High-bandwidth buffer for networking and telecom
It clocks at 167 MHz over a parallel interface, giving you back-to-back read and write throughput without dead cycles — the whole point of the QDR II bus. This part lives in high-bandwidth data-path applications: switch fabric buffers, line-card packet memory, and telecom framers where the bus needs to keep both read and write pipes open every cycle.
1.8 V supply, commercial temperature — indoor gear only
That means controlled indoor environments: central offices, data centres, lab equipment.
165-ball FBGA — plan the rework flow
Packaged in a 165-ball FBGA (15x17 mm body). That is a fine-pitch BGA — you will need x-ray inspection post-reflow and a hot-air station with a profile for lead-free balls if you are reworking. No exposed paddle, so thermal management is through the board vias under the package.
That means Cypress (now Infineon) is still manufacturing this part — no last-time-buy notice, no end-of-life clock ticking. For a BOM line, that removes the single-source obsolescence risk for current production runs. The base product number is CY7C1414, so density and speed variants share the same footprint if you need to scale up or down later.
