Pin Configurations and Block Diagram
256Kx32, 5V Static Ram
The EDI8L32256C is a high speed, 5V, 8 megabit SRAM.
The device is available with access times of 15, 17, 20 and
25ns, allowing the creation of a no wait state DSP memory
solution.
The device can be configured as a 256Kx32 and used to
create a single chip external data memory solution for
Texas Instruments' TMS320C30/31, TMS 320C32 or
TMS320C4x, Motorola's DSP96002 and Analog Device's
SHARCTM DSP.
Alternatively the device's chip enables can be used to
configure it as a 512Kx16. A 512Kx48 program memory
array for Analog's SHARCTM DSP is created using three
devices. If this memory is too deep, two 256Kx24s
(EDI8L24256C) can be used to create a 256Kx48 array or
two 128Kx24s (EDI8L24128C) can be used to create a
128Kx48 array.
The device provides a 32% space savings when compared
to two monolithic 256Kx16, 44 pin SOJs.
The device provides a memory upgrade of the
EDI8L32128C (128Kx32) and the EDI8L3265C (64Kx32).
For more memory the device can be upgraded to the
EDI8L32512C (512Kx32).
NOTE: Solder Reflow temperature should not exceed 260°C for 10 seconds.
