72Mbit NoBL synchronous SRAM — 200 MHz pipeline, 3 ns access
The CY7C1474BV33-200BGIT: 72Mbit synchronous SRAM from the NoBL family, organized as 1M x 72. Clocks at 200 MHz with 3 ns access time. Supply range is 3.135 V to 3.6 V, rated for -40°C to 85°C.
3 ns access time — what it means for bus timing
3 ns access time at 200 MHz delivers the first word within one clock cycle. Subsequent pipelined words follow at the clock rate. The 14x22 mm ball grid array requires a multi-layer board with controlled impedance.
Obsolete — sourcing reality for this EOL SRAM
Marked obsolete by Infineon. No official successor or direct pin-compatible replacement is listed. Sourcing path is the independent surplus and broker channel. We source and quote this part to order against an RFQ.
NoBL architecture — why it matters for throughput
The NoBL pipeline is a synchronous SDR design that allows the next read or write address to be presented on the same clock edge that the current data is being output. This eliminates the dead bus cycle typical of standard synchronous SRAMs during read-to-write transitions. For a network processor or packet buffer running at 200 MHz, that means sustained throughput without arbitration overhead on every transaction. The trade-off is that the controller must assert the correct command on every clock edge — NoBL does not tolerate idle cycles on the control lines without a deselect.
