Description

TM124FBK32H/ I
The TM124FBK32H/ I is a 4M-byte DRAM organized as four times 1048576 × 8 in a 72-pin SIMM. The SIMM is composed of two TMS418169ADZ 1 048 576 × 16-bit DRAMs, each in a 42-lead plastic SOJ package mounted on a substrate with decoupling capacitors. The TMS418169ADZ is described in the TMS418169A data sheet (literature number SMKS892). The TM124FBK32H/ I SIMM is available in the single-sided BK-leadless module for use with sockets.

TM248GBK32H/ I
The TM248GBK32H/ I is an 8M-byte DRAM organized as four times 2 097 152 × 8 in a 72-pin SIMM. The SIMM is composed of four TMS418169ADZ 1 048 576 × 16-bit DRAMs, each in a 42-lead plastic SOJ package mounted on a substrate with decoupling capacitors. The TMS418169ADZ is described in the TMS418169A data sheet (literature number SMKS892). The TM248GBK32H/ I SIMM is available in the double-sided BK-leadless module for use with sockets.
