The CY7C1321KV18-333BZC is officially listed as Obsolete by Cypress (now Infineon). No last-time-buy window remains open. For a BOM line that needs this exact order code, the only channel is the independent surplus and broker market.
The 165-ball FBGA (13x15 mm) is a fine-pitch BGA. The commercial temperature range (0°C to 70°C) limits this variant to indoor, climate-controlled equipment.
The CY7C1321KV18-333BZXI is the industrial-temperature (-40°C to 85°C) variant in the same 165-FBGA package, but it is also obsolete. No active drop-in replacement exists from Cypress/Infineon. A board redesign to a current-generation QDR or RLDRAM is the recommended path for new designs.
The part is supplied in a Tray and packaged in a 165-ball LBGA (13x15 mm body, 165-FBGA supplier device package).
It is a Synchronous DDR II SRAM, volatile memory, organized as 512K x 36.
