71V416S10PHGI

Overview

The Renesas Electronics 71V416S10PHGI 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 parallel interface and offers a maximum access time of 10 ns. It is housed in a 44-pin Thin Shrink Small Outline Package (TSOP II). The component supports an industrial operating temperature range from -40°C to +85°C and has a maximum supply current of 200 mA.

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

• Data buffering in high-speed digital systems
• Cache memory implementation in embedded controllers
• Industrial equipment control logic storage

Procurement Notes

Verify the specific package variant, as the suffix PHGI denotes a TSOP-44 form factor. Confirm RoHS compliance status and moisture sensitivity level (MSL 3) requirements for surface-mount assembly processes. Check for obsolescence notices or product change notifications regarding manufacturing site transfers.

Selection Notes

Select this component when a 256K x 16 organization is required with 10 ns speed performance. Ensure the design accommodates the 3.3 V supply rail and 200 mA peak current draw. Compare against other series members like the 71V416L10PHGI if lower power consumption is prioritized over the S-series specifications.

Part Context

This part belongs to the Renesas 71V416S/L family of CMOS SRAMs. The 'S' designation typically indicates specific performance or packaging variations within the broader 71V416 line, which includes variants with different access times such as 12 ns and 15 ns options.

Replacement Considerations

IDT71V416S10PHGI is a documented alias for this component. Other compatible alternatives within the same family include the 71V416L10PHGI and 71V416S12PHGI, provided timing and power constraints are met.
