description

TM124BBK32H/I

The TM124BBK32H/I is a 32M-bit dynamic random-access memory (DRAM) module organized as four times

1048576 × 8 in a 72-pin SIMM. The SIMM is composed of two TMS418160ADZ, 1 048 576 × 16-bit DRAMs,

each in a 42-lead plastic SOJ package mounted on a substrate with decoupling capacitors. The

TMS418160ADZ is described in the TMS418160A data sheet (literature number SMKS891). The

TM124BBK32H/I SIMM is available in the single-sided BK-leadless module for use with sockets.

TM248CBK32H/I

The TM248CBK32H/I is a 64M-bit DRAM organized as four times 2 097 152 × 8 in a 72-pin SIMM. The SIMM

is composed of four TMS418160ADZ, 1048576 × 16-bit DRAMs, each in a 42-lead plastic SOJ package

mountedonasubstratewithdecouplingcapacitors. TheTMS418160ADZisdescribedintheTMS418160Adata

sheet (literature number SMKS891). The TM248CBK32H/I SIMM is available in the double-sided BK-leadless

module for use with sockets.

operation

The TM124BBK32H/I operates as two TMS418160ADZ DRAMs, connected as shown in the functional block

diagram and Table 1. The TM248CBK32H/I operates as four TMS418160ADZ DRAMs connected as shown

in the functional block diagram and Table 1. The common I/O feature dictates the use of early-write cycles to

prevent contention on D and Q.

Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of

Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.

Part numbers in this data sheet are for the gold-tabbed version; the information applies to both gold-tabbed and solder-tabbed versions.

PRODUCTION DATA information is current as of publication date.

Products conform to specifications per the terms of Texas Instruments

standard warranty. Production processing does not necessarily include

testing of all parameters.
