The device is fabricated in SIEMENS/IBM most advanced first generation 64Mbit CMOS silicon gate process technology. The circuit and process design allow this device to achieve high performance and low power dissipation. The HYB3164(5)165 operates with a single 3.3 +/-0.3V power supply and interfaces with either LVTTL or LVCMOS levels. Multiplexed address inputs permit the HYB3164(5)165 to be packaged in a 500mil wide TSOPII-54 plastic package. These packages provide high system bit densities and are compatible with commonly used automatic testing and insertion equipment.The HYB3164(5)165TL parts have a very low power „sleep mode“ supported by Self Refresh.

Vih may overshoot to VV + 0.2V for pulse widths of < 4ns with 3.3V. Vil may undershoot to -2.0V for pulse width < 4.0 ns with 3.3V. Pulse width measured at 50% points with amplitude measured peak to DC reference. 2) ICC1, ICC3, ICC4 and ICC6 and ICC7 depend on cycle rate. 3) ICC1 and ICC4 depend on output loading. Specified values are measured with the output open. 4) Address can be changed once or less while RAS = Vil.In the case of ICC4 it can be changed once or less during a Hyper page mode cycle ( thpc). 5) An initial pause of 100 s is required after power-up followed by 8 RAS-only-refresh cycles, before proper device operation is achieved. In case of using internal refresh counter, a minimum of 8 CAS-before-RAS initialization cycles instead of 8 RAS cycles are required. 6) AC measurements assume tT = 2 ns. 7) VIH (min.) and VIL (max.) are reference levels for measuring timing of input signals. Also, transition times are measured between VIH and VIL. 8) Measured with the specified current load and 100 pF at Voh = 2.0 V and Vol = 0.8 V. 9) Operation within the tRCD (max.) limit ensures that tRAC (max.) can be met. tRCD (max.) is specified as a reference point only: If tRCD is greater than the specified tRCD (max.) limit, then access time is controlled by tCAC. 10) Operation within the tRAD (max.) limit ensures that tRAC (max.) can be met. tRAD (max.) is specified as a reference point only: If tRAD is greater than the specified tRAD (max.) limit, then access time is controlled by tAA. 11) Either tRCH or tRRH must be satisfied for a read cycle. 12) tOFF (max.) and tOEZ (max.) define the time at which the outputs achieve the open-circuit condition and are not referenced to output voltage levels. 13) Either tDZC or tDZO must be satisfied. 14) Either tCDD or tODD must be satisfied. 15) tWCS, tRWD, tCWD, tAWD and tCPWD are not restrictive operating parameters. They are included in the data sheet as electrical characteristics only. If tWCS > tWCS (min.), the cycle is an early write cycle and the I/O pin will remain open-circuit (high impedance) through the entire cycle; if tRWD > tRWD (min.), tCWD > tCWD (min.), tAWD > tAWD (min.) and tCPWD > tCPWD (min.) , the cycle is a read-write cycle and I/O pins will contain data read from the selected cells. If neither of the above sets of conditions is satisfied, the condition of the I/O pins (at access time) is indeterminate. 16) These parameters are referenced to CAS leading edge in early write cycles and to WRITE leading edge in Read-Modify-Write cycles. 17) When using Self Refresh mode, the following refresh operations must be performed to ensure proper DRAM operation: If row addresses are being refresh in an evenly distributed manner over the refresh interval using CBR refresh cycles, then only one CBR cycle must be performed immediatly after exit from Self Refresh. If row addresses are being refresh in any other manner (ROR - Distributed/Burst or CBR-Burst) over the refresh interval, then a full set of row refreshed must be performed immediately before entry to and immediatey after exit from Self Refresh Semiconductor Group 42 HYB3164(5)165T(L)-50/-60 4M x 16 EDO-DRAM tRC tRAS RAS V IH VIL tCSH V IH VIL tRAD tASR Address V IH VIL OE I/O (Inputs) tRAL tCAH tASC tASR Column Row Row tRCH tRAH WE tCRP tRSH tCAS tRCD UCAS LCAS tRP tRCS tRRH V IH VIL tAA tOEA V IH VIL tCDD tDZC tODD tDZO V IH tCAC VIL tCLZ V OH I/O (Outputs) V Hi Z tOFF tOEZ Valid Data Out Hi Z OL tRAC WL1 “H” or “L” Read Cycle Semiconductor Group 43 HYB3164(5)165T(L)-50/-60 4M x 16 EDO-DRAM tRC tRAS RAS V IH VIL tCSH tRCD UCAS LCAS VIL tRAD V IH OE Row tCAH tASR tCWL tWCS V IH .
