36 Mbit synchronous SRAM at 250 MHz — what the ratings mean for your BOM
The CY7C1460KV25-250AXC: That 250 MHz clock rate means the memory can sustain a new read or write command every 4 ns in a pipelined burst — the limiting factor in a high-throughput data buffer or network packet memory is the controller's own timing closure, not the SRAM's cycle time. The 36-bit-wide data bus (1M x 36) is a natural fit for processors or ASICs that move 36-bit words — common in parity-protected or ECC memory channels where the extra four bits carry the check code without a second chip. The commercial temperature range (0°C to 70°C) suits controlled indoor environments: telecom central offices, data-acquisition racks, and test equipment that lives in an air-conditioned bay.
Active lifecycle and what it means for procurement
RoHS compliance is confirmed at the ROHS3 level, which exempts lead in solder joints for high-reliability applications where a lead-free finish is not mandatory. No additional compliance documentation (REACH, UL, IEC) is listed in the available record; the RoHS3 declaration is the formal environmental compliance on file.
Where it sits against the NoBL family peers
The CY7C1460KV25-250AXC runs at a higher clock (250 MHz vs 167 MHz) and offers double the memory width (36-bit vs 18-bit), but is limited to commercial temperature — the choice between them hinges on whether the end equipment sees a cold warehouse floor or stays in a climate-controlled room.
