Product details

It runs at 100 MHz with an 8.5 ns access time, eliminating the dead cycle between read and write operations that conventional pipelined SRAMs require. 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.

Frequently asked questions

What is the replacement for CY7C1371D-100AXC?

No official replacement order code is listed in the available records. A current-production synchronous SRAM with similar density and NoBL-like operation in a 100-TQFP package would need to be evaluated for pin compatibility and timing, but no drop-in substitute is documented.

What is the access time of CY7C1371D-100AXC?

The access time is 8.5 ns at a 100 MHz clock frequency, which means data is available within one clock cycle from address assertion with no read-write turnaround penalty.
