The DDR II+ interface delivers data on both clock edges, so the effective data rate is 800 MT/s per I/O pin — the 36-bit-wide bus sustains 28.8 Gbit/s raw throughput, which sets the bandwidth ceiling for the buffer or cache it feeds. The 1.7V–1.9V supply rail keeps the core power draw in check for a 400 MHz synchronous part, but the I/O bank also runs at the same VDDQ — no separate I/O voltage, so the supply rail must be shared cleanly with the controller. Operating temperature is 0°C–70°C (commercial grade), which covers most indoor networking and compute equipment but not extended industrial or automotive environments. ## Package and board-fit — 165-FBGA landing pattern The part ships in a 165-ball LBGA (13x15 mm body per the supplier device package designation). The tray packaging means the parts are delivered in JEDEC trays, not tape-and-reel, so the pick-and-place feeder setup expects a tray handler or waffle-pack adapter.","metaTitle":"Infineon CY7C1270KV18-400BZXC 36Mbit DDR II+ SRAM, 400 MHz","metaDescription":"Infineon CY7C1270KV18-400BZXC synchronous DDR II+ SRAM, 36Mbit, 1M x 36, 400 MHz clock, 1.7V-1.9V supply, 165-FBGA.
