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.","metaTitle":"Infineon CY7C199C-15PC 256Kbit SRAM, 15 ns, 28-PDIP","metaDescription":"Infineon CY7C199C-15PC 256Kbit (32K x 8) asynchronous SRAM, 15 ns access time, 4.5V-5.5V, 0°C to 70°C, 28-PDIP.
