WED48S8030E
February 2002 Rev. 2
ECO #14194
2M x 8 Bits x 4 Banks Synchronous DR
AM
DESCRIPTION
The WED48S8030E is 67,108,864 bits of synchronous high
data rate DRAM organized as 4 x 2,097,152 words x 8 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 applications.
Available in a 54 pin TSOP type II package the WED48S8030E
is tested over the industrial temp range (-40C to +85C) pro-
viding a solution for rugged main memory applications.
