7025S35PFGI

Memory IC Overview

The Renesas Electronics Corporation 7025S35PFGI is a high-speed, asynchronous dual-port static random-access memory (SRAM) device. It features a storage capacity of 128 kilobits organized as 8K words by 16 bits. The component operates with a maximum access time and write cycle time of 35 nanoseconds. It requires a single 5-volt power supply within a range of 4.5 to 5.5 volts. The device is housed in a 100-pin Thin Quad Flat Package measuring 14x14 millimeters. It supports an industrial operating temperature range from -40°C to +85°C.

Memory IC Feature Summary

• True dual-port architecture enables simultaneous independent reads and writes from either port without conflict.
• On-chip hardware support for semaphore signaling facilitates efficient data synchronization between ports.
• Separate upper-byte and lower-byte control lines allow compatibility with multiplexed bus systems.
• Automatic power-down mode controlled by chip enable signals reduces standby power consumption.

Memory IC Applications

• High-speed data buffering in telecommunications equipment
• Cache memory implementation in embedded processing systems
• Master/slave configurations for expanding data bus widths beyond 16 bits
• Real-time signal processing applications requiring low-latency access

Memory IC Procurement Notes

Verify the specific suffix requirements against current manufacturer documentation, as package and temperature variants may differ. Confirm RoHS compliance status prior to integration, as older revisions may not meet current environmental directives. Check for active obsolescence notices or end-of-life declarations before finalizing procurement plans. Ensure that the selected variant matches the required thermal grade for the intended operational environment.

Memory IC Selection Notes

Select this component when simultaneous bidirectional data access is required without external arbitration logic. Choose the 35-nanosecond speed grade for applications demanding moderate throughput with low power consumption. Verify that the 100-pin TQFP footprint fits the available board space constraints. Consider the industrial temperature rating if the deployment environment experiences significant thermal fluctuations.

Memory IC Part Context

This part belongs to the Renesas 7025 series of dual-port SRAMs, designed for standalone or cascaded memory systems. The series provides TTL-compatible interfaces and supports battery backup operations for data retention. It is engineered to eliminate the need for discrete logic in multi-port memory expansions, simplifying system design and reducing component count.
