576K synchronous FIFO — 100 MHz clock, 8 ns access
The Infineon CY7C4275-10ASC is a 576K (32K x 18) synchronous FIFO memory with a 100 MHz data rate and 8 ns access time. 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.
