description
TM124BBK32F
The TM124BBK32F is a 32-megabit dynamic random-access memory (DRAM) organized as four times

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 TM124BBK32F SIMM is available in the single-sided BK-leadless
module for use with sockets.
TM248CBK32F
The TM248CBK32F is a 64-megabit DRAM organized as four times 2 097 152

8 in a 72-pin SIMM. The SIMM
is composed of four 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 TM248CBK32F SIMM is available in the double-sided BK-leadless module for use with sockets.
operation
The TM124BBK32F operates as two TMS418160DZs connected as shown in the functional block diagram and
Table 1. The TM248CBK32F 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.
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.
