71V416L10YG8

Overview

The Renesas Electronics Corporation 71V416L10YG8 is a 4 Mbit (256K x 16) asynchronous static random-access memory (SRAM) device. It operates on a single 3.3V power supply with a voltage range of 3.0V to 3.6V. The component features a 10 ns access time and is housed in a 44-pin Small Outline J-Lead (SOJ) package designed for surface-mount technology. It supports an industrial operating temperature range from -40°C to +85°C. Maximum supply current is specified at 180 mA. The device utilizes LVTTL-compatible bidirectional I/Os and requires no clock or refresh cycles.

Feature Summary

• Fully static asynchronous operation eliminating the need for external clocks or periodic refresh cycles
• Single 3.3V CMOS power supply compatibility with LVTTL-compatible bidirectional inputs and outputs
• Industrial-grade wide temperature range capability suitable for demanding environmental conditions

Applications

• High-speed data buffering in embedded systems
• Cache memory implementation in microcontroller-based designs
• Data storage in industrial control equipment

Procurement Notes

Verify component authenticity through authorized distributors due to End-of-Life status. Confirm moisture sensitivity level handling procedures during assembly. Ensure packaging integrity matches reel or cut-tape specifications. Validate RoHS compliance documentation against current regulatory requirements. Cross-reference datasheet revisions to confirm pinout consistency.

Selection Notes

Select this part for applications requiring fast asynchronous access without clock synchronization. Compare against TSOP packages if board space constraints differ. Verify voltage tolerance matches system power rails. Consider thermal dissipation capabilities within the SOJ footprint. Evaluate replacement availability given the discontinuation notice.

Part Context

This component belongs to the 71V416 series of high-speed SRAMs manufactured by Renesas Electronics. The series offers various access times and package options including TSOP and SOJ configurations. The 71V416L variant specifically denotes industrial temperature rating. This family provides non-volatile-like speed with volatile memory density for temporary data retention.

Replacement Considerations

Official substitutes include 71V416L10PHGI and 71V416L15PHGI. These alternatives share identical electrical characteristics but utilize TSOP-44 packages instead of SOJ. Verify mechanical fitment before substitution.
