| White Electronic Designs 512Kx32 SRAM Module.3.3V FEATURES DSP Memory Solution ADSP-21060L (SHARC) ADSP-21062L (SHARC) Texas Instruments TMS320LC31 MPC860 (Power Quic) Fast Access Times: 12, 15, 17, and 20ns Individual Byte Enables User configuration organization with Minimal Additional Logic Master Output Enable and Write Control TTL Compatible Inputs and Outputs Fully Static, No Clocks 68 Lead PLCC, No. 99 JEDEC MO-47AE Small Footprint, 0.990 Sq. In. Multiple Ground Pins for Maximum Noise Immunity EDI8L32512V DESCRIPTION The EDI8L32512V is a high speed, 3.3V, 16 megabit SRAM. The device is available with access times of 12, 15, 17 and 20ns allowing the creation of a no wait state DSP and RISC microprocessor memory solutions. The device can be configured as a 512K x 32 and used to create a single chip external data memory solution for TI's TMS320LC31 (figure 5), or Analog's SHARCTM DSP (figure 6). The device provides a 56% space savings when compared to four 512Kx8, 36 pin SOJs. In addition the EDI8K32512V has only a 10pF load on the data lines vs. 32 pF for four plastic SOJs. The device provides a memory upgrade of the EDI8F32256V (256K x 32) or the EDI8L32128V (128K x 32) (figure 8). Alternatively, the device's chip enables can configure it as a 1M x 16. A 1M x 48 program memory array for Analog's CHARC DSP is created using three devices (figure 7). If RISC Memory Solution Random Access Memory Array Surface Mount Package this memory is too deep, two 512K x 24s (EDI8L24512V) can be used to create a 512K x 48 array or two 128K x 24s (EDI8L24128V) can be used to create a 128K x 48 array. Note: Soldier Reflow Temperature should not exceed 260C for 10 seconds.
