7025S35PF

Memory IC Overview

The Renesas Electronics Corporation 7025S35PF is a dual-port static random-access memory (SRAM) integrated circuit. It features a storage capacity of 128 kilobits organized as 8K words by 16 bits. The device utilizes parallel interface technology with an access time and write cycle time of 35 nanoseconds. It operates on a single 4.5V to 5.5V power supply and supports surface-mount installation in a 100-pin Thin Quad Flat Package measuring 14x14 millimeters. The component functions asynchronously and is designed for industrial temperature ranges.

Memory IC Feature Summary

• Supports simultaneous independent reads and writes from two separate ports without conflict
• Includes on-chip hardware semaphore signaling for port arbitration and interrupt flags
• Features automatic power-down mode controlled by chip enable signals for low standby consumption

Memory IC Applications

• High-speed data buffering in telecommunications equipment
• Cache memory implementation in embedded processing systems
• Data logging applications requiring rapid concurrent access
• Industrial control systems needing reliable volatile storage

Memory IC Procurement Notes

Verify the specific package suffix and temperature grade against current datasheets, as variations exist within the 7025 family. Confirm RoHS compliance status prior to integration, as older batches may not meet modern environmental standards. Check for active discontinuation notices or end-of-life notifications from the manufacturer to ensure long-term supply chain stability for production runs.

Memory IC Selection Notes

Select this component when asynchronous dual-port architecture is required for shared memory resources between processors. Ensure the design accommodates the 100-pin TQFP footprint and 5V logic levels. Consider alternative packages like PGA if through-hole mounting is necessary, or verify if faster access times are needed for higher performance requirements beyond the 35ns specification.

Memory IC Part Context

This part belongs to the Renesas 7025 series of high-speed dual-port SRAMs. The series offers various access speeds and packaging options to suit different system constraints. The 7025S35PF specifically targets applications requiring moderate speed with a compact surface-mount form factor, providing a balance between performance and board space efficiency for complex digital designs.
