The NoBL architecture eliminates the dead bus cycle between read and write operations, sustaining full 200 MHz throughput without wait states — a key advantage for high-bandwidth data buffers, network switch packet memories, and cache subsystems in telecom and enterprise computing equipment.
3 ns access time at 200 MHz — the timing margin decision
The 3 ns access time at a 200 MHz clock frequency is the headline specification that drives the bus timing closure. In a synchronous SRAM interface, the access time defines how quickly data appears on the outputs after the clock edge. A 3 ns window leaves roughly 2 ns of setup-and-hold margin for a typical FPGA or ASIC controller running at 200 MHz — enough for a clean timing budget on a well-routed board, but tight enough that signal-integrity simulation is recommended before committing the layout. The 36-bit wide data bus means the part can deliver 7.2 Gbit/s of raw bandwidth, which suits it for high-speed packet processing or real-time image frame buffers.
If your design can tolerate a footprint or timing change, a pin-compatible alternative within the same NoBL family may exist, but no direct replacement is documented here.
100-LQFP package and commercial temperature grade
Housed in a 100-LQFP (14x20 mm body, 0.5 mm pitch), the CY7C1470V33-200AXCT uses a surface-mount package suitable for standard reflow assembly. The Tape & Reel (TR) suffix indicates this variant ships on 13-inch reels, typically in quantities suited for production runs rather than prototype sampling.
