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, 1 048 576 × 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 2 097 152 × 8 in a 72-pin SIMM. The SIMM

is composed of four TMS418160DZ, 1048576 × 16-bitDRAMs, eachina42-leadplasticSOJpackagemounted

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.

operation

The TM124BBJ32F operates as two TMS418160DZs connected as shown in the functional block diagram and

Table 1. The TM248CBJ32F operates as four TMS418160DZs 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.
