description

The TM2SN64EPU is a 16M-byte, 168-pin dual-in-line memory module (DIMM). The DIMM is composed of

eight 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 TM4SN64EPU is a 32M-byte, 168-pin DIMM. The DIMM is composed of sixteen 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 TM2SN64EPU operates as eight TMS626812DGE devices that are connected as shown in the

TM2SN64EPU functional block diagram. The TM4SN64EPU operates as 16 TMS626812DGE devices

connected as shown in the TM4SN64EPU functional block diagram.

Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of

Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.

PRODUCTION DATA information is current as of publication date.

Products conform to specifications per the terms of Texas Instruments

standard warranty. Production processing does not necessarily include

testing of all parameters.
