633 MHz QDR II+ SRAM — what the clock rate buys you
That clock rate, combined with the double-data-rate I/O on the QDR II+ bus, delivers a peak read/write bandwidth that keeps a high-performance network processor or FPGA fabric fed without wait-state stalls.
4M x 18 organization — bus width check
Organized as 4M words by 18 bits, this part serves applications that need a narrower data bus than the common x36 QDR offerings. The 18-bit width suits processors or ASICs with a half-word or byte-oriented memory interface — confirm that your controller expects an x18 port before committing the BOM.
Operates from 1.7 V to 1.9 V, which aligns with the 1.8 V nominal core rail used in many contemporary FPGAs and ASSPs.
Supplied in a 165-ball FBGA, 13x15 mm body. The 0.80 mm ball pitch is standard for this density class; a 4-layer PCB with microvia fan-out under the BGA is typical.
