DESCRIPTION
The WED9LC6416VxxBC is a 3.3V, 128K x 32 Synchronous
Pipeline SRAM and a 4Mx32 Synchronous DRAM array con-
structed with one 128K x 32 SBSRAM and two 4Mx16 SDRAM die
mounted on a multilayer laminate substrate. The device is
packaged in a 153 lead, 14mm by 22mm, BGA.
The WED9LC6416VxxBC 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 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 WED9LC6416V is available in both commercial and industrial
temperature ranges.
