† 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.
NOTE 1: All voltage values are with respect to VSS.DescriptionThe TM8EN64NPU is a 32M-byte, 168-pin, dual-in-line memory module (DIMM). The DIMM is composed of four TMS465169, 4194304 × 16-bit 4K-refresh EDO dynamic random-access memory (DRAM) devices, each in a 400-mil, 50-pin plastic thin small-outline package (TSOP) (DGE suffix) mounted on a substrate with decoupling apacitors. See the TMS465169 data sheet (literature number SMHS566).
