70261S12PF8

Memory IC Overview

The Renesas Electronics Corporation 70261S12PF8 is a dual-port static random-access memory (SRAM) integrated circuit. It provides a storage capacity of 256 Kbit, organized as 16K words by 16 bits. The device features an asynchronous parallel interface with a maximum access time of 12 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 classified as volatile memory technology.

Memory IC Feature Summary

• Dual-port architecture enabling independent simultaneous read/write operations on both ports
• Asynchronous operation without requiring a system clock signal for data transfer
• Parallel interface supporting standard logic levels for direct microprocessor connection

Memory IC Applications

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

Memory IC Procurement Notes

Verify the specific suffix requirements for packaging and environmental compliance before ordering. Confirm that the 100-TQFP footprint matches the target PCB design. Check current lifecycle status as this part may be subject to discontinuation notices. Ensure supply chain sources provide valid traceability documentation for quality assurance purposes.

Memory IC Selection Notes

Select this component when dual-port functionality is required for concurrent data handling. The 12 ns speed suits applications needing fast asynchronous access. Compare against single-port alternatives if only one port is utilized. Consider the 100-pin package density for board space constraints relative to lower pin-count memories.

Memory IC Part Context

This device belongs to the 70261 series of high-performance SRAMs manufactured by Renesas Electronics. The series offers various access speeds and packaging options to accommodate different system timing requirements. The 70261S12 variant specifically targets applications demanding faster cycle times compared to slower members of the family.

Memory IC Replacement Considerations

Publicly documented upgrades include the 70261L12PFG8. Verify pin compatibility and electrical specifications before substitution.
