description
The TM8TU72JPW is a 64M-byte, 168-pin registered dual-in-line memory module (DIMM). The registered
DIMM is composed of nine TMS664814DGE, 8 388 608 x 8-bit SDRAMs, each in a 400-mil, 54-pin plastic thin
small-outline package (TSOP); two SN74ALVC162836DGG, 20-bit universal bus drivers, each in a 240-mil,
56-pin thin shrink small-outline package (TSSOP); and one CDC2510 phase-lock loop (PLL) in a 177-mil, 24-pin
TSSOP mounted on a substrate with decoupling capacitors. See the TMS664814 data sheet (literature number
SMOS695), the SN74ALVC162836 data sheet (literature number SCES129), and the CDC2510 data sheet
(literature number SCAS597) for reference.
operation
The TM8TU72JPW operates as nine TMS664814DGE devices that are connected as shown in the
TM8TU72JPW functional block diagram.
