It clocks at 167 MHz and uses a parallel memory interface, delivering back-to-back read and write transactions without dead cycles — the defining benefit of the QDR II family for high-throughput buffer applications. It comes in a 165-ball FBGA (15x17 mm) package for surface-mount assembly.
The product status is Obsolete.
The 165-ball FBGA (15x17 mm) package is a fine-pitch BGA requiring controlled reflow profiling and X-ray inspection for solder-joint integrity.
Yes, the official product status is Obsolete. Cypress/Infineon has discontinued production with no last-time-buy window active. Any available units are from surplus or new-old-stock inventory.
The QDR II architecture and 165-ball FBGA footprint are specific enough that a direct pin-compatible substitute from another vendor is not guaranteed. A BOM review with the system architect is recommended to evaluate a current-generation QDR II+ or DDR SRAM alternative that matches the 72Mbit density and 167 MHz speed grade.
