The 100 MHz clock means the FIFO can accept or deliver one 18-bit word every 10 ns, which matches the bus speed of many mid-range DSPs, FPGAs, and ASICs. The 8 ns access time is the time from the read-enable edge to valid data on the output bus — budget this into your setup/hold timing at the receiving device. The 64K x 18 memory depth gives 1.125 Mbits of buffering, enough for a few thousand 18-bit samples or a line of video data in a 640-pixel display. The supply range is 3.0 V to 3.6 V, typical for 3.3 V logic families. The maximum supply current is 30 mA, so the power dissipation is under 100 mW — no special thermal management needed in the 64-LQFP package. ## Retransmit and programmable flags — design flexibility The CY7C4285V-10ASC supports retransmit capability, which lets you reset the read pointer to the beginning of the stored data without clearing the FIFO — useful for retrying a data packet after a transmission error. It also supports programmable flags, so you can set the almost-full and almost-empty thresholds to match your system's watermarks. Expansion is possible in depth or width, meaning multiple FIFOs can be cascaded for larger buffers or wider data paths. ## Package and footprint — 64-LQFP Mounting is surface mount.","metaTitle":"CY7C4285V-10ASC Infineon Synchronous FIFO 64Kx18 100MHz","metaDescription":"CY7C4285V-10ASC synchronous FIFO, 64Kx18, 100 MHz, 8 ns access, 3.0-3.6 V, 64-LQFP.

We do not carry stock on the shelf, but we can source it through our independent distribution network. Submit an RFQ with your target quantity and delivery timeline — we will search our supply chain for available units and return a quote. No official successor is listed, so if you need this exact FIFO, the independent channel is the only option."},{"question":"What is the replacement for the CY7C4285V-10ASC?","answer":"Infineon has not published an official replacement or cross-reference for the CY7C4285V-10ASC. If you are designing a new board, look at current-generation synchronous FIFOs from Infineon or other suppliers with a 64K x 18 or similar configuration, 100 MHz or faster data rate, and 3.3 V supply. For an existing BOM, the safest path is to source the original part through independent distribution."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/infineon/CY7C4285V-10ASC","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/infineon/CY7C4285V-10ASC when reusing this data.
