The 8 ns access means the first word appears on the output bus within 8 ns of the read clock edge — critical for back-to-back reads in a pipelined system where the downstream logic must latch data within the same clock cycle. Infineon lists the CY7C4255V-10ASC as Obsolete. Quantities are lot-specific and confirmed at RFQ. No stock-holding claim — sourced per order against a BOM line. ## 64-TQFP package and board-fit Housed in a 64-LQFP (supplier device package 64-TQFP, 14x14 mm body), surface-mount. The 0.8 mm pitch is routable on a standard 4-layer PCB without microvias. ## Depth/width expansion and retransmit Supports depth and width expansion via the Expansion In/Out pins, allowing multiple devices to cascade for larger FIFO depth or wider data bus. Retransmit capability lets the host re-read the same data word without a full reset — useful in packet retry logic. Programmable flags (Almost Full, Almost Empty) are available, giving the controller early warning before the FIFO reaches its boundary.","metaTitle":"Infineon CY7C4255V-10ASC 144K Sync FIFO, 8ns Access","metaDescription":"Infineon CY7C4255V-10ASC synchronous FIFO, 144K (8K x 18), 100 MHz, 8 ns access.
