256K x 36 synchronous SRAM for high-throughput cache and buffer applications
The Infineon (Cypress) CY7C1354CV25-200AXCT is a 9 Mbit NoBL™ (No Bus Latency) synchronous SRAM organized as 256K words by 36 bits. The 200 MHz clock frequency and 3.2 ns access time target high-speed memory subsystems in networking, telecom, and FPGA-based designs where back-to-back read/write throughput without dead cycles is required.
The 200 MHz clock rate sets the maximum operating frequency for the synchronous interface. At this speed, the 3.2 ns access time from clock edge to data valid is the critical path for setup-and-hold closure on the memory bus. A 200 MHz pipeline with a 36-bit data word means the bus can sustain 7.2 Gbit/s of raw throughput, but the actual margin depends on board trace length, load capacitance, and the controller's input timing. For a new design, this part is obsolete — see the lifecycle section for sourcing options.
Obsolete — last-time-buy and surplus channel sourcing
The CY7C1354CV25-200AXCT carries an official lifecycle status of Obsolete. For existing BOM lines, procurement should plan for last-time-buy or surplus/broker channel sourcing.
100-TQFP footprint and 2.5 V supply rail
Packaged in a 100-lead TQFP (14x20 mm body), the CY7C1354CV25-200AXCT is a surface-mount device intended for reflow soldering. The 2.5 V supply rail is narrow (±5% around 2.5 V) and must be generated from a dedicated regulator — it cannot share a 3.3 V or 1.8 V rail without level translation.
