description
The TM16EN64HPU is a 128M-byte, 168-pin, dual-in-line memory module (DIMM). The DIMM is composed
of sixteen TMS465409, 16 777 216
× 4-bit 4K-refresh EDO dynamic random-access memories (DRAMs), each
in a 400-mil, 32-pin plastic thin small-outline package (TSOP) (DGC suffix) mounted on a substrate with
decoupling capacitors. See the TMS465409 data sheet (literature number SMKS895).
The TM16EN64LPU is a 128M-byte, 168-pin DIMM. The DIMM is composed of eighteen TMS464409,
16 777 216
× 4-bit 8K-refresh EDO dynamic random-access memories (DRAMs), each in a 400-mil, 32-pin
plastic TSOP (DGC suffix) mounted on a substrate with decoupling capacitors. See the TMS465409 data sheet
(literature number SMKS895).
The TM16EN72HPU is a 128M-byte, 168-pin DIMM. The DIMM is composed of eighteen TMS465409,
16 777 216
× 4-bit 4K-refresh EDO dynamic random-access memories (DRAMs), each in a 400-mil, 32-pin
plastic TSOP (DGC suffix) mounted on a substrate with decoupling capacitors. See the TMS465409 data sheet
(literature number SMKS895).
The TM16EN72LPU is a 128M-byte, 168-pin DIMM. The DIMM is composed of eighteen TMS464409, 4194 309
× 4-bit 8K-refresh EDO dynamic random-access memories (DRAMs), each in a 400-mil, 32-pin plastic TSOP
(DGC suffix) mounted on a substrate with decoupling capacitors. See the TMS465409 data sheet (literature
number SMKS895).
operation
The TM16EN64xPU operates as sixteen TMS46x409s that are connected as shown in the TM16EN64xPU
functional block diagram. The TM16EN72xPU operates as eighteen TMS46x409s that are connected as shown
in the TM16EN72xPU functional block diagram.
