WED3DL3216V
DESCRIPTION
The WED3DL3216V is an 16Mx32 Synchronous DRAM
configured as 4x4Mx32. The SDRAM BGA is constructed
with two 16Mx16 SDRAM die mounted on a multi-layer
laminate substrate and packaged in a 119 lead, 17mm
by 23mm, BGA.
The WED3DL3216V is available in clock speeds of
133MHz, 125MHz, and 100MHz. The range of operat-
ing frequencies, programmable burst lengths and pro-
grammable latencies allow the same device to be use-
ful for a variety of high bandwidth, high performance
memory system applications.
The package and design provides performance en-
hancements via a 50% reduction in capacitance vs.
two monolithic devices. The design includes internal
ground and power planes which reduces inductance
on the ground and power pins allowing for improved
decoupling and a reduction in system noise.
