7025S25PF8

Memory IC Overview

The Renesas Electronics Corporation 7025S25PF8 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 provides an access time of 25 nanoseconds and operates on a parallel interface. It requires a single power supply voltage ranging from 4.5V to 5.5V. The device is housed in a 100-pin Thin Quad Flat Package (TQFP) with dimensions of 14x14 mm. It supports surface mount installation and functions within a commercial operating temperature range of 0°C to 70°C.

Memory IC Feature Summary

• Supports simultaneous independent reads and writes at both ports without conflict
• Includes on-chip hardware semaphore signaling for port arbitration
• Features automatic power-down mode controlled by chip enable signals
• Provides separate upper-byte and lower-byte control for bus compatibility

Memory IC Applications

• Master/slave dual-port RAM configurations for 32-bit systems
• High-speed data buffering in telecommunications equipment
• Cache memory applications requiring concurrent access
• Industrial control systems needing reliable volatile storage

Memory IC Procurement Notes

This component is officially discontinued and no longer manufactured by Renesas Electronics. Verification of availability should focus on surplus distributors or secondary markets rather than direct manufacturer channels. Buyers must confirm the authenticity of existing stock due to potential obsolescence risks. Replacement planning should prioritize the recommended upgrade path to ensure long-term supply chain stability and technical support continuity.

Memory IC Selection Notes

Engineers selecting this part should note its discontinuation status and evaluate the 7025L series as the designated upgrade path. The replacement devices offer improved performance metrics such as faster access times while maintaining pin compatibility. Design reviews must account for the transition from the S-series to the L-series specifications. Verify that the target application can accommodate any minor differences in electrical characteristics between the legacy and new components.

Memory IC Part Context

The 7025S25PF8 belongs to the IDT 7025 family of dual-port SRAMs, originally developed by Integrated Device Technology before its acquisition by Renesas. This family is designed for applications requiring high-speed, non-blocking memory access. The 'S' suffix typically denotes specific speed grades and package variations within the broader 7025 product line. These devices are widely recognized for their robust arbitration logic and low standby power consumption capabilities.

Memory IC Replacement Considerations

The official upgrade substitute is the 7025L20PFGI. This component offers enhanced performance specifications compared to the discontinued 7025S25PF8. Engineers should verify pinout compatibility and electrical parameter alignment during the migration process.
