DSP Memory Solution
The EDI8L32512C is a high speed, 5V, 16Mb SRAM. The
device is available with access times of 12, 15, 17 and
20ns allowing the creation of a no wait state DSP memory
solution. The high speed, 5v supply voltage and control lines
make the divice ideal for creating floating point DSP memory
solutions.

Motorola DSP96002
Analog SHARC DSP
Texas Instruments TMS320C3x, TMS320C4x
Random Access Memory Array
The device can be configured as a 512K x 32 and used to
create a single chip external data memory solution for TI's
TMS320C30/C31 (Figure 8), TMS320C32 (Figure 9) or
TMS320C4x (Figure 10), Motorola's DSP96002 andAnalog's
SHARC DSP (Figure 11). Alternatively, the device's chip
enables can be used to configure it as a 1M x 16. A 1M x 48
program memory array for Analog's SHARC DSP is created
using three devices (Figure 12). If this memory is too deep,
two 512K x 24s (EDI8L24512C) can be used to create a 512K
x 48 array or two 128K x 48 array.

68 Lead PLCC, No. 99 JEDEC M0-47AE
Small Footprint, 0.990 Sq. In.
Multiple Ground Pins for Maximum Noise Immunity
Single +5V ( 5ꢀ% Supply Operation
The device provides a 56% space savings when compared
to four 512K x 8, 36 pin SOJs. In addition the EDI8L32512C
has only a 10pF load on the data lines vs. 32pF for four
plastic SOJs.
* Advanced Information
The device provides a memory upgrade of the EDI8L32256C
(256K x 32) or the EDI8L32128C (128K x 32). For additional
upgrade information see Figure 13.
Note: Solder Reflow Temperature should not exceed 230°C for 10 seconds.

*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.
