It is no longer manufactured by Infineon, but it remains available through surplus and independent distribution channels. We can source it to order against an RFQ."},{"question":"What is the replacement for CY7C199C-15VXC?","answer":"Infineon has not published a direct pin-compatible successor for this specific ordering code. For a new design, consider the active members of the CY7C199 family, but verify supply voltage (3.3V vs 5V) and package compatibility. For a drop-in replacement on an existing board, the best path is to source the original part through surplus channels."},{"question":"Can CY7C199C-15VXC be used in a 5V system?","answer":"Yes, the CY7C199C-15VXC is rated for a 4.5V to 5.5V supply, so it connects directly to 5V logic without level translation."},{"question":"What are the exact specifications of CY7C199C-15VXC?","answer":"The CY7C199C-15VXC is a 256Kbit asynchronous SRAM organized as 32K x 8 bits, with a 15 ns access time, parallel interface, 4.5V to 5.5V supply, 0°C to 70°C operating temperature, and a 28-SOJ surface-mount package."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/infineon/CY7C199C-15VXC","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/infineon/CY7C199C-15VXC when reusing this data.
