DSC-4856/8 IDT70V9389/289L High-Speed 3.3V 64K x18/x16 Dual-Port Synchronous Pipelined Static RAM Description: The IDT70V9389/289 is a high-speed 64K x 18 (64K x 16) bit synchronous Dual-Port 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 & Commercial Temperature Ranges With an input data register, the IDT70V9389/289 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 500mW of power.

Transition is measured 0mV from Low or High-impedance voltage with the Output Test Load (Figure 2). This parameter is guaranteed by device characterization, but is not production tested. 2. The Pipelined output parameters (tCYC2, tCD2) apply to either or both the Left and Right ports when FT/PIPE = VIH. Flow-through parameters (tCYC1, tCD1) apply when FT/PIPE = VIL for that port. 3. All input signals are synchronous with respect to the clock except for the asynchronous Output Enable (OE), FT/PIPER, and FT/PIPEL. 6.42 10 IDT70V9389/289L High-Speed 3.3V 64K x18/x16 Dual-Port Synchronous Pipelined Static RAM Industrial & Commercial Temperature Ranges Timing Waveform of Read Cycle for Flow-Through Output (FT/PIPE"X" = VIL)(3,7) tCYC1 tCH1 tCL1 CLK CE0 tSC tHC tSB tHB tSC tHC tSB tHB CE1 UB, LB R/W tSW tHW tSA ADDRESS (5) tHA An An + 1 tCD1 DATAOUT An + 3 tCKHZ (1) Qn tCKLZ OE An + 2 tDC Qn + 1 Qn + 2 (1) (1) tOHZ tDC tOLZ (1) (2) .. tOE 4856 drw 06 Timing Waveform of Read Cycle for Pipelined Operation (FT/PIPE"X" = VIH)(3,7) tCYC2 tCH2 tCL2 CLK CE0 tSC tSC tHC tHC (4) CE1 tSB tSB tHB R/W ADDRESS (5) tSW tHW tSA tHA An An + 1 (1 Latency) An + 2 An + 3 tDC tCD2 DATAOUT Qn (1) tCKLZ OE tHB (6) UB, LB Qn + 2(6) Qn + 1 tOHZ(1) tOLZ(1) (2) tOE 4856 drw 07 NOTES: 1. Transition is measured 0mV from Low or High-impedance voltage with the Output Test Load (Figure 2). 2. OE is asynchronously controlled; all other inputs are synchronous to the rising clock edge. 3. ADS = VIL 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. The diagram is with respect to that port. 6.42 11 IDT70V9389/289L High-Speed 3.3V 64K x18/x16 Dual-Port Synchronous Pipelined Static RAM Industrial & Commercial Temperature Ranges Timing Waveform of a Bank Select Pipelined Read(1,2) tCH2 tCYC2 tCL2 CLK tSA tHA A0 ADDRESS(B1) tSC tHC CE0(B1) tSC tHC Q0 DATAOUT(B1) tDC tCD2 Q3 Q1 tDC tCKLZ (3) tCKHZ (3) tHA A0 ADDRESS(B2) tCKHZ(3) tCD2 tCD2 tSA A6 A5 A4 A3 A2 A1 A6 A5 A4 A3 A2 A1 tSC tHC CE0(B2) tSC tHC tCD2 DATAOUT(B2) tCKHZ (3) Q2 tCKLZ(3) tCD2 tCKLZ (3) Q4 4856 drw 08 Timing Waveform with Port-to-Port Flow-Through Read(4,5,7) CLK "A" tSW tHW R/W "A" tSA ADDRESS "A" NO MATCH MATCH tSD DATAIN "A" tHA tHD VALID tCCS (6) CLK "B" tCD1 R/W "B" ADDRESS "B" tSW tHW tSA tHA NO MATCH MATCH tCWDD (6) tCD1 DATAOUT "B" VALID VALID tDC tDC 4856 drw 09 NOTES: 1.

ADDRESS(B1) = ADDRESS(B2) in this situation. 2. UB, LB, OE, and ADS = VIL; CE1(B1), CE1(B2), R/W 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 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. Port "A" may be either Left or Right port. Port "B" is the opposite from Port "A". 6.42 12 IDT70V9389/289L High-Speed 3.3V 64K x18/x16 Dual-Port Synchronous Pipelined Static RAM Industrial & Commercial Temperature Ranges Timing Waveform of Pipelined Read-to-Write-to-Read (OE = VIL)(3) tCYC2 tCH2 tCL2 CLK CE0 tSC tHC CE1 tSB tHB UB, LB tSW tHW R/W (4) ADDRESS tSW tHW An tSA tHA An +1 An + 2 An + 4 An + 3 An + 2 tSD tHD DATAIN Dn + 2 tCD2 (2) tCKHZ (1) (1) tCD2 tCKLZ Qn + 3 Qn DATAOUT READ NOP (5) WRITE READ 4856 drw 10 Timing Waveform of Pipelined Read-to-Write-to-Read (OE Controlled)(3) tCH2 tCYC2 tCL2 CLK CE0 tSC tHC CE1 tSB tHB UB, LB tSW tHW R/W (4) ADDRESS tSW tHW An tSA tHA An +1 An + 2 An + 3 An + 4 An + 5 tSD tHD DATAIN Dn + 3 Dn + 2 tCD2 (2) tCKLZ(1) tCD2 Qn DATAOUT Qn + 4 tOHZ(1) OE READ WRITE READ 4856 drw 11 NOTES: 1.

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. 6.42 15 IDT70V9389/289L High-Speed 3.3V 64K x18/x16 Dual-Port Synchronous Pipelined Static RAM Industrial & 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(7) 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 4856 drw 16 Timing Waveform of Counter Reset (Pipelined Outputs)(2) tCH2 tCYC2 tCL2 CLK tSA tHA An ADDRESS(4) INTERNAL(3) ADDRESS Ax (6) 0 1 An + 2 An + 1 An An + 1 tSW tHW R/W ADS tSAD tHAD CNTEN tSCN tHCN tSRST tHRST CNTRST tSD tHD D0 DATAIN DATAOUT(5) Q1 Q0 COUNTER RESET (6) WRITE ADDRESS 0 READ ADDRESS 0 READ ADDRESS 1 READ ADDRESS n Qn READ ADDRESS n+1 NOTES: 4856 drw 17 1. CE0, UB, LB, and R/W = VIL; CE1 and CNTRST = VIH. 2. 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. ADDR0 will be accessed. Extra cycles are shown here simply for clarification. 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 16 IDT70V9389/289L High-Speed 3.3V 64K x18/x16 Dual-Port Synchronous Pipelined Static RAM Industrial & Commercial Temperature Ranges Functional Description Depth and Width Expansion The IDT70V9389/289 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 staff 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 IDT70V9389/289's for depth expansion configurations. When the Pipelined output mode is enabled, two cycles are required with CE0 = VIL and CE1 = VIH to re-activate the outputs. The IDT70V9389/289 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 IDT70V9389/289 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 36/32-bit or wider applications.
