† Stresses beyond those listed under "absolute maximum ratings" may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under "recommended operating conditions" is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.

The TM2EJ64DPN is a 16M-byte, 144-pin, small outline dual-in-line memory module (SODIMM). The SODIMM is composed of eight TMS427809A, 2097152 × 8-bit 2K-refresh EDO dynamic random-access memories (DRAMs), each in a 400-mil, 28-pin plastic thin small-outline package (TSOP) (DGC suffix) mounted on a substrate with decoupling capacitors. See the TMS427809A data sheet (literature number SMKS894).

The TM2EJ64EPN is an 16M-byte, 144-pin SODIMM. The SODIMM is composed of eight TMS426809A, 2097152 × 8-bit 4K-refresh EDO DRAMs, each in a 400-mil, 28-pin plastic TSOP (DGC suffix) mounted on a substrate with decoupling capacitors. See the TMS426809A data sheet (literature number SMKS894). The TM2FJ64DPN is a 16M-byte, 144-pin SODIMM. The SODIMM is composed of eight TMS427809AP, 2097152 × 8-bit 2K low-power battery-backup refresh EDO DRAMs, each in a 400-mil, 28-pin plastic TSOP (DGC suffix) mounted on a substrate with decoupling capacitors.
