IDT7035S/L
High-Speed 8K x 18 Dual-Port Static RAM
Description
The IDT7035 is a high-speed 8K x 18 Dual-Port Static RAM. The
IDT7035 is designed to be used as a stand-alone 144K-bit Dual-Port RAM
or as a combination MASTER/SLAVE Dual-Port RAM for 36-bit or more
wordsystems. UsingtheIDTMASTER/SLAVEDual-PortRAMapproach
in 36-bit or wider memory system applications results in full-speed, error-
free operation without the need for additional discrete logic.
This device provides two independent ports with separate control,
address,andI/Opinsthatpermitindependent, asynchronousaccessfor
reads or writes to any location in memory. An automatic power down
feature controlled by Chip Enable (CE) permits the on-chip circuitry of each
Industrial and Commercial Temperature Ranges
port to enter a very low standby power mode.
The IDT7035 utilizes a 18-bit wide data path to alow for parity at the
user's option. This feature is especially useful in data communications
applications where it is necessary to use a parity bit for transmission/
reception error checking.
Fabricated using IDT’s CMOS high-performance technology, these
devices typically operate on only 800mW of power. Low-power (L)
versions offer battery backup data retention capability with typical power
consumption of 500µW from a 2V battery.
