Infineon (formerly Cypress) lists the CY7C1568KV18-400BZXI as Obsolete.
The 400 MHz clock rate delivers back-to-back read/write throughput without dead cycles between bus turnarounds — the defining advantage of the DDR II+ family over standard NoBL or QDR parts.
The 165-ball FBGA (13x15 mm body) uses a 1.0 mm ball pitch — standard for mid-density BGA routing on a 4- or 6-layer board.
We source CY7C1568KV18-400BZXI to order through independent distribution. Submit an RFQ for current availability and pricing — we confirm both at quote time.
Infineon has not published an official successor order code for this part. The DDR II+ family has been superseded by later-generation synchronous SRAM architectures; a pin-compatible drop-in replacement is not available. Any alternate would require a board respin and requalification.
