7025S12PF

Memory IC Overview

The Renesas Electronics Corporation 7025S12PF is a high-speed, asynchronous dual-port static random-access memory (SRAM) IC. It provides a storage capacity of 128K bits, organized as 8K words by 16 bits. The device features parallel interface access with a maximum access time of 12 ns. It operates on a single 5V power supply within the voltage range of 4.5V to 5.5V. The component is housed in a 100-pin Thin Quad Flat Package (TQFP) with dimensions of 14x14 mm. It supports surface mount installation and includes hardware support for semaphore signaling and port arbitration.

Memory IC Feature Summary

• True dual-ported memory architecture enabling simultaneous independent reads from both ports.
• On-chip hardware support for semaphore signaling and automatic port arbitration logic.
• Separate upper-byte and lower-byte control lines designed for multiplexed bus compatibility.
• Automatic power-down feature controlled by Chip Enable signals for low standby power consumption.

Memory IC Applications

• Stand-alone 128K-bit dual-port RAM systems
• Master/Slave dual-port configurations for 32-bit or wider data bus expansion
• High-speed data buffering in network equipment
• Real-time processing applications requiring concurrent port access

Memory IC Procurement Notes

Verify component authenticity through authorized distributors due to potential counterfeit risks. Confirm RoHS compliance status as older variants may not meet current environmental standards. Check for moisture sensitivity level handling requirements during storage and assembly. Ensure the specific suffix matches the required package type and temperature rating. Validate lead availability as production status may vary.

Memory IC Selection Notes

Select this component when simultaneous independent access to shared memory is required without external arbitration overhead. Choose the 12 ns speed grade for high-frequency applications needing faster access than standard 20 ns variants. Consider the 100-TQFP package for dense surface-mount layouts. Evaluate power consumption needs against the automatic power-down capabilities provided by the Chip Enable inputs.

Memory IC Part Context
