description
The TM4SP64KPN is a 32M-byte, 168-pin dual-in-line memory module (DIMM). The DIMM is composed of four
TMS664164ADGE, 4 194 304 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 TMS664164A data sheet (literature
number SMOS695).
The TM8SP64KPN is a 64M-byte, 168-pin DIMM. The DIMM is composed of eight TMS664164ADGE,
4 194 304 x 16-bit SDRAMs, each in a 400-mil, 54-pin plastic TSOP mounted on a substrate with decoupling
capacitors. See the TMS664164A data sheet (literature number SMOS695).
operation
The TM4SP64KPN operates as four TMS664164ADGE devices that are connected as shown in the
TM4SP64KPN functional block diagram. The TM8SP64KPN operates as eight TMS664164ADGE devices
connected as shown in the TM8SP64KPN functional block diagram.
