description
The TM2CN64EFH is a 16M-byte, 168-pin dual-in-line memory module (DIMM). The DIMM is composed of eight TMS626812BDGE 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 TMS626812B data sheet (literature number SMOS693). The TM4CN64EFH is a 32M-byte, 168-pin DIMM. The DIMM is composed of sixteen TMS626812BDGE 2 097 152 x 8-bit SDRAMs, each in a 400-mil, 44-pin plastic TSOP mounted on a substrate with decoupling capacitors.
operation
The TM2CN64EFH operates as eight TMS626812BDGE devices that are connected as shown in the TM2CN64EFH functional block diagram. The TM4CN64EFH operates as sixteen TMS626812BDGE devices connected as shown in the TM4CN64EFH functional block diagram.
