HYM72V1625/35GS-50/-60
16M x 72-ECC EDO-Module
The HYM 72V1625/35GS-50/-60 is a 128 MByte DRAM module organized as 16 777 216 words by
72-bit in a 168-pin, dual read-out, single-in-line package comprising eighteen HYB 3164405AT/AJ
16M
×
4 EDO-DRAMs in 400 mil wide TSOPII or SOJ- packages mounted together with ceramic
decoupling capacitors on a PC board. All inputs except RAS and DQ are buffered by using
BiCMOS buffers/line drivers.
Each HYB 3164405AT/AJ 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.
