It clocks at 133 MHz with a 4.2 ns access time. ## Active production — no LTB risk The 71V3558S133BG carries an Active lifecycle status. No last-time-buy notice or end-of-life announcement is on record. ## Commercial temperature grade — indoor equipment only Rated 0°C to 70°C, this SRAM is suited for controlled indoor environments: central-office telecom, data-center switches, test equipment, and server-class cache. Not rated for outdoor base stations, motor drives, or automotive under-hood use. The 119-PBGA package requires a multi-layer PCB with via-in-pad or microvia breakout for the fine-pitch balls.","metaTitle":"71V3558S133BG SRAM 4.5Mbit 133 MHz 4.2 ns 119-PBGA","metaDescription":"71V3558S133BG synchronous ZBT SRAM, 4.5 Mbit (256K x 18), 133 MHz clock, 4.2 ns access, 3.3 V, 119-PBGA.
