The 250 MHz clock rate and 2.8 ns access time mean the part can deliver a pipelined read or write on every clock edge without inserting a dead cycle between back-to-back operations — the NoBL architecture lets the next access start immediately after the previous one's address is registered, which matters for high-throughput buffer applications like network packet processing or DSP data caches. The commercial temperature range (0°C to 70°C) limits this part to indoor, controlled-environment equipment — not suitable for extended outdoor or under-hood deployment without active cooling. ## Board integration — 100-TQFP footprint and supply routing The 100-TQFP (14x20 mm) package with 0.5 mm pitch requires a 4-layer PCB minimum for fan-out — the inner signal rows need via transitions to inner layers. Place a 0.1 µF ceramic cap within 2 mm of each VDD/VDDQ pair, and a 10 µF bulk cap per quadrant of the package.","metaTitle":"Infineon CY7C1356C-250AXCT 9Mbit SRAM, 250 MHz, 100-TQFP","metaDescription":"Infineon CY7C1356C-250AXCT NoBL synchronous SRAM, 512K x 18, 250 MHz clock, 2.8 ns access.

In a standard synchronous SRAM, a read followed by a write inserts an idle clock; the NoBL architecture lets the next access start on the very next clock edge, improving throughput in pipelined systems like network buffers or DSP data caches."},{"question":"What is the memory organization and access time of the CY7C1356C-250AXCT?","answer":"Organized as 512K x 18 (9Mbit total), with a 250 MHz maximum clock frequency and a 2.8 ns access time.
