Infineon lists the CY7C1319KV18-250BZC as Obsolete. Buyers should verify the date-code provenance and plan for a board-spin replacement if long-term supply is required.
18 Mbit DDR II+ synchronous SRAM at 250 MHz
It uses DDR II+ (Double Data Rate II+) technology, which clocks data on both rising and falling edges of the 250 MHz input clock, delivering a peak data rate of 500 MHz effective. This makes it suited for high-bandwidth pipelined applications such as network packet buffers, telecom line cards, and high-end test equipment where deterministic random access latency is critical. The parallel memory interface (18-bit data bus) means the part connects directly to a wide memory controller bus — not a serial SPI or QSPI SRAM.
Package, temperature grade, and board-fit
The 0.80 mm ball pitch demands a multi-layer PCB with microvias or blind vias for fan-out; a two-layer board will not route all 165 balls. Supplied in tray packaging.
