EXTERNAL MEMORY SOLUTION FOR TEXAS INSTRUMENTS
TMS320C6000 DSP
DESCRIPTION
FEATURES
The WED9LC6816V is a 3.3V, 256K x 32 Synchronous
Clock speeds:
SSRAM: 200, 166,150, and 133 MHz
SDRAMs: 125 and 100 MHz
Pipeline SRAM and a 4Mx32 Synchronous DRAM array
constructed with one 256K x 32 SBSRAM and two 4Mx16
SDRAM die mounted on a multilayer laminate substrate.
The device is packaged in a 153 lead, 14mm x 22mm,
DSP Memory Solution
BGA.
Texas Instruments TMS320C6201
Texas Instruments TMS320C6701
Packaging:
The WED9LC6816V 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,v and 133
153 pin BGA, JEDEC MO 163
3.3V Operating supply voltage
Direct control interface to both the SSRAM and
SDRAM ports on the “C6x”
Common address and databus
65% space savings vs. monolithic solution
MHz, allowing the user to develop a fast external memory
for the SSRAM interface port .
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.
The WED9LC6816V is available in both commercial and
industrial temperature ranges.
Reduced system inductance and capacitance
