IDT72V243 General Description
•The IDT72V223/72V233/72V243/72V253/72V263/72V273/72V283/ 72V293 are exceptionally deep, high speed, CMOS First-In-First-Out (FIFO) memories with clocked read and write controls and a flexible Bus-Matching x9/ x18 data flow. These FIFOs offer numerous improvements over previous SuperSync FIFOs, including the following: Flexible x9/x18 Bus-Matching on both read and write ports The limitation of the frequency of one clock input with respect to the other has been removed. The Frequency Select pin (FS) has been removed, thus it is no longer necessary to select which of the two clock inputs, RCLK or WCLK, is running at the higher frequency.
• The period required by the retransmit operation is now fixed and short.
• The first word data latency period, from the time the first word is written to an empty FIFO to the time it can be read, is now fixed and short. (The variable clock cycle counting delay associated with the latency period found on previous SuperSync devices has been eliminated on this SuperSync family.)
• Asynchronous/Synchronous translation on the read or write ports
• High density offerings up to 1 Mbit
Bus-Matching SuperSync FIFOs are particularly appropriate for network, video, telecommunications, data communications and other applications that need to buffer large amounts of data and match busses of unequal sizes.
