Synchronous FIFO — 66.7 MHz, 11 ns access, 36K depth
The CY7C4241V-15AXC is a synchronous FIFO from the CY7C series, organized as 4K x 9 bits (36K total). It clocks at 66.7 MHz with an 11 ns access time, meaning the read/write cycle completes in under one clock period at full speed — no wait states needed when the FIFO is not full or empty. The 9-bit width suits applications needing a parity or control bit alongside an 8-bit data byte.
No official successor or pin-compatible replacement is listed in the record. Sourcing is through independent distribution — quantities are lot-specific and confirmed at RFQ. The synchronous interface and 66.7 MHz clock rate are the binding constraints for a drop-in replacement.
32-TQFP footprint and commercial temperature range
Housed in a 32-TQFP (7x7 mm) package with a 0.8 mm pitch, the part is surface-mount and reworkable with standard hot-air profiles. The supplier device package is 32-TQFP (7x7).
