology, these
devices typically operate on only 675mW of power. Low-power (L)
versions offer battery backup data retention capability with each port
typically consuming 200µW from a 2V battery.
The IDT70121/IDT70125 devices are packaged in a 52-pin PLCC.
