That matters when the FPGA or network processor feeding it runs a pipelined datapath that can't tolerate a wait state every time the bus direction flips. The 165-ball FBGA (13x15 mm) footprint is the standard DDR II+ SRAM pinout for this density tier — verify it against your existing board layout if this is a drop-in replacement. It belongs in controlled indoor environments — server rooms, telecom central offices, benchtop test equipment — not in an outdoor base station cabinet or an engine bay. If your system sees -40°C or 85°C+ ambient, you need the industrial-temperature variant from this family.","metaTitle":"CY7C1550KV18-400BZXC SRAM, 72Mbit DDR II+, 400 MHz, 165-FBGA","metaDescription":"Infineon/Cypress CY7C1550KV18-400BZXC synchronous DDR II+ SRAM, 72Mbit (2M x 36), 400 MHz clock, 1.7V-1.9V supply, 165-FBGA.
