This FIFO supports retransmit, meaning the read pointer can be reset to the beginning of the stored data without a full reset. Useful in packet-based systems where a failed transmission needs a replay from the buffer. No FWFT or programmable flags — the flag logic is fixed: full, empty, half-full.
The CY7C419-15JXCT is a 2.25K (256 x 9) asynchronous FIFO with 15 ns access time, 50 MHz data rate, 4.5 V to 5.5 V supply, 65 mA max supply current, retransmit capability, and operates from 0°C to 70°C. It comes in a 32-PLCC (J-Lead) package.
The pinout is standard for a 32-PLCC asynchronous FIFO: data inputs (D0–D8), data outputs (Q0–Q8), read/write enables, full/empty flags, and retransmit control. Refer to the Cypress CY7C419 datasheet for the exact pin assignment.
