Overview
The 71V424L10PHG8 is a 4 Mbit (512K x 8) asynchronous static random-access memory manufactured by Renesas Electronics. It operates within a supply voltage range of 3 V to 3.6 V and features a maximum access time of 10 ns. The device utilizes a parallel interface and is housed in a 44-TSOP II package with dimensions of 0.400 inches (10.16 mm) width. It supports surface-mount installation and functions reliably across an operating temperature range of 0°C to +70°C.
Feature Summary
- Asynchronous SRAM architecture providing 4 Mbit storage capacity organized as 512K words by 8 bits.
- High-speed data access capability with a maximum access time of 10 ns for efficient system integration.
- Operates on a single 3.3 V CMOS power supply, ensuring compatibility with standard logic levels.
Applications
- Data buffering in high-speed digital signal processing systems
- Cache memory implementation in embedded controllers
- Temporary storage in industrial automation equipment
Procurement Notes
Verify the specific suffix PHG8 to confirm the 44-TSOP II package type and commercial temperature rating. Confirm RoHS compliance status through official documentation prior to assembly. Check for end-of-life notifications or product discontinuance notices from Renesas to ensure long-term availability for production planning.
Selection Notes
Select this component when a 512K x 8 organization is required with 10 ns speed performance. Ensure the design environment stays within the 0°C to +70°C operational range. Verify that the 44-pin TSOP II footprint matches the PCB layout constraints and that the 3.3 V supply rail meets the specified voltage tolerances.
Part Context
This part belongs to the 71V424 series of asynchronous SRAMs from Renesas Electronics. The series offers various speed grades and packaging options, including SOJ and TSOP variants. The 71V424L10PHG8 specifically denotes the 10 ns speed grade in the commercial temperature range using the TSOP II package format.
Replacement Considerations
Direct substitutes include other 71V424 series parts with compatible pinouts, such as the 71V424L10PHGI or different speed grades like the 71V424L12PHG8, provided the package and electrical specifications align with the original design requirements.
