128Kx32 CMOS High Speed Static RAM

FEATURES

DESCRIPTION

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_ZDSPs with no wait states. The high speed, 3.3V

supply voltage and byte conﬁgurability make the device

ideal for interfacing with Analog Devices ADSP-21062L or

ADSP-21060L SHARC DSPs.

with Minimal Additional Logic

The device can be conﬁgured as a 128Kx32 and used to

create a single chip external data memory solution for the

SHARC (ﬁgure 1). Providing a 51ꢀ 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"

Noise Immunity

Alternatively the device's chip enables can conﬁgure it as a

256Kx16. A256Kx48 program memory array for the SHARC

is created using three devices (ﬁgure 2). If this memory is

too deep, two 128Kx24's (EDI8L24128V) can be used to

create a 128Kx48 memory array.
