description  
The TM2SR72EPU is a 16M-byte, 168-pin dual-in-line memory module (DIMM). The DIMM is composed of nine  
TMS626812DGE, 2097152 x 8-bit SDRAMs, each in a 400-mil, 44-pin plastic thin small-outline package  
(TSOP) mounted on a substrate with decoupling capacitors. See the TMS626812 data sheet (literature number  
SMOS687).  
The TM4SR72EPU is a 32M-byte, 168-pin DIMM. The DIMM is composed of eighteen TMS626812DGE,  
2097152 x 8-bit SDRAMs, each in a 400-mil, 44-pin plastic TSOP mounted on a substrate with decoupling  
capacitors. See the TMS626812 data sheet (literature number SMOS687).  
operation  
The TM2SR72EPU operates as nine TMS626812DGE devices that are connected as shown in the  
TM2SR72EPU functional block diagram. The TM4SR72EPU operates as eighteen TMS626812DGE devices  
connected as shown in the TM4SR72EPU functional block diagram.
