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. ## Package and temperature grade 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.","metaTitle":"Cypress CY7C1321KV18-333BZC SRAM, 18Mbit, 333 MHz, 165-FBGA","metaDescription":"Cypress CY7C1321KV18-333BZC 18Mbit Synchronous DDR II SRAM, 333 MHz clock, 512K x 36 organization, 1.7V-1.9V supply, 165-FBGA.
