The CY7C4291V-15JXC is a 1.125 Mbit synchronous FIFO organized as 128K x 9 bits, clocked at 66.7 MHz with a 10 ns access time.
The device supports depth and width expansion. Programmable flags are available for flow-control handshaking.
No official replacement part number has been published for this specific density and speed grade. The part is sourced from surplus or broker inventory against an RFQ.
The JXC suffix in the order code indicates a lead-free, RoHS-compliant finish. The part is listed as RoHS compliant.
No. The supply range is 3 V to 3.6 V. Operating at 5 V exceeds the absolute maximum ratings and will damage the device.
