Product details

Synchronous ZBT SRAM for high-throughput buffer applications

The Renesas 71V3558S133BG is a 4.5 Mbit synchronous SRAM organized 256K x 18, built on ZBT (Zero Bus Turnaround) technology. 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.

Frequently asked questions

What is the memory configuration of the 71V3558S133BG?

The 71V3558S133BG is organized as 256K words by 18 bits, for a total of 4.5 Mbit. The 18-bit width supports a 16-bit data word plus two parity bits, common in networking buffer applications.

What is the clock frequency of the 71V3558S133BG?

The 71V3558S133BG operates at a 133 MHz clock frequency, with a 4.2 ns access time.
