71V3577S75BGGI

Overview

The Renesas Electronics Corporation 71V3577S75BGGI is a synchronous static random-access memory (SRAM) device organized as 128K x 36, providing a total storage capacity of 4.5 Mbit. It operates with a maximum clock frequency of 117 MHz and features a fast access time of 7.5 ns. The component utilizes a parallel interface and requires a core power supply voltage ranging from 3.135 V to 3.465 V. It is housed in a 119-pin PBGA package with dimensions of 14x22 mm. The device supports surface mount installation and functions within an operating temperature range of -40°C to +85°C.

Feature Summary

• Supports high-speed synchronous burst operations with flow-through output architecture for minimal latency.
• Includes self-timed write cycles controlled by global write control and byte write enable signals.
• Features low-power standby mode managed by the ZZ input pin to reduce active current consumption.

Applications

• High-performance industrial equipment requiring real-time data processing
• Network infrastructure systems utilizing synchronous memory interfaces
• Embedded control systems needing fast access times for critical operations

Procurement Notes

Verify component authenticity through authorized channels due to end-of-life status. Confirm moisture sensitivity level handling requirements during storage and assembly. Ensure compatibility with existing PCB footprints for the 119-pin PBGA package. Check for RoHS compliance variations across production batches. Validate lead times with distributors as stock levels may be limited.

Selection Notes

Select this component when a 36-bit wide synchronous SRAM interface is required for system integration. Consider the 7.5 ns access time for applications demanding high throughput. Evaluate the 119-pin PBGA package constraints against available board space. Compare performance metrics with alternative devices if newer generations are preferred over obsolete parts.
