Asynchronous SRAM for industrial control and communications
The parallel interface and 10 ns write cycle time suit it for cache buffers, packet memory, and real-time control loops in industrial automation, telecom line cards, and test equipment where deterministic latency matters.
For a 66 MHz bus, the part delivers a full cycle of margin, so no additional pipeline registers are needed.
Supply voltage range and power rail compatibility
At 3.3 V the part runs at full speed; at 2.5 V the access time may degrade slightly but remains within the 10 ns spec across the full temperature range. This flexibility simplifies dual-voltage designs where the SRAM shares a rail with an FPGA or SoC I/O bank.
The base product number CY7C1049 covers multiple speed grades and temperature ranges, so the -10ZSXIT suffix identifies the 10 ns, industrial-temperature, Tape & Reel variant.
