NoBL pipeline — why the dead cycle disappears
The CY7C1474BV33-200BGXC is a 72 Mbit synchronous SRAM from Infineon's NoBL™ (No Bus Latency) family, organized 1M x 72. The NoBL pipeline lets the memory accept a new read or write address on every clock cycle without inserting a dead cycle between read-to-write or write-to-read transitions — the bus stays full at 200 MHz. For a system architect sizing the memory bus, the 200 MHz clock rate sets the peak bandwidth at 1.6 GB/s (200 MHz × 72 bits ÷ 8). The 3 ns access time from address to valid data means the first read latency is three cycles; after that, the pipeline delivers one 72-bit word per clock.
The commercial temperature grade (0 °C to 70 °C) limits this part to indoor, climate-controlled environments — no extended temp for telecom cabinets or outdoor base stations. The 209-ball FBGA (14 mm × 22 mm) uses a 1.0 mm ball pitch. A pcb_layout_engineer should budget four signal layers for fan-out; the inner balls on a 14×22 array require microvias or buried vias in a standard 8-layer stack-up.
Active lifecycle — no end-of-life pressure
Infineon lists the CY7C1474BV33-200BGXC as Active (current production). The base product number CY7C1474 covers multiple speed grades and temperature ranges; the -200BGXC suffix identifies the 200 MHz, commercial-temp, 209-FBGA variant in tray packaging.
