The NoBL architecture means the controller can issue a write on the clock cycle immediately following a read without inserting an idle cycle — a feature that lifts sustained throughput in packet-processing and FIFO applications where the bus direction flips frequently. For the system architect, this translates to higher effective bandwidth than a standard synchronous SRAM at the same clock rate, without needing a DDR interface. It is not rated for outdoor telecom cabinets, factory floor, or under-hood automotive use. If the application sees ambient above 70°C or below freezing, the industrial-temperature sibling CY7C1463KV33-133AXI (same package, -40°C to 85°C) is the correct drop-in replacement. ## Supply rail and decoupling considerations At 133 MHz the core draws transient current during each clock cycle; the 100-TQFP package has a central ground and VDDQ ring. Place a 0.1 µF ceramic cap per supply pin pair and a 10 µF bulk cap near the package edge. The PCB layout engineer should keep the trace from the regulator to the SRAM supply pins under 1.5 inches to minimize IR drop at switching edges. This is a current-production part, not a last-time-buy or obsolete line.","metaTitle":"Infineon CY7C1463KV33-133AXC 36Mbit NoBL SRAM, 133 MHz","metaDescription":"Infineon CY7C1463KV33-133AXC 36Mbit synchronous SRAM with NoBL architecture, 133 MHz clock, 6.5 ns access.
