The IDT7203/7204/7205/7206/7207/7208 are dual-port memory buffers with internal pointers that load and empty data on a first-in/first-out basis. The device uses Full and Empty flags to prevent data overflow and underflow and expansion l ogic t o a llow f or u nlimited e xpansion c apability i n b oth w ord s ize a nd depth.
Data is toggled in and out of the device through the use of the Write (W ) and Read (R ) pins.
The device's 9-bit width provides a bit for a control or parity at the user’s option. It also features a Retransmit (RT ) capability that allows the read pointer to be reset to its initial position when RT is pulsed LOW. A Half-Full Flag is available in the single device and width expansion modes.
These FIFOs are fabricated using IDT’s high-speed CMOS technology.They are designed for applications requiring asynchronous and simultaneous read/writes in multiprocessing, rate buffering and other applications.
