DSC 4831/8 IDT70V3569S High-Speed 16K x 36 Dual-Port Synchronous Pipelined Static RAM Industrial and Commercial Temperature Ranges Description: The IDT70V3569 is a high-speed 16K x 36 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. With an input data register, the IDT70V3569 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. The 70V3569 can support an operating voltage of either 3.3V or 2.5V on one or both ports, controllable by the OPT pins. The power supply for the core of the device (VDD) remains at 3.3V.

CE0, BEn, and R/W = VIL; CE1 and CNTRST = VIH. 2. CE0, BEn = 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: ADDR 0 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 IDT70V3569S High-Speed 16K x 36 Dual-Port Synchronous Pipelined Static RAM Industrial and Commercial Temperature Ranges Functional Description The IDT70V3569 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. A HIGH on CE0 or a LOW on CE1 for one clock cycle will power down the internal circuitry to reduce static power consumption. Multiple chip enables allow easier banking of multiple IDT70V3569s for depth expansion configurations. Two cycles are required with CE0 LOW and CE1 HIGH to re-activate the outputs. Depth and Width Expansion The IDT70V3569 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 IDT70V3569 can also be used in applications requiring expanded width, as indicated in Figure 4. Through combining the control signals, the devices can be grouped as necessary to accommodate applications needing 72-bits or wider.
