DDR II+ SRAM at 550 MHz — the buffer for high-throughput pipelines
The Infineon CY7C2270KV18-550BZXC is a 36Mbit synchronous SRAM built on the DDR II+ architecture, clocked at 550 MHz. It is organized as 1M x 36, giving you a wide 36-bit data bus in a single chip — exactly the sort of part that sits between a network processor and its forwarding table, or between an ASIC and its look-up buffer. The 1.7V to 1.9V core supply keeps the I/O levels in the low-voltage range, consistent with modern 1.8V-logic domains. At 550 MHz the double-data-rate bus transfers data on both clock edges. The 36-bit interface width provides the aggregate bandwidth for a telecom line card or test instrument pipeline.
Package and board integration — 165-FBGA
The surface-mount mounting is standard for high-density boards.
For a new design-in or a production BOM line, this part does not carry the obsolescence risk that haunts older SRAM families.
As an active Infineon part, the CY7C2270KV18-550BZXC is available through the independent distribution channel. There is no allocation or LTB window to chase — the part is a standard catalog item that can be specified into a production BOM with normal supply lead times.
