DESCRIPTION
The WED9LC6416VxxBC is a 3.3V, 128K x 32 Synchronous
Pipeline SRAM and a 4M x 32 Synchronous DRAM array
constructed with one 128K x 32 SSRAM and two 4M x 16
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 Instr uments TMS320C6201 and the
TMS320C6701 DSPs.
The Synchronous Pipeline SSRAM 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 por t.
The WED9LC6416V is available in both commercial and in-
dustrial temperature ranges.
