description

The TMS41x809 series is a set of high-speed,

16 777 216-bit dynamic random-access memo-

ries (DRAMs) organized as 2 097 152 words of

eight bits each. It employs TI’s state-of-the-art

EPIC technology for high performance, reliability,

and low power.

These devices feature maximum RAS access

times of 60 ns, 70 ns, and 80 ns. All addresses and

data-in lines are latched on chip to simplify system

design. Data out is unlatched to allow greater

system flexibility.

The TMS41x809 is offered in a 28-lead plastic

surface-mount SOJ package (DZ suffix). This

package is characterized for operation from 0

°C

to 70

°C.

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.
