DESCRIPTION The WV3EG32M64ETSU is a 32Mx64 Double Data Rate SDRAM memory module based on 256Mb DDR SDRAM components. The module consists of eight 32Mx8 DDR SDRAMs in 66 pin TSOP packages mounted on a 184 pin substrate. Synchronous design allows precise cycle control with the use of system clock. Data I/O transactions are possible on both edges and Burst Lengths allow the same device to be useful for a variety of high bandwidth, high performance memory system applications.

Includes ± 25mV margin for DC offset on VREF, and a combined total of 50mV margin for all AC noise and DC offset on VREF, bandwidth limited to 20MHz. The DRAM must accommodate DRAM current spikes on VREF and internal DRAM noise coupled to VREF, both of which may result in VREF noise. VREF should be de-coupled with an inductance of 3nH. 2. VTT is not applied directly to the device. VTT is a system supply for signal termination resistors, is expected to be set equal to VREF, and must track variations in the DC level of VREF. 3. VID is the magnitude of the difference between the input level on CK and the input level on CK#. 4. These parameters should be tested at the pin on actual components and may be checked at either the pin or the pad in simulation. The AC and DC input specifications are relative to a VREF envelop that has been bandwidth limited to 200MHZ. 5. The value of VIX is expected to equal 0.5*VCCQ of the transmitting device and must track variations in the DC level of the same.

The maximum limit for this parameter is not a device limit. The device will operate with a greater value for this parameter, but system performance (bus turnaround) will degrade accordingly. The specific requirement is that DQS be valid (HIGH, LOW, or at some point on a valid transition) on or before this CK edge. A valid transition is defined as monotonic and meeting the input slew rate specifications of the device. when no writes were previously in progress on the bus, DQS will be tran sitioning from High- Z to logic LOW. If a previous write was in progress, DQS could be HIGH, LOW, or transitioning from HIGH to LOW at this time, depending on tDQSS. A maximum of eight AUTO REFRESH commands can be posted to any given DDR SDRAM device. For command/address input slew rate: 1.0 V/ns For command/address input slew rate: 0.5 V/ns and 1.0 V/ns For CK & CK# slew rate 1.0 V/ns These parameters guarantee device timing, but they are not necessarily tested on each device. They may be guaranteed by device design or tester correlation. Slew Rate is measured between VOH(ac) and VOL(ac). WV3EG32M64ETSU-D3 ADVANCED 2. 10. Min (tCL, tCH) refers to the smaller of the actual clock low time and the actual clock high time as provided to the device (i.e. this value can be greater than the minimum specification limits for tCL and tCH).....For example, tCL and tCH are = 50% of the period, less the half period jitter (tJIT(HP)) of the clock source, and less the half period jitter due to crosstalk (tJIT(crosstalk)) into the clock traces. 11. tQH = tHP - tQHS, where: tHP = minimum half clock period for any given cycle and is defined by clock high or clock low (tCH, tCL). tQHS accounts for 1) The pulse duration distortion of on-chip clock circuits; and 2) The worst case push-out of DQS on one tansition followed by the worst case pull-in of DQ on the next transition, both of which are, separately, due to data pin skew and output pattern effects, and pchannel to n-channel variation of the output drivers. 12. tDQSQ Consists of data pin skew and output pattern effects, and p-channel to n-channel variation of the output drivers for any given cycle. 13. tDAL = (tWR/tCK) + (tRP/tCK) For each of the terms above, if not already an integer, round to the next highest integer. Example: For DDR266B at CL=2.5 and tCK=7.5ns tDAL = (15 ns / 7.5 ns) + (20 ns/ 7.5ns) = (2) + (3) tDAL = 5 clocks 3. 4. 5. 6. 7. 8. 9.
