DESCRIPTION
The EDI8L24129VxxBC is a 3.3V, three megabit SRAM
constructed with three 128Kx8 die mounted on a multi-
layer laminate substrate. With 10 to 15ns access times,
x24 width and a 3.3V operating voltage, the EDI8L24129V
is ideal for creating a single chip memory solution for the
Motorola DSP5630x (Figure 3) or a two chip solution for
the Analog Devices SHARCTM DSP (Figure 4).
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. For example, the capacitance
load on the data lines for the BGA package is 58% less
than a monolithic SOJ solution.
The JEDEC Standard 119 lead BGA provides a 44% space
savings over using 128Kx8, 300mil wide SOJs and the BGA
package has a maximum height of 100 mils compared to
148 mils for the SOJ packages. The BGA package also
allows the use of the same manufacturing and inspection
techniques as the Motorola DSP, which is also in a BGA
package.
