7132LA100J8

Memory IC Overview

The Renesas Electronics Corporation 7132LA100J8 is a dual-port static random-access memory (SRAM) integrated circuit with an 8-bit bus width and a total density of 16 kilobits, organized as 2k x 8. It features an asynchronous interface with a maximum access time of 100 nanoseconds. The device operates on a single 5.0 V TTL supply voltage within a temperature range of 0 to 70 degrees Celsius. It is housed in a 52-pin Plastic Leadless Chip Carrier (PLCC) package measuring 19.0 mm by 19.0 mm with a pitch of 1.27 mm. The component includes busy and slave I/O functions for port control.

Memory IC Feature Summary

• Supports simultaneous independent read and write operations at two distinct ports via dedicated address, data, and control lines.
• Integrates hardware-based busy flag signaling to indicate active internal write cycles without requiring software polling.
• Provides dedicated slave port control logic to manage arbitration and prevent bus contention during concurrent access.

Memory IC Applications

• High-speed data buffering between microprocessors and peripheral devices
• FIFO buffer implementations in communication interfaces
• Cache memory subsystems in embedded processing systems

Memory IC Procurement Notes

Verify the specific suffix J8 against official datasheets to confirm pinout compatibility and lead-free status. Confirm moisture sensitivity level handling requirements prior to soldering. Check current lifecycle status as this component may be discontinued or subject to last-time buy restrictions. Ensure voltage levels match system design specifications before integration.

Memory IC Selection Notes

Select this component when dual-port functionality is required for concurrent master-slave architecture. Verify that the 100 ns access time meets system timing constraints. Ensure the PLCC-52 package fits the available PCB footprint. Confirm that the 5V logic level aligns with the host processor's I/O standards.

Memory IC Part Context

This part belongs to the Renesas 7132/7142 series of dual-port SRAMs. These components are designed for applications requiring high-speed data sharing between two independent processors or buses. The series offers various access speeds and densities to suit different performance requirements in industrial and commercial electronics.

Memory IC Replacement Considerations

Consult official substitution guides for compatible parts such as the IDT7132LA100J8. Verify electrical parameters and pin compatibility before replacement. Ensure the substitute part supports the same dual-port architecture and voltage requirements.
