The Infineon CY7C1412KV18-300BZC is a 36 Mbit synchronous QDR-II (Quad Data Rate II) SRAM organized as 2M × 18 bits, clocked at 300 MHz, and packaged in a 165-ball LBGA (13 × 15 mm) for surface-mount assembly. QDR-II architecture delivers separate read and write data ports, each operating at double data rate, effectively quadrupling the bandwidth of a conventional single-port synchronous SRAM at the same clock frequency.
Obsolete – plan the replacement now
For a production BOM that still needs this part, the channel is limited to surplus and broker inventory. Any stock offered should be checked for date-code freshness and authenticity—mystery lots surfacing years after the last-time-buy window warrant extra scrutiny.
300 MHz clock and 1.7 V–1.9 V supply – design constraints
The 300 MHz clock rate means the memory interface timing budget is tight—trace-length matching and signal integrity on the parallel address/data buses are non-negotiable.
165-ball LBGA footprint and rework notes
The 165-FBGA (13 × 15 mm) package is a fine-pitch BGA. The BGA footprint leaves no room for probe points under the device; all debug access must be routed to vias or test pads on the periphery.
