HYM 324025S/GS-50/-60
4M x 32-Bit EDO-Module
The HYM 324025S/GS-50/-60 is a 16 MByte DRAM module organized as 4 194 304 words by
32-bit in a 72-pin single-in-line package comprising eight HYB 5117405BJ 4M x 4 DRAMs in 300
mil wide SOJ-packages mounted together with eight 0.2 µF ceramic decoupling capacitors on a PC
board.
Each HYB 5117405BJ is described in the data sheet and is fully electrical 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 four presence detect pins.
The common I/O feature on the HYM 324025S/GS-50/-60 dictates the use of early write cycles.
