description

TM124FBK32F

The TM124FBK32F is a 4M-byte DRAM organized as four times 1048576 × 8 in a 72-pin SIMM. The SIMM is composed of two TMS418169DZ 1048576 × 16-bit DRAMs, each in a 42-lead plastic SOJ package mounted on a substrate with decoupling capacitors. The TMS418169DZ is described in the TMS418169 data sheet (literature number SMKS886). The TM124FBK32F SIMM is available in the single-sided BK-leadless module for use with sockets.

TM248GBK32F

The TM248GBK32F is an 8M-byte DRAM organized as four times 2097152×8 in a 72-pin SIMM. The SIMM is composed of four TMS418169DZ 1048576 × 16-bit DRAMs, each in a 42-lead plastic SOJ package mounted on a substrate with decoupling capacitors. The TMS418169DZ is described in the TMS418169 data sheet (literature number SMKS886). The TM248GBK32F SIMM is available in the double-sided BK-leadless module for use with sockets.
