HYM321005S Datasheet, PDF (2/10 Pages) Siemens Semiconductor Group – 1M x 32-Bit Dynamic RAM Module

HYM 321005S/GS-50/-60
1M × 32-Bit EDO-Module
The HYM 321005S/GS-50/-60 is a 4 MByte EDO- DRAM module organized as 1 048 576 words by
32-bit in a 72-pin single-in-line package comprising two HYB 5118165BSJ 1M × 16 EDO-DRAMs
in 400 mil wide SOJ-packages mounted together with two 0.2 µF ceramic decoupling capacitors on
a PC board.
Each HYB 5118165BSJ 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 speed of the module can be detected by the use of presence detect pins.
The common I/O feature on the HYM 321005S/GS-50/-60 dictates the use of early write cycles.
