The 18-bit bus is uni-directional and depth- and width-expandable. The part is marked obsolete by the manufacturer. It supports retransmit capability and programmable flags — features that simplify frame-level flow control in a FIFO buffer chain. ## 64-LQFP footprint and 5 V supply rail The supplier device package is 64-TQFP (10x10). The 5 V supply rail is non-negotiable — this part does not operate at 3.3 V. Temperature range is commercial: 0°C to 70°C. The CY7C4275-10ASC is officially obsolete. No successor part number or cross-reference is listed by Infineon. Available inventory is sourced through independent surplus channels; quantities are lot-specific and confirmed at RFQ.","metaTitle":"Infineon CY7C4275-10ASC Sync FIFO, 576K, 100MHz, 64-LQFP","metaDescription":"Infineon CY7C4275-10ASC synchronous FIFO memory, 576K (32K x 18), 100MHz data rate, 8ns access time, 5V supply.
