7025S55GB

Memory IC Overview

The Renesas Electronics Corporation 7025S55GB is a high-speed, 128-kbit Dual-Port Static Random Access Memory (SRAM) organized as 8K words by 16 bits. It features asynchronous parallel interface operation with a maximum access time of 55 nanoseconds. The device operates on a single 5V power supply within a voltage range of 4.5V to 5.5V and utilizes an 84-pin Ceramic Pin Grid Array (CPGA) package.

Memory IC Feature Summary

• True dual-port architecture enabling simultaneous independent reads and writes from either port without bus contention
• Integrated hardware semaphore signaling for automatic port arbitration and conflict resolution
• Automatic power-down mode controlled by chip enable signals to minimize standby current consumption
• TTL-compatible inputs and outputs ensuring direct interfacing with standard logic families

Memory IC Applications

• High-performance data buffering in telecommunications equipment
• Cache memory implementation in industrial control systems
• Data storage in military-grade avionics and defense applications
• Master/slave dual-port configurations for 32-bit or wider system expansion

Memory IC Procurement Notes

Verify component authenticity through authorized distributors due to the presence of legacy IDT branding aliases. Confirm RoHS compliance status as the part may not meet current environmental directives. Validate package integrity upon receipt, as ceramic packages require careful handling to prevent mechanical stress damage during installation.

Memory IC Selection Notes

Select this component when simultaneous bidirectional data access is required without external arbitration logic. Ensure the design accommodates the specific 84-pin CPGA footprint and thermal requirements. Verify that the 55ns speed meets system timing constraints and that the operating temperature range aligns with the intended application environment.

Memory IC Part Context

This device belongs to the Renesas 7025 family of dual-port SRAMs, originally developed under Integrated Device Technology (IDT). The series provides scalable memory solutions for complex embedded systems requiring high throughput and low latency. The 7025S55GB represents the 55ns speed grade variant within the commercial and industrial temperature specifications.
