Synchronous FIFO — 4.5 Kbit, 100 MHz, 32-TQFP
The CY7C4211-10AXI is a synchronous FIFO from the CY7C series, organized as 512 words by 9 bits for a total memory size of 4.5 Kbit. It operates at a 100 MHz data rate with an 8 ns access time, making it suited for high-speed buffering in data acquisition, telecom, and video processing pipelines where the read and write clocks run independently. The part is now classified as Obsolete by the manufacturer, meaning new designs should not target this order code — existing BOM lines can be supported through independent distribution channels.
Supplied in a 32-TQFP package (7x7 mm body), the 0.8 mm pitch QFP footprint is a standard surface-mount layout that places without tombstoning on a typical lead-free reflow profile — check the MSL rating before the bake decision. The synchronous architecture supports depth and width expansion via the expansion-in/expansion-out pins, so multiple devices can cascade without external glue logic — useful when the 512-word depth is insufficient for the buffer requirement.
