description
The TM4SK64KPN is a 32M-byte, 144-pin small-outline dual-in-line memory module (SODIMM). The SODIMM is composed of four TMS664164DGE, 4194304 x 16-bit SDRAMs, each in a 400-mil, 54-pin plastic thin small-outline package (TSOP) mounted on a substrate with decoupling capacitors. See the TMS664164 data sheet (literature number SMOS695). The TM8SK64KPN is a 64M-byte, 144-pin SODIMM. The SODIMM is composed of eight TMS664164DGE, 4194304 x 16-bit SDRAMs, each in a 400-mil, 54-pin plastic TSOP mounted on a substrate with decoupling capacitors. See the TMS664164 data sheet (literature number SMOS695). operation The TM4SK64KPN operates as four TMS664164DGE devices that are connected as shown in the TM4SK64KPN functional block diagram. The TM8SK64KPN operates as eight TMS664164DGE devices connected as shown in the TM8SK64KPN functional block diagram.

NOTES: 11. tAC is referenced from the rising transition of CK that precedes the data-out cycle. For example, the first data out tAC is referenced from the rising transition of CK that is read latency (one cycle after the READ command). Access time is measured at output reference level 1.4 V. 12. tLZ is measured from the rising transition of CK that is read latency (one cycle after the READ command). 13. tHZ (max) defines the time at which the outputs are no longer driven and is not referenced to output voltage levels. 14. For read or write operations with automatic deactivate, tRCD must be set to satisfy minimum tRAS . PRODUCT PREVIEW
