DESCRIPTION
Note: Solder Refl ow temperature should not exceed 260°C for 10 seconds
The EDI8L32128V is a high speed, 3.3V, four megabit
density Static RAM. The device is available with access
times of 12, 15 and 20ns, allowing the device to support
60MH
supply voltage and byte confi gurability make the device
ideal for interfacing with Analog Devices ADSP-21062L or
ADSP-21060L SHARC DSPs.
The device can be confi gured as a 128Kx32 and used to
create a single chip external data memory solution for the
SHARC (fi gure 1). Providing a 51% space savings when
compared to four 128Kx8, 400mil wide plastic SOJs. The
EDI8L32128V has a 10pf load on the data lines vs. 24pf for
four plastic SOJs. Memory upgrades in the same footprint
can be accomplished with the EDI8L32256V (256Kx32) or
the EDI8L32512V (512KX32). This is covered in detail in
the application report "The EDI's x32 MCM-L SRAM Family:
Integrated Memory Solution for the Analog SHARC DSP"
Alternatively the device's chip enables can confi gure it as a
256Kx16. A 256Kx48 program memory array for the SHARC
is created using three devices (fi gure 2). If this memory is
too deep, two 128Kx24's (EDI8L24128V) can be used to
create a 128Kx48 memory array.
