White Electronic Designs EDI8L32512C 512Kx32 CMOS High Speed Static RAM FEATURES DESCRIPTION The EDI8L32512C is a high speed, 5V, 16Mb SRAM. The device is available with access times of 12, 15, 17 and 20ns allowing the creation of a no wait state DSP memory solution. The high speed, 5v supply voltage and control lines make the divice ideal for creating floating point DSP memory solutions. DSP Memory Solution Motorola DSP96002 Analog SHARC DSP Texas Instruments TMS320C3x, TMS320C4x Random Access Memory Array Fast Access Times: 12*, 15, 17, and 20ns TTL Compatible I/O Fully Static, No Clocks The device can be configured as a 512K x 32 and used to create a single chip external data memory solution for TI's TMS320C30/C31 (Figure 8), TMS320C32 (Figure 9) or TMS320C4x (Figure 10), Motorola's DSP96002 and Analog's SHARC DSP (Figure 11). Alternatively, the device's chip enables can be used to configure it as a 1M x 16. A 1M x 48 program memory array for Analog's SHARC DSP is created using three devices (Figure 12). If this memory is too deep, two 512K x 24s (EDI8L24512C) can be used to create a 512K x 48 array or two 128K x 48 array. Surface Mount Package 68 Lead PLCC, No. 99 JEDEC M0-47AE Small Footprint, 0.990 Sq. In. Multiple Ground Pins for Maximum Noise Immunity Single +5V (±5%) Supply Operation The device provides a 56% space savings when compared to four 512K x 8, 36 pin SOJs. In addition the EDI8L32512C has only a 10pF load on the data lines vs. 32pF for four plastic SOJs. * Advanced Information The device provides a memory upgrade of the EDI8L32256C (256K x 32) or the EDI8L32128C (128K x 32). For additional upgrade information see Figure 13. Note: Solder Reflow Temperature should not exceed 230°C for 10 seconds.
