DESCRIPTION
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 fl oating point DSP memory
solutions.
The device can be confi gured 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 and Analog's
SHARC DSP (Figure 11). Alternatively, the device's chip
enables can be used to confi gure 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.
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.
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 Refl ow Temperature should not exceed 230°C for 10 seconds.
