72 Mbit QDR II SRAM — what the 333 MHz clock buys you
The CY7C1514KV18-333BZC is a Cypress QDR II synchronous SRAM with 72 Mbit density organized as 2M x 36. The 333 MHz clock rate delivers back-to-back read and write transactions on separate ports without dead cycles — the QDR architecture eliminates the bus-turnaround penalty that standard synchronous SRAMs incur.
Supply rail and temperature — narrow window, clean rail required
Package reality — 165-ball FBGA, 13x15 mm
The 165-FBGA (13x15 mm) is a fine-pitch BGA. The supplier device package is 165-FBGA; the listing also references 165-LBGA. Both refer to the same 13x15 mm body.
Sourcing an obsolete QDR II SRAM
The CY7C1514KV18-333BZC is listed as obsolete. The QDR II family has largely transitioned to QDR II+ and QDR IV, but those are not pin-compatible.
