71V65603S133BGG

Overview

The 71V65603S133BGG is a synchronous static random-access memory (SRAM) integrated circuit manufactured by Renesas Electronics Corporation. It features a storage capacity of 9 megabits organized as 256K words by 36 bits. The device operates with a maximum clock frequency of 133 MHz and provides an access time of 4.2 nanoseconds. It utilizes a parallel interface and requires a supply voltage between 3.135V and 3.465V. The component is housed in a 119-pin plastic ball grid array (PBGA) package measuring 14x22 mm, designed for surface-mount installation.

Feature Summary

• Supports high-speed data transfer via a 133 MHz synchronous clock interface
• Provides wide 36-bit data bus width for efficient parallel processing
• Delivers rapid 4.2 ns access latency for low-latency memory operations

Applications

• High-performance computing systems requiring fast cache memory
• Network infrastructure equipment utilizing parallel data buses
• Industrial control systems needing reliable volatile storage

Procurement Notes

Verify the specific package variant and speed grade against current project requirements before procurement. Confirm that the 119-pin PBGA footprint matches the target PCB layout. Check for end-of-life status or obsolescence notices from the manufacturer to ensure long-term supply availability. Ensure compatibility with the 3.3V power domain and signal integrity specifications of the host system.

Selection Notes

Select this component when a 36-bit wide synchronous SRAM interface is required. The 133 MHz speed grade suits applications demanding low latency. Consider the 119-pin BGA package constraints during mechanical design. Evaluate thermal dissipation capabilities within the 0°C to 70°C operating range. Compare pinout compatibility if replacing legacy IDT devices.
