7133LA70J

Overview

The Renesas Electronics Corporation 7133LA70J is a dual-port static random-access memory (SRAM) integrated circuit with a total storage capacity of 32 kilobits. The memory organization is structured as 2K words by 16 bits, accessed via a parallel interface. This asynchronous device features a maximum access time of 70 nanoseconds and operates within a supply voltage range of 4.5 volts to 5.5 volts. It is housed in a 68-pin Plastic Leadless Chip Carrier (PLCC) package designed for surface mount installation. The component supports an industrial operating temperature range from 0°C to 70°C.

Feature Summary

• Dual-port architecture enabling independent simultaneous read and write operations on separate ports.

Applications

• High-speed data buffering in industrial control systems
• Real-time processing applications requiring concurrent data access
• Embedded memory solutions for automated machinery

Procurement Notes

Verify the current manufacturing status before procurement planning, as this component may be subject to end-of-life restrictions or discontinuation notices. Confirm that the 68-PLCC package dimensions align with existing printed circuit board footprints. Ensure compliance with RoHS directives if required by specific project standards, noting that some variants in this series may not meet current environmental regulations. Validate lead-free soldering profiles compatible with the plastic leadless chip carrier construction.

Selection Notes

Select this component when a system requires independent dual-port memory access for asynchronous data handling. The 70-nanosecond access speed suits moderate-to-high performance requirements without demanding ultra-fast cycle times. The 68-pin PLCC package offers a robust surface-mount solution suitable for environments where through-hole mounting is impractical but high pin count density is necessary. Verify power supply stability within the specified 4.5V to 5.5V range to ensure reliable operation across the full industrial temperature spectrum.

Part Context

This part belongs to the 7133LA series of dual-port SRAMs manufactured by Renesas Electronics. It shares architectural similarities with other members of the family, such as the 7133SA series, differing primarily in speed grades and packaging options. The series is designed for applications requiring reliable, non-volatile-like persistence during power cycles only while powered, serving as high-speed scratchpad memory in complex digital logic designs.

Replacement Considerations

Direct replacements must match the 32Kb capacity, 2Kx16 organization, and 68-pin PLCC package. Verify that substitute components support the same 70ns access time and 4.5V-5.5V operating voltage. Check for pinout compatibility to ensure direct socket interchangeability without PCB redesign.
