description
The TM2SN64EPH is a 16M-byte, 168-pin dual-in-line memory module (DIMM). The DIMM is composed of
eight TMS626812BDGE, 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 TMS626812B data sheet (literature
number SMOS693).
The TM4SN64EPH 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 TM2SN64EPH operates as eight TMS626812BDGE devices that are connected as shown in the
TM2SN64EPH functional block diagram. The TM4SN64EPH operates as sixteen TMS626812BDGE devices
connected as shown in the TM4SN64EPH functional block diagram.
