DESCRIPTION
The EDI8L24128CxxBC is a 5V, three megabit SRAM
constructed with three 128Kx8 die mounted on a multi-
layer laminate substrate. With 12 to 15ns access times, x24
width and a 5V operating voltage, the EDI8L2418C is ideal
for creating a single chip memory solution for the Motorola
DSP5600x or a two chip solution for the Analog Devices
SHARC™ 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. 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, 300mm wide SOJs and the
BGA package has a height of 100mm compared to 148mm
for the SOJ packages.
