DESCRIPTION
The WED8L24514VxxBC is a 3.3V, twelve megabit SRAM con-
structed with three 512Kx8 die mounted on a multi-layer laminate
substrate. With 10 to 15ns access times, x24 width and a 3.3V
operating voltage, the WED8L24514V is ideal for creating a single chip
memory solution for the Motorola DSP5630x or a two chip solution
for the Analog Devices SHARCTM DSP.
The single or dual chip memory solutions offer improved system
performance by reducing the length of board traces and the number
of board connections compared to using multiple monolithic devices.
The JEDEC Standard 119 lead BGA provides a 61% space savings
over using three 512Kx8, 400 mil wide SOJs and the BGA package
has a maximum height of 110 mils compared to 148 mils for the SOJ
packages.
