7027S35PFI

Memory IC Overview

The 7027S35PFI is a high-speed, asynchronous dual-port static random-access memory (SRAM) manufactured by Renesas Electronics Corporation. It provides a storage capacity of 512Kb organized as 32K words by 16 bits. The device features parallel interface access with a maximum access time and write cycle time of 20 ns. It operates on a single 4.5V to 5.5V power supply and supports an industrial temperature range from -40°C to +85°C. The component is housed in a 100-pin Thin Quad Flat Package (TQFP) measuring 14x14 mm.

Memory IC Feature Summary

• True dual-port architecture enables simultaneous independent read and write operations from either port without conflict.
• Integrated hardware semaphore signaling facilitates efficient data synchronization between the two ports.
• Automatic power-down mode reduces standby current consumption when chip enable signals are inactive.
• TTL-compatible logic levels allow direct interfacing with standard digital systems.

Memory IC Applications

• High-performance telecommunications equipment requiring fast data buffering
• Industrial control systems needing reliable dual-processor communication
• Network infrastructure devices utilizing packet switching and routing

Memory IC Procurement Notes

This component has reached end-of-life status and is no longer manufactured. Verify availability through authorized distributors for remaining stock or consider approved replacement parts. Ensure compliance with RoHS directives if required, as this specific part may not meet current environmental standards. Confirm package authenticity and moisture sensitivity handling procedures upon receipt.

Memory IC Selection Notes

Select this part for applications requiring true dual-port memory with 20 ns speed and 512Kb capacity. Ensure the design accommodates the 100-TQFP package dimensions and 4.5V to 5.5V voltage requirements. Consider the industrial temperature range suitability for harsh environments. Evaluate alternative components if lead times or obsolescence pose risks to production schedules.

Memory IC Part Context
