The 4.5V–5.5V supply range confirms this is a 5V-only part; it does not operate at 3.3V. ## Obsolete — no official successor on record No pin-compatible successor has been assigned by the manufacturer — the base product number CY7C199 family has no direct replacement in the current Infineon SRAM portfolio. For existing BOM lines, the procurement path is through independent surplus and authorized-distributor excess inventory. A board redesign to a 3.3V asynchronous SRAM (e.g., a 256Kbit x 8 in TSOP or BGA) is the typical migration path for new builds.","metaTitle":"Infineon CY7C199C-15VXI 256Kbit SRAM, 15 ns, 28-SOJ","metaDescription":"Infineon CY7C199C-15VXI 256Kbit asynchronous SRAM, 32K x 8, 15 ns access, 4.5V–5.5V, -40°C to 85°C, 28-SOJ.
