100 MHz synchronous FIFO for 5V logic systems
The CY7C4245-10ASXCT is a 72K (4K x 18) synchronous FIFO from the CY7C series, clocking at 100 MHz with an 8 ns access time. That 100 MHz data rate means it can sustain a 100 million words-per-second transfer rate on a 5V bus, which is the key spec for buffer applications in legacy telecom or industrial controllers where the rest of the logic still runs on 5V rails.
Infineon lists the CY7C4245-10ASXCT as Obsolete. For BOM lines that still call out this exact order code, the only sourcing path is through independent distribution or the spot market — we can source and quote it to order against your quantity.
Retransmit and programmable flags for flow control
This FIFO supports retransmit capability and programmable flags. Retransmit lets you re-read the same data word without a full reset — useful in packet retry schemes. Programmable flags (almost-full, almost-empty) give the system designer hysteresis-based flow control rather than relying on the full/empty flags alone. The 45 mA max supply current is modest for a 5V synchronous part.
Commercial temperature range and 5V-only operation
Supply voltage is 4.5V to 5.5V, so it is not 3.3V-compatible on the core or I/O. If your system runs on 3.3V logic, this part will need level translation or a separate 5V rail.
