Overview
The Renesas Electronics 71V416S12YGI8 is a 4 Mbit (256K x 16) asynchronous static random-access memory (SRAM) IC. It operates on a single 3.3V CMOS supply with a voltage range of 3.0V to 3.6V. The device features a parallel interface and offers a maximum access time of 12 ns. It is housed in a 44-pin Small Outline J-Lead (SOJ-44) surface-mount package. The component supports an industrial operating temperature range from -40°C to +85°C and has a maximum power supply current of 180 mA.
Feature Summary
- Fully static asynchronous circuitry requiring no clocks or refresh cycles for operation
- LVTTL-compatible bidirectional inputs and outputs for direct logic interfacing
- Single 3.3V power supply operation with center power and ground pinout configuration
Applications
- Asynchronous data buffering in embedded systems
- Cache memory implementation in microcontroller-based designs
- Industrial control system data storage
Procurement Notes
This component is officially designated as End-of-Life (EOL) by the manufacturer. Distribution channels indicate restricted availability, with some suppliers reporting non-sale status in specific regions. Verification of current stock levels and alternative sourcing options is required before integration into new production plans due to the discontinued lifecycle status.
Selection Notes
Select this part for applications requiring 4 Mbit capacity with a 16-bit word width and 12 ns speed. Ensure the design accommodates the SOJ-44 package dimensions and 3.3V logic levels. Verify that the host system can support the specified 180 mA peak current draw and operates within the -40°C to +85°C temperature range.
Part Context
The 71V416S12YGI8 belongs to the Renesas 71V416S series of high-speed SRAMs. This series provides non-volatile-like performance without the complexity of flash programming. The 'S' suffix typically denotes the SOJ package variant, while '12' indicates the 12 ns access speed class within the product family.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Due to the EOL status, engineers should consult official Renesas replacement guides or evaluate equivalent 256Kx16 12ns SOJ-44 SRAMs from other manufacturers.
