71V35761SA166BGI

Overview

The Renesas 71V35761SA166BGI is a synchronous single-data-rate static random-access memory (SRAM) IC. It provides a total storage capacity of 4.5 Mbit, organized as 128K words by 36 bits. The device supports a maximum clock frequency of 166 MHz with a typical access time of 3.5 ns. It operates on a 3.3V power supply, with a voltage range of 3.135V to 3.465V. The component utilizes a parallel interface and is housed in a 119-pin plastic ball grid array (PBGA) package measuring 14x22 mm. It is rated for an operating temperature range from -40°C to +85°C.

Feature Summary

• Supports high-speed synchronous burst operations at frequencies up to 166 MHz
• Features pipelined architecture for fast data throughput
• Includes global write control and byte write enable capabilities

Applications

• High-performance embedded systems requiring fast real-time data buffering
• Industrial equipment with strict timing constraints
• Network infrastructure components needing rapid packet processing

Procurement Notes

This specific part number is officially listed as End-of-Life (EOL). Verification of current availability requires checking authorized distributors for remaining stock or obsolete inventory. Ensure that any sourced units are genuine Renesas products and verify the moisture sensitivity level handling requirements before assembly.

Selection Notes

Select this component when a wide 36-bit data bus is required for system integration. The synchronous interface simplifies timing design compared to asynchronous alternatives. Consider the 119-pin PBGA footprint during PCB layout. Verify that the 3.3V logic levels match the host processor's I/O specifications.

Part Context

The 71V35761S series represents Renesas' high-performance synchronous SRAM family. This model belongs to the SDR category, designed for applications demanding low latency and high bandwidth. The 'SA' suffix typically denotes specific speed grades or packaging variations within the broader product line.

Replacement Considerations

Official substitutes include other members of the 71V35761S family with compatible pinouts and electrical characteristics. Cross-reference datasheets for equivalent access times and organization formats.
