DESCRIPTION
The EDI416S4030A is 67,108,864 bits of synchronous high
data rate DRAM organized as 4 x 1,048,576 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 applications.
Available in a 54 pin TSOP type II package the
EDI416S4030A is tested over the industrial temp range (-
40C to +85C) providing a solution for rugged main memory
applications.
