HYM72V8025/35GS-50/-60
8M x 72-ECC EDO-Module
The HYM 72V8025/35GS-50/-60 is a 64 MByte DRAM module organized as 8 388 608 words by 72-
bit in a 168-pin, dual read-out, single-in-line package comprising nine HYB3165805AJ/AT 8M × 8
DRAMs in 400 mil wide SOJ or TSOPII - 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 HYB3165805AJ/AT 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.
