Overview
The 71V416S15YGI8 is a 4 Mbit (256K x 16) asynchronous static random-access memory manufactured by Renesas Electronics. It operates on a single 3.3 V CMOS supply with a voltage range of 3.0 V to 3.6 V. The device features a 15 ns access time and utilizes a parallel interface. It is housed in a 44-pin Small Outline J-Lead (SOJ) package designed for surface-mount installation. The component supports an operating temperature range from 0°C to +70°C and includes moisture sensitivity level 3 classification.
Feature Summary
- Fully static asynchronous circuitry requiring no clocks or refresh cycles for operation
- LVTTL-compatible bidirectional inputs and outputs for direct logic interfacing
- Center power and ground pinout configuration to reduce noise and improve signal integrity
Applications
- High-speed data buffering in embedded systems
- Cache memory implementation in industrial control units
- Data storage in telecommunications equipment
Procurement Notes
Verify the specific suffix YGI8 against official datasheets to confirm the SOJ-44 package and commercial temperature grade. Confirm RoHS compliance status as manufacturing processes may evolve. Check for End-of-Life notices or Product Change Notifications, as this component family has faced discontinuation events. Ensure compatibility with existing PCB footprints before procurement.
Selection Notes
Select this part when a 256K x 16 organization is required with 15 ns speed at 3.3 V. Compare against the PHG variant if an industrial temperature range (-40°C to +85°C) or TSOP-44 package is needed instead. Verify that the LVTTL I/O levels match the system logic requirements. Consider alternative packages if board space constraints differ from the SOJ form factor.
Part Context
This component belongs to the 71V416S series of high-speed CMOS SRAMs. It shares architectural similarities with other parts in the 71V416 family but differs in speed grade and packaging. The manufacturer transitioned from IDT to Renesas Electronics, maintaining functional compatibility within the series while updating manufacturing sites and quality standards over time.
Replacement Considerations
Official substitutes include the 71V416S15PHG and 71V416S15PHGI8, which offer identical electrical specifications but utilize a TSOP-44 package and support an extended industrial temperature range.
