HYM368025S Datasheet, PDF (2/10 Pages) Siemens Semiconductor Group – 8M x 36-Bit EDO - DRAM Module

HYM 368025S/GS-50/-60
8M × 36-Bit EDO-Module
The HYM 368025S/GS-50/-60 is a 32 MByte DRAM module organized as 8 388 608 words by 36-
Bit in two banks in a 72-pin single-in-line package comprising sixteen HYB 5117405BJ 4M × 4
EDO-DRAMs and eight HYB 514105BJ 4M x 1 EDO-DRAMs in 300 mil wide SOJ-packages
mounted together with decoupling capacitors on a PC board.
Each HYB 5117405BJ and HYB 514105BJ 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 368025S/GS-50/-60 dictates the use of early write cycles.
