What this synchronous SRAM does and where it fits
The Infineon CY7C1440AV33-250AXI is a 36 Mbit synchronous SRAM organized as 1M x 36, clocked at 250 MHz with a 2.6 ns access time. It uses a parallel interface and operates from a 3.135 V to 3.6 V supply. The part is volatile memory — data is lost when power is removed — and is designed for high-bandwidth, low-latency buffering in networking equipment, telecom line cards, and FPGA-based compute accelerators where the wide 36-bit word matches the data bus width of processors or FPGAs that carry parity or ECC bits.
Obsolete — sourcing and lifecycle reality
Infineon has marked the CY7C1440AV33-250AXI as obsolete. There is no official successor order code listed in the lifecycle record. For a BOM that requires this exact part, the only channel is the independent surplus and broker market. We source and quote it to order against an RFQ; availability and current pricing are confirmed at quote time. If your design can tolerate a different footprint or speed grade, a pin-compatible alternative within the same family may exist — but no official replacement is documented here.
