MOSEL VITELIC PRELIMINARY V437432S24V 3.3 VOLT 32M x 72 HIGH PERFORMANCE PC133 UNBUFFERED SDRAM ECC MODULE Features Description ■ 168 Pin Unbuffered ECC 33,554,432 x 72 bit Oganization SDRAM Modules ■ Utilizes High Performance 32M x 8 SDRAM in TSOPII-54 Packages ■ Fully PC Board Layout Compatible to INTEL’S Rev 1.0 Module Specification ■ Single +3.3V (± 0.3V) Power Supply ■ Programmable CAS Latency, Burst Length, and Wrap Sequence (Sequential & Interleave) ■ Auto Refresh (CBR) and Self Refresh ■ All Inputs, Outputs are LVTTL Compatible ■ 8192 Refresh Cycles every 64 ms ■ Serial Present Detect (SPD) ■ SDRAM Performance The V437432S24V memory module is organized 33,554,432 x 72 bits in a 168 pin dual in line memory module (DIMM). The 32M x 72 unbuffered DIMM uses 9 Mosel-Vitelic 32M x 8 ECC SDRAM. The x72 modules are ideal for use in high performance computer systems where increased memory density and fast access times are required.

The specified values are valid when addresses are changed no more than once during t CK(min.) and when No Operation commands are registered on every rising clock edge during t RC(min). Values are shown per module bank. 2. The specified values are valid when data inputs (DQ’s) are stable during t RC(min.). 3. All AC characteristics are shown for device level. An initial pause of 100 µs is required after power-up, then a Precharge All Banks command must be given followed by 8 Auto Refresh (CBR) cycles before the Mode Register Set Operation can begin. 4. AC timing tests have VIL = 0.4V and V IH = 2.4V with the timing referenced to the 1.4V crossover point. The transition time is measured between VIH and VIL. All AC measurements assume tT = 1 ns with the AC output load circuit shown. Specific tac and toh parameters are measured with a 50 pF only, without any resistive termination and with a input signal of 1V / ns edge rate between 0.8V and 2.0V. + 1.4 V tCH 2.4V CLOCK 50 Ohm 0.4V tCL tSETUP Z=50 Ohm tT I/O tHOLD 50 pF 1.4V INPUT tAC tAC tLZ I/O tOH 50 pF 1.4V OUTPUT Measurement conditions for tac and toh tHZ 5. If clock rising time is longer than 1 ns, a time (tT/2 -0.5) ns has to be added to this parameter. 6. Rated at 1.5V 7. If tT is longer than 1 ns, a time (tT -1) ns has to be added to this parameter. 8. Any time that the refresh Period has been exceeded, a minimum of two Auto (CBR) Refresh commands must be given to “wake-up” the device. 9. Self Refresh Exit is a synchronous operation and begins on the 2nd positive clock edge after CKE returns high. Self Refresh Exit is not complete until a time period equal to tRC is satisfied once the Self Refresh Exit command is registered. 10. Referenced to the time which the output achieves the open circuit condition, not to output voltage levels. 11. tDAL is equivalent to t DPL + tRP.
