It clocks at 100 MHz for back-to-back reads and writes, with an 8 ns access time from the read-enable edge. The 9-bit width carries a data byte plus a control or parity bit — useful in telecom or datacom links where an extra flag rides alongside the payload. Programmable almost-empty and almost-full flags let the host set interrupt or DMA thresholds without polling the fill level. ## Industrial temperature range and 5 V supply Maximum supply current is 40 mA at 100 MHz. ## Expansion and flags Depth and width expansion are supported, so multiple CY7C4211s can cascade for deeper or wider buffers. No retransmit or FWFT (First-Word Fall-Through) capability — the first read requires a read-enable cycle after the write. Uni-directional bus direction; the data path flows one way, typical for a rate-matching queue between two clock domains. The CY7C4211-10AXIT is marked obsolete. Cypress (now part of Infineon) no longer manufactures this FIFO. No factory lead time applies.","metaTitle":"Cypress CY7C4211-10AXIT FIFO, 4.5K 512x9, 100MHz, 8ns","metaDescription":"Cypress CY7C4211-10AXIT synchronous FIFO, 4.5K (512 x 9), 100 MHz data rate, 8 ns access, -40 to 85°C.
