HYM72V1620/30GS-50/-60

16M x 72-ECC Module

The HYM 72V1600/10GS-50/-60 is a 128 MByte DRAM module organized as 16 777 216 words by

72-bit in a 168-pin, dual read-out, single-in-line package comprising eighteen HYB 3164400AT/AJ

16M

× 4 DRAMs in 400 mil wide TSOPII or SOJ- 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 HYB 3164400AT/AJ

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.

Presence-Detect and ID-pin Truth Table:

Note: 1 = High Level ( Driver Output) , 0 = Low Level (Driver Output) for PDE active ( ground) . For PDE at a high

level all PD terminal are in tri-state.
