description

TM124BBJ32F

The TM124BBJ32F is a 4-MByte dynamic random-access memory (DRAM) organized as four times 1048576 × 8 in a 72-pin SIMM. The SIMM is composed of two TMS418160DZ, 1048576 × 16-bit DRAMs, each in a 42-lead plastic SOJ package mounted on a substrate with decoupling capacitors. The TMS418160DZ is described in the TMS418160 data sheet. The TM124BBJ32F SIMM is available in the single-sided BJ-leadless module for use with sockets.

TM248CBJ32F

The TM248CBJ32F is an 8-MByte DRAM organized as four times 2097152×8 in a 72-pin SIMM. The SIMM is composed of four TMS418160DZ, 1048576 × 16-bit DRAMs, each in a 42-lead plastic SOJ package mounted on a substrate with decoupling capacitors. The TMS418160DZ is described in the TMS418160 data sheet. The TM248CBJ32F SIMM is available in the double-sided BJ-leadless module for use with sockets.
