The EDI8L32512V is a high speed, 3.3V, 16 megabit SRAM.
The device is available with access times of 12, 15, 17 and
20ns allowing the creation of a no wait state DSP and RISC
microprocessor memory solutions.
The device can be configured as a 512K x 32 and used to
create a single chip external data memory solution for TI's
TMS320LC31 (figure 5), or Analog's SHARCTM DSP (figure
6).
RISC Memory Solution


DESCRIPTION
DSP Memory Solution
MPC860 (Power Quic)
Random Access Memory Array

Fast Access Times: 12, 15, 17, and 20ns

Individual Byte Enables

User configuration organization with Minimal
Additional Logic

Master Output Enable and Write Control

TTL Compatible Inputs and Outputs

Fully Static, No Clocks
The device provides a 56% space savings when compared
to four 512Kx8, 36 pin SOJs. In addition the EDI8K32512V
has only a 10pF load on the data lines vs. 32 pF for four
plastic SOJs.
The device provides a memory upgrade of the EDI8F32256V
(256K x 32) or the EDI8L32128V (128K x 32) (figure 8).
Alternatively, the device's chip enables can configure it as
a 1M x 16. A 1M x 48 program memory array for Analog's
CHARC DSP is created using three devices (figure 7). If

this memory is too deep, two 512K x 24s (EDI8L24512V)
can be used to create a 512K x 48 array or two 128K x
24s (EDI8L24128V) can be used to create a 128K x 48
array.
