CMOS SyncBiFIFOTM 256 x 18 x 2 512 x 18 x 2
IDT72605 IDT72615
FEATURES:
• Two independent FIFO memories for fully bidirectional data transfers
• 256 x 18 x 2 organization (IDT72605)
• 512 x 18 x 2 organization (IDT72615)
• Synchronous interface for fast (20ns) read and write cycle times
• Each data port has an independent clock and read/write control
• Output enable is provided on each port as a three-state control of the data bus
• Built-in bypass path for direct data transfer between two ports
• Two fixed flags, Empty and Full, for both the A-to-B and the Bto-A FIFO
• Programmable flag offset can be set to any depth in the FIFO
• The synchronous BiFIFO is packaged in a 64-pin TQFP (Thin Quad Flatpack) and 68-pin PLCC
• Industrial temperature range (–40°C to +85°C) • Green parts available, see ordering information
DESCRIPTION:
The IDT72605 and IDT72615 are very high-speed, low-power bidirectional First-In, First-Out (FIFO) memories, with synchronous inte.
