HYM 328020S/GS-50/-60

8M

× 32-Bit

The HYM 328020S/GS-50/-60 is a 32 MByte DRAM module organized as 8 388 608 words by

32-bit in a 72-pin single-in-line package comprising sixteen HYB 5117400BJ 4M

× 4 DRAMs in 300

mil wide SOJ-packages mounted together with sixteen 0.2

µF ceramic decoupling capacitors on a

PC board.

The HYM 328020S/GS-50/-60 can also be used as a 16 777 360 words by 16-bits dynamic RAM

module by means of connecting DQ0 and DQ16, DQ1 and DQ17, DQ2 and DQ18, … , DQ15 and

DQ31, respectively.

Each HYB 5117400BJ 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 328020S/GS-50/-60 dictates the use of early write cycles.
