HYM 322160S/GS-60/-70
2M x 32-Bit
The HYM322160S/GS-60/-70 is a 8 MByte DRAM module organized as 2 097 152 words by
32-Bit in a 72-pin single-in-line package comprising sixteen HYB514400BJ 1M × 4 DRAMs in 300
mil wide SOJ-packages mounted together with eight 0.2 µF ceramic decoupling capacitors on a PC
board.
The HYM322160S/GS-60/-70 can also be used as a 4 194 304 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 HYB514400BJ 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 322160S/GS-60/-70 dictates the use of early write cycles.

Notes:
1) All voltages are referenced to VSS .
2) ICC1, ICC3, ICC4 and ICC6 depend on cycle rate.
3) ICC1 and ICC4 depend on output loading. Specified values are measured with the output open.
4) An initial pause of 200 µs is required after power-up followed by 8 RAS cycles out of which at least one cycle
has to be a refresh cycle before proper device operation is achieved. In case of using internal refresh counter,
a minimum of 8 CAS-before-RAS initialization cycles instead of 8 RAS cycles are required.
5) VIH (min.) and VIL (max.) are reference levels for measuring timing of input signals. Transition times are also
measured between VIH and VIL .
6) Measured with a load equivalant of 2 TTL loads and 100 pF.
7) tOFF (max.) defines the time at which the output achieves the open-circuit condition and is not referenced to
output voltage levels.
8) Either tRCH or tRRH must be satisfied for a read cycle.
9) These parameters are referenced to the CAS leading edge.
10) tWCS is not a restrictive operating parameter. This is included in the data sheet as electrical characteristic only.
If tWCS > tWCS (min.), the cycle is an early write cycle and data out pin will remain open circuit (high impedance).
11) Operation within the tRCD (max.) limit insures that tRAC (max.) can be met. tRCD (max.) is specified as a reference
point only. If tRCD is greater than the specified tRCD (max.) limit, then access time is controlled by tCAC .
12) Operation within the tRAD (max.) limit insures that tRAC (max.) can be met. tRAD (max.) is specified as a reference
point only. If tRAD is greater than the specified tRAD (max.) limit, then access time is controlled by tAA .
13)For CAS-before-RAS cycles only.
