EDI8L32512V 512Kx32 SRAM MODULE, 3.3V T NO FEATURES 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. ■ DSP Memory Solution • ADSP-21060L (SHARC) • ADSP-21062L (SHARC) •Texas Instruments TMS320LC31 D DE EN M M CO RE 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 SHARC™ DSP (figure 6). ■ RISC Memory Solution • MPC860 (Power Quic) 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. ■ Random Access Memory Array • Fast Access Times: 12, 15, 17, and 20ns • Individual Byte Enables • User configurable organization with Minimal Additional Logic • Master Output Enable and Write Control • TTL Compatible Inputs and Outputs • Fully Static, No Clocks The device provides a memory upgrade of the EDI8L32256V (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 1Mx 48 program memory array for Analog’s SHARC DSP is created using three devices (figure 7). If 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. ■ Surface Mount Package • 68 Lead PLCC, No. 99 JEDEC M0-47AE • Small Footprint, 0.990 Sq. In. • Multiple Ground Pins for Maximum Noise Immunity Note: Solder Reflow Temperature should not exceed 260°C for 10 seconds. ■ Single +3.3V (±5%) Supply Operation PIN CONFIGURATION R FO FIG. 1 9 8 7 6 5 4 3 2 1 68 67 66 65 64 63 62 61 DQ16 A18 A17 E3 E2 E1 E0 NC VCC NC NC G W A16 A15 A14 DQ15 TOP VIEW DQ14 DQ13 DQ12 V SS DQ11 DQ10 DQ9 DQ8 VCC DQ7 DQ6 DQ5 DQ4 V SS DQ3 DQ2 DQ1 Address Inputs E0-3 Chip Enables (One per Byte) W Master Write Enable G Master Output Enable DQ0-31 Common Data Input/Output VCC Power (+3.3V±5%) VSS Ground NC No Connection BLOCK DIAGRAM DQ31 A6 A5 A4 A3 A2 A1 A0 VCC A13 A12 A11 A10 A9 A8 A7 DQ0 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 A0-18 19 G W E0 E1 E2 E3 NOTE: For memory upgrade information, refer to Page 7, Figure 8 “EDI MCM-L upgrade path.
