DSC-5638/6 IDT70V9359/49L High-Speed 3.3V 8/4K x 18 Dual-Port Synchronous Pipelined Static RAM Description: The IDT70V9359/49 is a high-speed 8/4K x 18 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 and Commercial Temperature Ranges With an input data register, the IDT70V9359/49 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 IDT’s CMOS high-performance technology, these devices typically operate on only 450mW of power.

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.

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 14 IDT70V9359/49L High-Speed 3.3V 8/4K x 18 Dual-Port Synchronous Pipelined Static RAM Industrial and Commercial Temperature Ranges Functional Description Depth and Width Expansion The IDT70V9359/49 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 = VIL and CE1 = VIH for one clock cycle will power down the internal circuitry to reduce static power consumption. Multiple chip enables allow easier banking of multiple IDT70V9359/49'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 IDT70V9359/49 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 varioius chip enables in order to expand two devices in depth. The IDT70V9359/49 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-bit or wider applications.
