description
The TM8TT64JPN is a 64M-byte, 168-pin dual-in-line memory module (DIMM). The DIMM is composed of eight
TMS664814ADGE, 8 388 608 x 8-bit SDRAMs, each in a 400-mil, 54-pin plastic thin small-outline package
(TSOP) mounted on a substrate with decoupling capacitors. See the TMS664814 data sheet (literature number
SMOS695).
The TM16TT64JPN is a 128M-byte, 168-pin DIMM. The DIMM is composed of sixteen TMS664814ADGE,
8 388 608 x 8-bit SDRAMs, each in a 400-mil, 54-pin plastic TSOP mounted on a substrate with decoupling
capacitors. See the TMS664814 data sheet (literature number SMOS695).
The TM8TT72JPN is a 64M-byte, 168-pin DIMM. The DIMM is composed of nine TMS664814ADGE,
8 388 608 x 8-bit SDRAMs, each in a 400-mil, 54-pin plastic thin small-outline package (TSOP) mounted on a
substrate with decoupling capacitors. See the TMS664814 data sheet (literature number SMOS695).
The TM16TT72JPN is a 128M-byte, 168-pin DIMM. The DIMM is composed of eighteen TMS664814ADGE,
2 097 152 x 8-bit SDRAMs, each in a 400-mil, 54-pin plastic TSOP mounted on a substrate with decoupling
capacitors. See the TMS664814 data sheet (literature number SMOS695).
