DSC-4842/7 IDT709289L High-Speed 64K x 16 Synchronous Pipelined Dual-Port Static RAM Description The IDT709289 is a high-speed 64K x 16 bit synchronous DualPort RAM. The memory array utilizes Dual-Port memory cells to allow simultaneous access of any address from both ports. Registers on control, data, and address inputs provide minimal setup and hold times. The timing latitude provided by this approach allows systems to be designed with very short cycle times. Industrial and Commercial Temperature Ranges With an input data register, the IDT709289 has been optimized for applications having unidirectional or bidirectional data flow in bursts. An automatic power down feature, controlled by CE0 and CE1, permits the on-chip circuitry of each port to enter a very low standby power mode. Fabricated using CMOS high-performance technology, these devices typically operate on only 1.2W of power.

ADS = VIL, CNTEN and CNTRST = VIH. 4. The output is disabled (High-Impedance state) by CE0 = VIH, CE1 = VIL, UB = VIH, or LB = VIH following the next rising edge of the clock. Refer to Truth Table 1. 5. Addresses do not have to be accessed sequentially since ADS = VIL constantly loads the address on the rising edge of the CLK; numbers are for reference use only. 6. If UB or LB was HIGH, then the Upper Byte and/or Lower Byte of DATAOUT for Qn + 2 would be disabled (High-Impedance state). 7. "X" here denotes Left or Right port.

UB, LB, OE, and ADS = VIL; CE1(B1), CE1(B2), R/W, CNTEN, and CNTRST = VIH. 3. Transition is measured 0mV from Low or High-impedance voltage with the Output Test Load (Figure 2). 4. CE0, UB, LB, and ADS = VIL; CE1, CNTEN, and CNTRST = VIH. 5. OE = VIL for the Right Port, which is being read from. OE = VIH for the Left Port, which is being written to. 6. If tCCS < maximum specified, then data from right port READ is not valid until the maximum specified for tCWDD. If tCCS > maximum specified, then data from right port READ is not valid until tCCS + tCD1. tCWDD does not apply in this case. 7. All timing is the same for both Left and Right ports.

CE0, OE, UB, and LB = VIL; CE1, R/W, and CNTRST = VIH. 2. If there is no address change via ADS = VIL (loading a new address) or CNTEN = VIL (advancing the address), i.e. ADS = VIH and CNTEN = VIH, then the data output remains constant for subsequent clocks. 12 6.42 IDT709289L High-Speed 64K x 16 Synchronous Pipelined Dual-Port Static RAM Industrial and Commercial Temperature Ranges Timing Waveform of Write with Address Counter Advance (Flow-Through or Pipelined Outputs)(1) tCH2 tCYC2 tCL2 CLK tSA tHA An ADDRESS INTERNAL(3) ADDRESS An(7) An + 2 An + 1 An + 4 An + 3 tSAD tHAD ADS CNTEN tSD tHD Dn + 1 Dn DATAIN WRITE EXTERNAL ADDRESS Dn + 1 Dn + 4 Dn + 3 Dn + 2 WRITE WRITE WITH COUNTER COUNTER HOLD WRITE WITH COUNTER 4842 drw 17 Timing Waveform of Counter Reset (Pipelined Outputs)(2) tCH2 tCYC2 tCL2 CLK tSA tHA ADDRESS(4) INTERNAL(3) ADDRESS An Ax(6) 0 1 An + 2 An + 1 An + 1 An tSW tHW R/W ADS CNTEN tSRST tHRST CNTRST tSD tHD D0 DATAIN Qn Q1 Q0 DATAOUT(5) .

CE0, UB, LB = VIL; CE1 = VIH. 3. The "Internal Address" is equal to the "External Address" when ADS = VIL and equals the counter output when ADS = VIH. 4. Addresses do not have to be accessed sequentially since ADS = VIL constantly loads the address on the rising edge of the CLK; numbers are for reference use only. 5. Output state (High, Low, or High-impedance) is determined by the previous cycle control signals. 6. No dead cycle exists during counter reset. A READ or WRITE cycle may be coincidental with the counter reset cycle. 7. CNTEN = VIL advances Internal Address from ‘An’ to ‘An +1’. The transition shown indicates the time required for the counter to advance. The ‘An +1’ Address is written to during this cycle. 6.42 13 IDT709289L High-Speed 64K x 16 Synchronous Pipelined Dual-Port Static RAM Industrial and Commercial Temperature Ranges A Functional Description Depth and Width Expansion The IDT709289 provides a true synchronous Dual-Port Static RAM interface. Registered inputs provide minimal 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, however, the self-timed internal write pulse is independent of the LOW to HIGH transition of the clock signal. An asynchronous output enable is provided to ease asynchronous bus interfacing. Counter enable inputs are also provided to stall the operation of the address counters for fast interleaved memory applications. CE0 = VIH or CE1 = VIL for one clock cycle will power down the internal circuitry to reduce static power consumption. Multiple chip enables allow easier banking of multiple IDT709289's for depth expansion configurations. When the Pipelined output mode is enabled, two cycles are required with CE0 = VIL and CE1 = VIH to reactivate the outputs. The IDT709289 features dual chip enables (refer to Truth Table I) in order to facilitate rapid and simple depth expansion with no requirements for external logic. Figure 4 illustrates how to control the various chip enables in order to expand two devices in depth. The 709289 can also be used in applications requiring expanded width, as indicated in Figure 4. Since the banks are allocated at the discretion of the user, the external controller can be set up to drive the input signals for the various devices as required to allow for 32-bit or wider applications.
