DESCRIPTION
The WED416S16030A is 268,435,456 bits of synchronous
high data rate DRAM organized as 4 x 4,196,304 words x
16 bits. Synchronous design allows precise cycle control
with the use of system clock. I/O transactions are possible
on every clock cycle. Range of operating frequencies,
programmable burst lengths and programmable latencies
allow the same device to be useful for a variety of high
bandwidth, high performance memory system applica-
tions.
Available in a 54 pin TSOP type II package the
WED416S16030A is tested over the industrial temp range
(-40°C to +85°C) providing a solution for rugged main
memory applications.
