The CY7C419-10JXC is a 2.25 Kbit (256 x 9) asynchronous FIFO with 10 ns access time and 50 MHz data rate. It buffers data between two clock domains without FWFT support, using depth and width expansion for larger arrays.
Obsolete — sourcing reality for this FIFO
The CY7C419-10JXC is marked obsolete. No official successor is listed in the record.
Package and temperature — fit for the board
The package measures 11.43 x 13.97 mm. It is a surface-mount, leaded carrier — rework is straightforward with a hot-air station, but the J-lead footprint is less common on modern boards than QFP or BGA.
