70261S20PF

Memory IC Overview

The Renesas 70261S20PF is a dual-port asynchronous static random-access memory (SRAM) IC with a total density of 256 Kbit. The memory organization is structured as 16K words by 16 bits per port. It features a parallel interface and supports a maximum access time of 20 ns. The device operates on a single 5 V power supply. It is housed in a 100-pin Thin Quad Flat Package (TQFP) with dimensions of 14x14 mm, suitable for surface-mount technology applications.

Memory IC Feature Summary

• Dual-port architecture enabling independent simultaneous access to the same memory array from two separate ports.

Memory IC Applications

• High-speed data buffering in telecommunications equipment
• Cache memory implementation in embedded processing systems
• Data storage in industrial control networks requiring concurrent read/write operations

Memory IC Procurement Notes

Verify the specific suffix 'PF' against the manufacturer's current datasheet to confirm package type and lead-free status. Ensure compatibility with 5V logic levels and check for moisture sensitivity classification prior to soldering. Confirm that the 20 ns access speed meets system timing requirements.

Memory IC Selection Notes

Select this component when a system requires true dual-port functionality for concurrent data handling without external arbitration. Compare against single-port alternatives if only one master is present. Verify that the 100-pin TQFP footprint fits the PCB layout constraints and that the 5V voltage tolerance aligns with the host processor I/O standards.

Memory IC Part Context

This part belongs to the Renesas 70261 series of high-performance dual-port SRAMs. These devices are designed to replace FIFOs or complex shared-memory interfaces in applications demanding low latency and high throughput. The series typically includes variants with different access speeds and organizational structures.

Memory IC Replacement Considerations

Check for direct pin-compatible replacements within the 70261 family, such as the 70261S25PF, which offers a slower 25 ns access time but maintains the same package and electrical characteristics.
