EXTERNAL MEMORY SOLUTION FOR TEXAS INSTRUMENTS TMS320C6000 DSP

n Clock speeds:

The EDI9LC644VxxBC is a 3.3V, 128K x 32 Synchronous

Pipeline SRAM and a 1Mx32 Synchronous DRAM array con-

structed with one 128K x 32 SBSRAM and two 1Mx16

SDRAM die mounted on a multilayer laminate substrate. The

device is packaged in a 153 lead, 14mm by 22mm, BGA.

• SSRAM: 200, 166,150, and 133 MHz

• SDRAMs: 125 and 100 MHz

n DSP Memory Solution

• Texas Instruments TMS320C6201

• Texas Instruments TMS320C6701

n Packaging:

The EDI9LC644VxxBC provides a total memory solution for

the Texas Instruments TMS320C6201 and the

TMS320C6701 DSPs

The Synchronous Pipeline SRAM is available with clock

speeds of 200, 166,150, and 133 MHz, allowing the user

to develop a fast external memory for the SSRAM inter-

face port .

• 153 pin BGA, JEDEC MO-163

n 3.3V Operating supply voltage

n Direct control interface to both the SSRAM and SDRAM

ports on the “C6x”

The SDRAM is available in clock speeds of 125 and 100

MHz, allowing the user to develop a fast external memory

for the SDRAM interface port .

n Common address and databus

n 65% space savings vs. monolithic solution

n Reduced system inductance and capacitance
