This part is marked obsolete by Cypress. If you are qualifying a new design, look at current-generation synchronous FIFOs from Cypress (now Infineon) or IDT (now Renesas) in a similar 64-LQFP footprint — but verify pin compatibility against the datasheet, as no direct drop-in replacement is documented here. ## Retransmit and programmable flags Supports retransmit capability, which lets you re-read a block of data from the FIFO without resetting the pointer — useful in packet retry or error-recovery sequences. Programmable flags (almost-full, almost-empty) give the host controller early warning before the FIFO overflows or underflows, reducing the interrupt load on the processor. Housed in a 64-LQFP package, surface-mount only.","metaTitle":"Cypress CY7C4245-10AXI Synchronous FIFO, 100 MHz, 8 ns, 72K","metaDescription":"Cypress CY7C4245-10AXI synchronous FIFO memory, 72K (4K x 18), 100 MHz data rate, 8 ns access time, 5 V supply, -40°C to 85°C, 64-LQFP.
