10 ns asynchronous SRAM for speed-critical data buffers
The CY7C1061GN30-10ZSXI: It operates from a 2.2V to 3.6V supply, so it can sit on a 3.3V or 2.5V rail without an intermediate regulator — useful in mixed-voltage designs where the core logic runs at 3.3V and the I/O bank at 2.5V.
Supply tolerance and bus design
The 2.2V minimum supply means the SRAM holds data down to near the brownout threshold of a 2.5V rail, reducing the need for a separate supervisor reset on the memory alone. Write cycle time matches the access time at 10 ns, so back-to-back reads and writes run at the same bus rate without dead cycles — important for FIFO-style data buffers in imaging or networking gear.
That removes the single-source risk for production builds that need a steady supply of 16Mbit async SRAM.
