Industrial Temperature Range

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.
