7025S45PF

Memory IC Overview

The Renesas Electronics Corporation 7025S45PF is a high-speed, asynchronous dual-port static random-access memory (SRAM) device. It provides a storage capacity of 128 kilobits organized as 8K words by 16 bits. The component features independent read/write ports allowing simultaneous access to the same memory location without conflict. It operates with a maximum access time of 45 nanoseconds and requires a single 5V power supply within a 4.5V to 5.5V range. The device is housed in a 100-pin Thin Quad Flat Package (TQFP) with a 14x14 mm footprint.

Memory IC Feature Summary

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

Memory IC Applications

• Stand-alone 128K-bit dual-port memory systems
• Master/Slave dual-port configurations for 32-bit or wider data bus expansion
• Battery-backed systems requiring 2V data retention capabilities
• Industrial applications operating within the extended temperature range

Memory IC Procurement Notes

Verify RoHS compliance status carefully, as specific suffixes may indicate non-compliance. Confirm package type matches the 100-TQFP requirement. Check for lead-free alternatives if environmental regulations apply. Ensure voltage levels match the 4.5V to 5.5V specification. Validate that the 45ns access time meets system timing requirements.

Memory IC Selection Notes

Select this component when simultaneous independent access to shared memory is required. The 45ns speed suits moderate-speed asynchronous interfaces. Consider the 100-pin TQFP package for surface-mount assembly constraints. Evaluate the need for on-chip arbitration if multiple masters share the bus. Verify thermal performance for the intended operating environment.

Memory IC Part Context

The 7025 series represents a family of high-speed dual-port SRAMs designed for complex data handling. This specific model utilizes asynchronous operation for flexible interface integration. The technology supports TTL-compatible inputs and outputs. It is part of a lineage offering various access speeds and packaging options for diverse embedded memory needs.

Memory IC Replacement Considerations

The 7025L20PFGI is listed as an upgrade alternative. Verify pinout compatibility and electrical specifications before substitution. Ensure the replacement supports the required dual-port functionality and access times.
