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  
DSP Memory Solution  
Motorola DSP5600x™  
Analog Devices SHARC™
