| White Electronic Designs 128Kx32 CMOS High Speed Static RAM FEATURES 128Kx32 bit CMOS Static Analog SHARC TM EDI8L32128V DESCRIPTION External Memory Solution 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 60MHZ DSPs 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. 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 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 configure it as a 256Kx16. A 256Kx48 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. Note: Solder Reflow temperature should not exceed 260C for 10 seconds ADSP-21060L ADSP-21062L Random Access Memory Array Fast Access Times: 12, 15 and 20ns User Configurable Organization with Minimal Additional Logic Master Output Enable and Write Control TTL Compatible Inputs and Outputs Fully Static, No Clocks Surface Mount Package 68 Lead PLCC, No. 99 (JEDEC MO-47AE) Small Footprint, 0.990 Sq.
