7025L45PFI8

Memory IC Overview

The Renesas Electronics Corporation 7025L45PFI8 is a dual-port static random-access memory (SRAM) integrated circuit. It features a storage capacity of 128 kilobits organized as 8K words by 16 bits. The device utilizes asynchronous parallel interface technology with a maximum access time of 45 nanoseconds. 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 Flatpack (TQFP) package measuring 14x14 mm, designed for surface-mount installation. It supports an industrial operating temperature range from -40°C to +85°C.

Memory IC Feature Summary

• True dual-ported memory architecture enabling simultaneous independent reads and writes from two separate ports without conflict.
• On-chip hardware support for semaphore signaling and port arbitration logic to manage data integrity between ports.
• Separate upper-byte and lower-byte control lines providing compatibility with multiplexed bus systems.
• Master/Slave select capability allowing multiple devices to be cascaded to expand data bus width beyond 16 bits.

Memory IC Applications

• High-speed data buffering in telecommunications equipment requiring low-latency memory access.
• Network switching applications utilizing dual-port functionality for packet processing and forwarding.
• Industrial control systems operating within extended temperature ranges requiring reliable volatile memory.
• Embedded systems needing expanded data bus architectures through cascaded SRAM configurations.

Memory IC Procurement Notes

Verify component authenticity and physical condition upon receipt, as this part may be subject to end-of-life status or limited availability. Confirm that the specific suffix matches the required lead-free or tin-lead finish specifications for your assembly process. Ensure proper handling procedures are followed due to moisture sensitivity classification. Cross-reference datasheet revisions to confirm pinout and electrical characteristics remain consistent with design requirements before finalizing procurement orders.

Memory IC Selection Notes

Select this component when a system requires true dual-port memory capabilities with asynchronous operation and 16-bit word width. The 45ns access speed suits applications where moderate latency is acceptable but simultaneous multi-port access is critical. Consider the 100-pin TQFP package constraints regarding PCB space and thermal management. Evaluate the need for on-chip arbitration features if direct port-to-port communication is required without external microcontroller intervention.

Memory IC Part Context

The 7025 series represents a family of high-speed dual-port SRAMs manufactured by Renesas Electronics, formerly IDT. This specific model belongs to the industrial grade subset, distinguished by its wider operating temperature range compared to commercial variants. The 'L' designation typically indicates low-power consumption characteristics relative to older 'S' series counterparts, while the 'PFI8' suffix defines the package type and termination finish.

Memory IC Replacement Considerations

Public confirmed substitute part numbers include 7025L20PFGI8 and 7025L20JGI8. These alternatives offer faster access times of 20ns. Verify pin compatibility and package dimensions before substitution, as changes in access speed may require timing adjustments in the host system design.
