Its 250 MHz clock rate delivers back-to-back read and write transactions on separate ports without dead cycles, making it a fit for high-throughput data buffers in networking switches, baseband processors, and test equipment where the bus turnaround overhead of traditional SRAM would cost bandwidth.
Housed in a 165-ball FBGA (15 x 17 mm body), this part is surface-mount only and requires a controlled reflow profile.
No official replacement part number is listed in the record. For new designs, consider current-generation QDR II+ or QDR IV synchronous SRAMs from Infineon that offer similar density and 250 MHz clock rates in a 165-ball FBGA package, but verify pin compatibility and supply voltage (1.7 V–1.9 V) against your layout.
