WED8L24513V
DESCRIPTION
The WED8L24513VxxBC is a 3.3V, twelve megabit SRAM
constructed 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 WED8L24513V is ideal
for creating a single chip memory solution for the Motorola
DSP5630x (Figure 7) or a two chip solution for the Analog
Devices SHARC
TM
DSP (Figure 8).
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.
