Obsolete — last-time-buy window closed
The CY7C1474BV33-167BGIT: The manufacturer's last-time-buy window has passed; no further production is planned. Sourcing now runs through independent distribution — each lot is verified for authenticity and pulled against a confirmed RFQ.
72 Mbit synchronous SRAM — NoBL pipeline
The NoBL (No Bus Latency) architecture eliminates the dead cycle between read and write operations — the next access starts on the clock edge immediately following the previous one, so the bus stays at full utilization without wait states. The 209-FBGA (14x22 mm) footprint demands a controlled-impedance PCB stack-up — the 72-bit-wide data bus at 167 MHz has tight signal-integrity margins on the fly-by topology.
Package and board-fit realities
The Tape & Reel (TR) packaging is the standard carrier for automated pick-and-place; the reel quantity is confirmed at quote time. The parallel memory interface means the 72 data lines plus address and control signals route to the FPGA or ASIC. At 167 MHz, each signal trace length should be matched within ±10 mm to keep setup/hold margins across the bus.
