What is the CY7C1315CV18-167BZC and what does it do?
It clocks at 167 MHz, transferring data on both rising and falling edges of the clock for a peak bandwidth that suits high-throughput buffer applications in networking switches, routers, and telecom line cards. The part operates from a 1.7V to 1.9V core supply and is housed in a 165-ball FBGA (13x15 mm) for surface-mount assembly.
No last-time-buy window remains open from the manufacturer. Any stock in the channel is end-of-life inventory, and replenishment relies entirely on independent-distributor or broker sourcing. If this part is on a current BOM, you should qualify a replacement before stock runs dry — the 167 MHz QDR II interface narrows the drop-in options, so start the cross-reference work now.
Package and temperature — the design envelope
The 165-FBGA (13x15 mm) footprint is standard for QDR II memories of this density. Supply voltage tolerance of 1.7V to 1.9V means a 1.8V rail with ±5% regulation keeps the part in spec; a 1.8V LDO with tight load regulation is the typical pairing.
