The part operates from a 3.135 V to 3.6 V supply and is specified over the commercial temperature range of 0°C to 70°C, typical for indoor rack-mount or bench-top equipment. The 8.5 ns access time at 100 MHz clock means the SRAM delivers data within one clock cycle from address assertion, with no wait states inserted for read-to-write turnaround. In a system where the memory controller expects zero dead cycles — common in high-speed FIFO or look-up table implementations — this part keeps the pipeline full. If your design can tolerate a one-cycle turnaround penalty, a conventional synchronous SRAM with the same density may be cheaper; if throughput is the constraint, the NoBL feature is worth the premium. ## Obsolete — sourcing reality for this BOM line The CY7C1371D-100AXC is marked obsolete by the manufacturer.","metaTitle":"Infineon CY7C1371D-100AXC 18Mbit NoBL SRAM, 8.5 ns","metaDescription":"Obsolete Infineon CY7C1371D-100AXC synchronous SRAM, 18Mbit, 512K x 36, 100 MHz, 8.5 ns access, 100-TQFP.
