7133LA25JI

Overview

The Renesas Electronics Corporation 7133LA25JI is a dual-port static random-access memory (SRAM) integrated circuit. It features a storage capacity of 32 kilobits organized as 2K words by 16 bits. The device utilizes an asynchronous parallel interface with a maximum access time of 25 nanoseconds. It operates within a supply voltage range of 4.5 volts to 5.5 volts and supports surface-mount installation in a 68-pin Plastic Leadless Chip Carrier (PLCC) package. The component is rated for an industrial operating temperature range from -40°C to +85°C.

Feature Summary

• Dual-port architecture enabling independent simultaneous read/write operations on separate ports
• Asynchronous operation allowing flexible timing control without external clock synchronization
• Industrial-grade thermal stability supporting reliable performance across extended temperature ranges

Applications

• High-speed data buffering in telecommunications equipment
• Cache memory implementation in embedded processing systems
• Data logging applications requiring rapid write access

Procurement Notes

Verify the specific suffix designation against official manufacturer documentation, as variations may indicate differences in packaging or environmental compliance. Confirm that the selected variant matches the required lead-free status if RoHS compliance is mandatory for the assembly process. Cross-reference the part number with current discontinuation notices to ensure long-term availability support.

Selection Notes

Select this component when a design requires independent dual-port access for concurrent data handling between two distinct system buses. Ensure the printed circuit board layout accommodates the 68-PLCC footprint dimensions. Validate that the power supply network can sustain the specified voltage limits while managing the peak current consumption typical of high-speed CMOS SRAM devices during active switching cycles.

Part Context

This device belongs to the 7133LA series of dual-port SRAMs manufactured by Renesas Electronics. The series provides scalable memory solutions for complex digital signal processing tasks. The LA designation typically indicates industrial temperature rating and specific pinout compatibility within the family. These components are designed to replace legacy parts in established industrial and communication hardware architectures.

Replacement Considerations

Publicly confirmed substitute part numbers include 7133SA25JGI and 7133LA25PFGI. Verify pin-to-pin compatibility and electrical parameter alignment before substitution.
