70261L35PFI8

Memory IC Overview

The Renesas Electronics Corporation 70261L35PFI8 is a dual-port asynchronous static random-access memory (SRAM) integrated circuit. It provides a total storage capacity of 256 kbit, organized as 16k words by 16 bits per word. The device features a parallel interface with a maximum access time of 35 ns. It operates within a supply voltage range of 4.5 V to 5.5 V and supports surface-mount installation in a 100-TQFP package measuring 14x14 mm. The component is rated for an industrial operating temperature range from -40°C to +85°C.

Memory IC Feature Summary

• Dual-port architecture enabling independent simultaneous read/write operations on separate ports
• Asynchronous operation without requiring a system clock signal
• Parallel data interface for direct connection to microprocessors or controllers

Memory IC Applications

• High-speed data buffering in telecommunications equipment
• Cache memory implementation in embedded systems
• Data acquisition systems requiring rapid temporary storage

Memory IC Procurement Notes

Verify the specific suffix configuration against official datasheets to ensure compatibility with existing board designs. Confirm RoHS compliance status and moisture sensitivity level requirements prior to procurement. Check current availability as this component may be subject to discontinuation notices or limited stock constraints from authorized distributors.

Memory IC Selection Notes

Select this component when dual-port functionality is required for concurrent processor access. Ensure the design accommodates the 4.5 V to 5.5 V supply voltage requirement. Verify that the 100-TQFP footprint matches the PCB layout. Consider thermal management capabilities within the specified industrial temperature range during system integration.

Memory IC Part Context

This part belongs to the Renesas 70261 series of dual-port SRAMs. It shares architectural similarities with other members like the 70261S35PFI8 but differs in package type and specific electrical characteristics. The series is designed for applications requiring high-speed, non-volatile-like performance with true dual-port independence.

Memory IC Replacement Considerations

Official upgrade alternatives include the 70261L20PFGI8. Verify pinout compatibility and electrical parameter alignment before substitution.
