It is a volatile memory in a 165-LBGA package (13x15 mm) for surface-mount assembly. The DDR II interface delivers data on both clock edges, effectively doubling the burst rate compared to a single-data-rate SRAM at the same clock frequency. This part is typically specified in networking line cards, telecom switching fabrics, and FPGA-based accelerators where the data bus is 36 bits wide and the system cannot tolerate the access-latency penalty of DRAM. At 250 MHz, the DDR II interface transfers data at an effective 500 million transactions per second on each 36-bit word line. That translates to a peak bandwidth of roughly 18 Gbit/s (2.25 GB/s) per chip — enough to keep a modern FPGA or network processor fed without wait states. The 512K depth by 36-bit width is a natural fit for 36-bit wide memory buses common in high-end FPGAs and ASICs; you can pair multiple devices to build wider or deeper arrays without wasting pins. ## Temperature range and package — where it fits and what the board needs It is the current-speed variant (250 MHz) in the CY7C1321KV18 family.","metaTitle":"Infineon CY7C1321KV18-250BZXC 18Mbit DDR II SRAM, 250 MHz","metaDescription":"Infineon CY7C1321KV18-250BZXC 18Mbit synchronous DDR II SRAM, 250 MHz clock, 512K x 36 organization, 1.7V-1.9V supply, 165-FBGA.

The suffix difference (BZXC vs BZXA) typically indicates a revision or temperature grade change. Verify pin compatibility and timing parameters against your specific board layout and timing budget before substituting. The datasheet revision history should confirm any differences."},{"question":"Does CY7C1321KV18-250BZXC have RoHS compliance?","answer":"RoHS compliance is standard for Infineon's current-production BGA devices. The part number does not carry a lead-free indicator suffix, but the 165-FBGA package is manufactured with lead-free solder balls per industry practice.
