71V416S15BEG8

Overview

The Renesas Electronics Corporation 71V416S15BEG8 is a 4 Mbit (256K x 16) asynchronous static random-access memory (SRAM) IC. It operates on a single 3.3 V power supply with a voltage range of 3.0 V to 3.6 V. The device features a maximum access time of 15 ns and a maximum operating frequency of 66 MHz. It utilizes a parallel interface and is housed in a 48-CABGA package. The component supports an industrial temperature range from -40°C to +85°C.

Feature Summary

• Fully static asynchronous operation requiring no clock signals or periodic refresh cycles for data retention.
• LVTTL-compatible bidirectional inputs and outputs ensuring direct interfacing with standard logic families.
• Center power and ground pinout configuration designed to minimize noise and improve signal integrity.

Applications

• High-speed buffering in telecommunications equipment
• Cache memory implementation in embedded systems
• Data storage in industrial control units

Procurement Notes

Verify the specific suffix 'G8' against official Renesas documentation, as it may indicate lead-free status or specific packaging variations. Confirm RoHS compliance and moisture sensitivity levels prior to assembly. Check for end-of-life notices or obsolescence warnings, as this component family has faced discontinuation events. Ensure compatibility with existing PCB footprints and reflow profiles.

Selection Notes

Select this part when a 256K x 16 organization is required with 15 ns speed performance. It is suitable for designs needing LVTTL compatibility and center power/ground pinouts. Compare against other 71V416 variants if different packages or temperature ranges are needed. Verify that the 3.3 V supply voltage aligns with the system architecture.

Part Context

This component belongs to the Renesas 71V416 series of high-speed CMOS SRAMs. The series offers various access times and package options to suit different design constraints. The 71V416S15 variant specifically targets applications requiring 15 ns performance within the industrial temperature range.

Replacement Considerations

Official substitutes include the 71V416S15BEI8 and 71V416S15PHGI8, which share identical electrical specifications but differ in package type (CABGA vs TSOP). Verify pinout compatibility before substitution.
