FEATURES

DESCRIPTION

ꢀ

128Kx24 bit CMOS Static

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).

ꢀ

Random Access Memory Array

• Fast Access Times: 10, 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 BGA package is 58ꢀ 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 BGAprovides a 44ꢀ 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.
