128Kx24 Asynchronous SRAM, 5V
FEATURES
DESCRIPTION
128Kx24 bit CMOS Static
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.
Random Access Memory Array
Fast Access Times: 12 and 15ns
Master Output Enable and Write Control
TTL Compatible Inputs and Outputs
Fully Static, No Clocks
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 BGApackage is 58% less than
a monolithic SOJ solution.
Surface Mount Package
119 Lead BGA (JEDEC MO-163), No. 391
Small Footprint, 14mm x 22mm
Multiple Ground Pins for Maximum Noise
Immunity
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.
Single +5V (±10%) Supply Operation

*Stress greater than those listed under "Absolute Maximum Ratings" may cause
permanent damage to the device. This is a stress rating only and functional operation
of the device at these or any other conditions greater than those indicated in the
operational sections of this specification is not implied. Exposure to absolute maximum
rating conditions for extended periods may affect reliability.
