Runs on a 133 MHz clock with a 4.2 ns access time, fed from a 3.135 V to 3.6 V supply. 4.2 ns access time at 133 MHz means the SRAM can deliver data within roughly half a clock cycle. That margin absorbs PCB trace delay and output loading without a wait state. Officially obsolete. No last-time-buy window remains open from Cypress (Infineon). Available through independent distribution and surplus channels. Sourced to order against an RFQ. This part belongs in indoor, temperature-controlled equipment: telecom switches, base stations, network routers, or test equipment that lives in a rack or lab.","metaTitle":"Cypress CY7C1382B-133AC 18Mbit Sync SRAM, 133 MHz","metaDescription":"Cypress (Infineon) CY7C1382B-133AC 18Mbit synchronous SRAM, 512K x 36, 4.2 ns access time, 133 MHz clock, 100-LQFP.
