description
The TM4TT64KPN is a 32M-byte, 168-pin dual-in-line memory module (DIMM). The DIMM is composed of four TMS664164ADGE, 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 TMS664164A data sheet (literature number SMOS695).
The TM8TT64KPN is a 64M-byte, 168-pin DIMM. The DIMM is composed of eight TMS664164ADGE, 4194304 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).
