IDT709149S
High-Speed 36K (4K x 9-bit) Synchronous Pipelined Dual-Port Static RAM
Industrial and Commercial Temperature Ranges
Description
The IDT709149 is a high-speed 4K x 9 bit synchronous Dual-Port
SRAM. The memory array is based on Dual-Port memory cells to allow
simultaneous access from both ports. Registers on control, data, and
address inputs provide low set-up and hold times. The timing latitude
provided by this approach will allow systems to be designed with very short
cycle times. This device has been optimized for applications having
unidirectional data flow or bi-directional data flow in bursts, by utilizing input
data registers.
The IDT709149 utilizes a 9-bit wide data path to allow for parity at the
user's option. This feature is especially useful in data communication
applications where it is necessary to use a parity bit for transmission/
reception error checking.
Fabricated using IDT’s CMOS high-performance technology, these
Dual-Ports typically operate on only 800mW of power at maximum high-
speed clock-to-data output times as fast as 8ns. 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 IDT709149 is packaged in an 80-pin TQFP.
