The 1.7V to 1.9V core supply and 165-ball FBGA (13x15 mm) footprint place it squarely in the mid-2000s high-performance SRAM generation, before RLDRAM and HBM displaced this class in many designs. ## 333 MHz and the bus margin decision At 333 MHz the clock period is 3 ns, and the QDR II interface leaves less than half that for signal-integrity margin after accounting for output hold and setup windows. Board-level routing must match the fly-by topology the datasheet recommends — any stub or via mismatch eats into the already tight timing budget. The 1.7V–1.9V supply range is narrower than a standard 1.8V rail's tolerance, so the regulator needs to stay inside ±50 mV at the SRAM balls; a 1.8V rail that dips to 1.65V during transient load will push the part out of spec. ## Industrial temperature grade — what it buys you ## Obsolete — last-time-buy and surplus sourcing Infineon (formerly Cypress) has listed the CY7C1415KV18-333BZI as obsolete. No official successor part number appears in the lifecycle record, so a drop-in replacement from the same manufacturer is not guaranteed.","metaTitle":"Infineon CY7C1415KV18-333BZI QDR II SRAM, 36Mbit, 333 MHz","metaDescription":"Infineon CY7C1415KV18-333BZI is a 36Mbit synchronous QDR II SRAM with 333 MHz clock, 1.7V–1.9V supply, industrial temp.
