It is designed for high-throughput applications such as network packet buffers, cache memory, and DSP data storage where the processor bus cannot tolerate dead cycles between read and write operations. The NoBL architecture eliminates the turnaround cycle required by conventional synchronous SRAMs, allowing back-to-back reads and writes on every clock edge. ## 133 MHz clock and 4 ns access — what they mean for timing closure At 133 MHz the clock period is roughly 7.5 ns, and the 4 ns access time leaves about 3.5 ns of setup margin for the receiving logic — enough for most FPGA and ASIC interfaces without needing a separate PLL phase shift. The 3.135V to 3.6V supply range means the part runs comfortably on a nominal 3.3V rail with typical ±5% regulation, though the lower end of the range should be checked against the regulator's accuracy at full load. The 36-bit wide data bus suits 32-bit processors with parity or ECC, or 36-bit networking data paths. It is not specified for industrial or automotive environments where the ambient may exceed 70°C or dip below freezing. Supplied in a 100-pin LQFP (supplier device package 100-TQFP, 14x20 mm body) for surface-mount assembly.","metaTitle":"Cypress CY7C1350G-133AXC NoBL SRAM, 4.5Mbit, 133 MHz","metaDescription":"Cypress CY7C1350G-133AXC NoBL synchronous SRAM, 4.5Mbit (128K x 36), 4 ns access time, 133 MHz clock, 3.3V, 100-TQFP.
