7140LA25PF

Overview

The 7140LA25PF is a high-speed 1K x 8 Dual-Port Static RAM designed for parallel interface applications. It operates with a 25 ns access time and supports a supply voltage range of 4.5V to 5.5V. The component is housed in a 64-TQFP (14x14) surface-mount package. It functions as an asynchronous memory IC, providing independent read/write ports for simultaneous data access.

Feature Summary

Dual-port architecture enabling independent master and slave operations
High-speed asynchronous parallel interface
CMOS technology for low power consumption

Applications

Data buffering in communication systems
Cache memory in embedded processors
FIFO buffers in digital signal processing

Procurement Notes

Verify component authenticity through authorized distributors due to obsolete status. Check datasheet revisions for pinout compatibility. Confirm RoHS compliance requirements against legacy standards. Validate package dimensions against PCB footprint specifications before integration.

Selection Notes

Consider the 7130 series as a compatible master counterpart for dual-port configurations. Evaluate alternative packages if lead-free requirements are mandatory. Assess thermal performance within the specified operating temperature range. Ensure voltage levels match system logic requirements.

Part Context

Part of the Renesas 7140 family of dual-port SRAMs. Designed for high-performance data storage where simultaneous access is critical. Often paired with 7130 series devices for complete dual-port solutions.

Replacement Considerations

Check for direct replacements like 7140LA25PFGI or similar variants. Verify electrical parameters match original specifications. Review mechanical drawings for package compatibility.
