It is a volatile memory device with a parallel interface, designed for high-bandwidth buffer and cache applications in networking, telecom infrastructure, and high-performance computing. The 933 MHz clock rate is the defining performance spec for this QDR IV SRAM. At this speed, the memory delivers a data rate of 1.866 Gbps per pin on a double-data-rate bus, which translates to an aggregate bandwidth of roughly 67 GB/s on the 36-bit-wide data path. For a systems architect, this clock frequency drives the signal-integrity budget on the PCB: trace lengths must be matched within a few millimetres, and the 361-FCBGA package demands a controlled-impedance stack-up with adequate decoupling near the BGA balls. The 1.26V to 1.34V core supply is tight — a 1.3V nominal rail with ±3% regulation is typical — so the power design needs a low-noise LDO or a dedicated DC-DC converter with good transient response. The tray shipping format means the parts arrive in antistatic trays, not tape-and-reel — plan for pick-and-place handling or manual placement if your line is set up for reels. The base product number CY7C4142 covers a family of QDR IV density and speed variants; if a different density or speed grade is needed, the same footprint and interface apply across the family.","metaTitle":"Infineon CY7C4142KV13-933FCXI QDR IV SRAM, 144 Mbit, 933 MHz","metaDescription":"Infineon CY7C4142KV13-933FCXI QDR IV synchronous SRAM, 144 Mbit (4M x 36), 933 MHz clock, industrial temp -40 to 85°C, 361-FCBGA.
