Each HYB 5118165BSJ is described in the data sheet and is fully electrically tested and processed according to Siemens standard quality procedure prior to module assembly. After assembly onto the board, a further set of electrical tests is performed. The speed of the module can be detected by the use of presence detect pins. The common I/O feature on the HYM 321005S/GS-50/-60 dictates the use of early write cycles.

Vil may undershoot to -2.0 V for pulse width of less than or equal to 4 ns. Pulse width is measured at 50% points with amplitude measured peak to the DC reference. 2) ICC1, ICC3, ICC4 and ICC6 depend on cycle rate. 3) ICC1 and ICC4 depend on output loading. Specified values are obtained with the output open. 4) Address can be changed once or less while RAS = Vil. In case of ICC4 it can be changed once or less during a hyper page mode (EDO) cycle. 5) An initial pause of 200 s is required after power-up followed by 8 RAS cycles of which at least one cycle has to be a refresh cycle, before proper device operation is achieved. In case of using the 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. Transition times are also measured between VIH and VIL. 8) Measured with the specified current load and 100 pF at Vol = 0.8 V and Voh = 2.0 V. Access time is determined by the latter of t RAC, tCAC, tAA,tCPA. t CAC is measured from tristate. . 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.) define the time at which the output achieves the open-circuit conditions and are not referenced to output voltage levels. tOFF is referenced from the rising edge of RAS or CAS, whichever occurs last. 13) tWCS is not a restrictive operating parameter. This is included in the data sheet as electrical characteristics only. If tWCS > tWCS (min.) , the cycle is an early write cycle and data out pin will remain open-circuit (high impedance) through the entire cycle. 14) These parameters are referenced to the CAS leading edge.
