At 400 MHz, the DDR II+ interface transfers data on both clock edges, effectively doubling the data rate to 800 MT/s per pin. For an 18-bit bus, that translates to a raw bandwidth of 14.4 Gbit/s. The synchronous architecture eliminates the dead cycles you get with asynchronous SRAM on back-to-back reads or writes, which matters when a switch ASIC is doing table lookups every few nanoseconds. The trade-off: the 165-LBGA (13x15mm FBGA) demands careful PCB layout — tight impedance control on the data lines and a clean 1.8V supply with adequate decoupling right at the BGA pads.","metaTitle":"CY7C1248KV18-400BZXC 36Mbit DDR II+ SRAM, 400 MHz, 165-LBGA","metaDescription":"Infineon CY7C1248KV18-400BZXC synchronous SRAM, 36Mbit (2M x 18), DDR II+ parallel interface, 400 MHz clock, 1.7-1.9V supply, 165-FBGA.
