The DIMM is composed of eight TMS626812ADGE, 2 097 152 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 TMS626812A data sheet (literature number SMOS691). The TM4SN64EPN is a 32M-byte, 168-pin DIMM. The DIMM is composed of sixteen TMS626812ADGE, 2 097 152 x 8-bit SDRAMs, each in a 400-mil, 44-pin plastic TSOP mounted on a substrate with decoupling capacitors. See the TMS626812A data sheet (literature number SMOS691). operation The TM2SN64EPN operates as eight TMS626812ADGE devices that are connected as shown in the TM2SN64EPN functional block diagram. The TM4SN64EPN operates as sixteen TMS626812ADGE devices connected as shown in the TM4SN64EPN functional block diagram.
