description
The TMS41x800 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 TMS416800 and TMS417800 are offered in
a 28-lead plastic surface-mount SOJ package
(DZ suffix). This package is characterized for
operation from 0°C to 70°C.
