Product details

256Kbit asynchronous SRAM for 5V parallel buses

The 15 ns access time means this part can keep up with fast 5V CPLDs, legacy microcontrollers, and DSPs without inserting wait states, preserving bus throughput in timing-constrained designs.

Sourcing reality: end-of-life part

The CY7C199C-15PC is flagged at end-of-life (EOL) stage. While the manufacturer status lists it as active, the EOL hot designation indicates production is winding down or has ceased. For a BOM freeze or long-term production run, validate a pin-compatible second source or drop-in replacement from the same 32K x 8 asynchronous SRAM family. No official successor order code is listed.

5V-only supply — plan the rail accordingly

Not rated for industrial enclosures, outdoor telecom cabinets, or automotive under-hood environments.

Frequently asked questions

What supply voltage does CY7C199C-15PC require?

It requires a 4.5V to 5.5V supply rail. It is not compatible with 3.3V or lower-voltage logic systems without level translation.
