CAS-before-RAS refresh, RAS-only-refresh, Self Refresh 4 decoupling capacitors mounted on substrate All inputs, outputs and clock fully TTL compatible 72 pin, dual read-out, one bank, Small Outline DIMM Module Utilizes four 8 -DRAMs (HYB 3165800T) 4096 refresh cycles 64 ms Gold contact pad

The HYM a 32 MByte DRAM module organized 388 608 words a 72-pin, dual read-out, small outline package comprising four HYB 8 DRAMs in 500 mil wide TSOPII-34 - packages mounted together with four 0.2 F ceramic decoupling capacitors a PC board. Each HYB 3165800T 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 density and speed of the module can be detected by the use of presence detect pins. These modules are ideal for portable systems applications where high memory capacity is needed. Ordering Information Type HYM 328000GD -50 HYM 328000GD -60 Pin Names CAS3 WE Vcc Vss - PD7 N.C.
