The CY7C419-15VXCT is officially obsolete per Infineon's lifecycle status.
2.25K asynchronous FIFO with 15 ns access
This is a 2.25K (256 x 9) asynchronous FIFO from the CY7C series, with a 15 ns access time and a 50 MHz data rate. The 9-bit width (8 data + 1 parity) suits applications needing error-detection on the fly — common in telecom line cards and industrial backplane buffers where a parity bit travels with the data word.
28-SOJ surface-mount package
Packaged in a 28-BSOJ (0.300", 7.62mm width) — a JEDEC-standard SOJ footprint. The supplier device package is 28-SOJ.
Depth and width expandable with retransmit capability
The FIFO supports expansion in both depth and width, allowing multiple devices to cascade for larger buffers. Retransmit capability is enabled, meaning the part can re-send the same data word without re-loading — useful in retry-on-error protocols or data-recovery loops.
