• Manufacturer Part Number: IDT72T6480
• Description: X48 Sequential Flow-control Device Up To 1gigabit
• Manufacturer: Integrated Device Technology

DESCRIPTION
a seamless connection to external DDR SDRAM for significant storage
capacity supporting high-speed applications. Both read and write ports of the
sequential flow-control can operate independently at up to 133MHz. There
is a user selectable correction feature that will correct any erroneous single
data bit when reading from the SDRAM.
clocks, enables, and chip selects. Both ports can operate either synchro-
nously or asynchronously. Other features include bus-matching, program-
mable status flags with selectable synchronous/asynchronous timing modes,
IDT Standard or FWFT mode timing, and JTAG boundary scan functionality.

128Mb or 256Mb. The device will support industry standard DDR specification
memories (note DDR II is not supported), which include vendors such as
Samsung, Micron, and Infineon. The data bus connected to the DDR SDRAM
can be 16-bit, 32-bit, or 64-bits wide. The sequential flow-control device can
independently control up to four separate external memories for a maximum of
density of 1Gb (128MB). Depth expansion mode is available for applications
that require more than 1Gb of storage memory.
The device package is 19mm x 19mm 324-pin PBGA. It operates at a 2.5V
