71V35761S166BGI8

Overview

The Renesas Electronics Corporation 71V35761S166BGI8 is a synchronous static random access memory (SRAM) device. It features a storage capacity of 4 Mbit organized as 128K x 36 bits. The component supports a maximum clock frequency of 166 MHz with an access time of 3.5 ns. It operates on a single 3.3V power supply, with voltage limits ranging from 3.135 V to 3.465 V. The maximum power consumption current is specified at 330 mA. The device utilizes a parallel interface and is housed in a 119-PBGA package measuring 14x22 mm. It functions within a temperature range of -40°C to +85°C.

Feature Summary

• Supports high-speed synchronous operation with pipelined burst architecture for efficient data throughput.
• Features single-cycle deselect capability to optimize bus utilization during non-active periods.
• Integrates a built-in burst counter to manage sequential memory access patterns automatically.

Applications

• High-performance networking equipment requiring fast packet buffering
• Telecommunications infrastructure systems
• Industrial control systems demanding rapid data processing

Procurement Notes

Verify the specific suffix BGI8 against official Renesas documentation to confirm the exact package type and moisture sensitivity level. Ensure compatibility with existing PCB footprints for the 119-PBGA configuration. Check for any product change notifications regarding substrate or labeling updates that may affect integration. Confirm RoHS compliance status through the manufacturer's latest declarations before finalizing procurement decisions.

Selection Notes

Select this component when a wide data width of 36 bits is required alongside high-frequency synchronous performance. The 166 MHz speed class suits applications needing low latency for large data blocks. Consider the PBGA package constraints for thermal management and board space. Evaluate the 3.3V I/O requirements against system logic levels to ensure proper signal integrity without additional level shifting components.
