DSC-34948 IDT709149S High-Speed 36K (4K x 9-bit) Synchronous Pipelined Dual-Port Static RAM 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. Industrial and Commercial Temperature Ranges 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 CMOS high-performance technology, these DualPorts 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.

Registered inputs provide very short set-up and hold times on address, data, and all critical control inputs. All internal registers are clocked on the rising edge of the clock signal. An asynchronous output enable is provided to ease asynchronous bus interfacing. The internal write pulse width is dependent only on the low to high transitions of the clock signal to initiate a write allowing the shortest Industrial and Commercial Temperature Ranges possible realized cycle times. Clock enable inputs are provided to stall the operation of the address and data input registers without introducing clock skew for very fast interleaved memory applications. A HIGH on the CE input for one clock cycle will power down the internal circuitry to reduce static power consumption. When piplelined mode is enabled, two cycles are required with CE LOW to reactivate the outputs.

'H' = HIGH voltage level steady state, 'h' = HIGH voltage level one set-up time prior to the LOW-to-HIGH clock transition, 'L' = LOW voltage level steady state 'l' = LOW voltage level one set-up time prior to the LOW-to-HIGH clock transition, 'X' = Don't care, 'NC' = No change 2. CLKEN = VIL must be clocked in during Power-Up. 3. Control signals are initialted and terminated on the rising edge of the CLK, depending on their input level. When R/W and CE are LOW, a write cycle is initiated on the LOWto-HIGH transition of the CLK. Termination of a write cycle is done on the next LOW-to-HIGH transistion of the CLK. 4. The register outputs are internal signals from the register inputs being clocked in or disabled by CLKEN. 9 6.42 IDT709149S High-Speed 36K (4K x 9-bit) Synchronous Pipelined Dual-Port Static RAM Ordering Information XXXX A 999 A Device Type Power Speed Package A A Industrial and Commercial Temperature Ranges A Process/ Temperature Range Blank 8 Tube or Tray Tape and Reel Blank I(1) Commercial (0°C to +70°C) Industrial (-40°C to +85°C) G(2) Green PF 80-pin TQFP (PN80) 8 10 12 Commercial Only Commercial & Industrial Commercial Only S Standard Power Speed in nanoseconds 709149 36K (4K x 9-Bit) Synchronous Pipelined Dual-Port RAM NOTES: 1.
