7025L15JG

Memory IC Overview

The Renesas Electronics Corporation 7025L15JG is a dual-port static random-access memory (SRAM) integrated circuit with a storage capacity of 128 kilobits, organized as 8K words by 16 bits. It features asynchronous parallel interface operation with a maximum access time of 15 nanoseconds. The device operates on a single 5V power supply within a voltage range of 4.5V to 5.5V and supports an industrial temperature range from 0°C to 70°C. It is housed in an 84-pin Plastic Leadless Chip Carrier (PLCC) package measuring 29.31mm x 29.31mm.

Memory IC Feature Summary

• True dual-ported 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.
• Automatic power-down feature controlled by chip enable signals to minimize standby power consumption.
• TTL-compatible inputs and outputs allowing direct interfacing with standard digital logic systems.

Memory IC Applications

• Stand-alone high-speed dual-port memory modules in embedded systems.
• Master/Slave dual-port RAM configurations for expanding data bus widths to 32 bits or more.
• Buffering applications requiring low-latency data transfer between asynchronous system components.
• Industrial control systems operating within the specified commercial temperature range.

Memory IC Procurement Notes

Verify component authenticity through authorized distributors due to end-of-life status. Confirm RoHS3 compliance and moisture sensitivity level (MSL 3) requirements for surface-mount assembly processes. Check for specific suffix variations that may indicate packaging differences or label changes documented in official product change notices.

Memory IC Selection Notes

Select this component when true dual-port independence is required for concurrent data access. Ensure the design accommodates the 84-pin PLCC footprint and 5V logic levels. Consider alternative packages like TQFP if higher pin density or different thermal characteristics are needed for the target application environment.

Memory IC Part Context

The 7025 series represents a family of high-speed dual-port SRAMs designed for versatile memory expansion and buffering roles. The 7025L15JG specifically denotes the 15ns speed grade within the L-series, offering a balance of performance and power efficiency for general-purpose industrial and commercial electronic designs requiring reliable non-volatile-like data retention during active operation.
