18 Mbit synchronous ZBT SRAM for high-throughput buffers
The Renesas 71T75602S200BGG is a 18 Mbit synchronous SRAM organized 512K x 36, built on Zero Bus Turnaround (ZBT) technology. It clocks at 200 MHz with a 3.2 ns access time.
200 MHz clock and 3.2 ns access — timing margin for the bus
The 200 MHz clock rate sets the maximum bus frequency for a zero-wait-state memory transaction. At 3.2 ns access time, the part delivers data within one clock cycle at speed.
Commercial temperature grade — indoor equipment only
Rated 0°C to 70°C, this part is intended for controlled indoor environments — server rooms, central offices, test equipment. Not suitable for outdoor base stations, engine bays, or factory floors without active climate control. The 119-ball BGA footprint requires a multilayer PCB with via-in-pad or microvia capability; plan for X-ray inspection during assembly to verify solder joints under the package.
Active lifecycle — no LTB risk for production runs
The 71T75602S200BGG carries an Active lifecycle status. No end-of-life notice or last-time-buy window is in effect. This part is suitable for both new designs and ongoing production. For dual-sourcing or supply resilience, the ZBT synchronous SRAM family includes multiple density and speed grades sharing the same 119-BGA footprint — verify pin compatibility against the specific controller interface before substituting.
