Infineon lists the CY7C1021CV33-10BAXI as Obsolete. For a BOM that requires this exact order code, the only channel is independent distribution — surplus inventory that was manufactured before the EOL cutoff. Sourcing through a broker that screens for date code freshness and counterfeit risk is the standard approach for this status.
1 Mbit organized 64K x 16 — bus width fit
Organised as 64K words of 16 bits, this SRAM connects directly to a 16-bit data bus without external muxing. The 1 Mbit density suits moderate-depth buffering, look-up tables, or scratchpad memory in embedded systems — not large frame buffers or deep FIFO applications.
No exposed thermal pad; all dissipation is through the BGA balls into the PCB copper.
