7133LA55J

Memory IC Overview

The Renesas Electronics Corporation 7133LA55J is a dual-port, asynchronous static random-access memory (SRAM) integrated circuit. It provides a storage capacity of 32 kilobits organized as 2K words by 16 bits. The device features a parallel interface with a maximum access time and write cycle time of 55 nanoseconds. It operates within a supply voltage range of 4.5V to 5.5V and supports surface-mount installation in a 68-lead Plastic Leadless Chip Carrier (PLCC) package measuring 24.21mm x 24.21mm. The component is rated for an operating temperature range of 0°C to 70°C.

Memory IC Feature Summary

Supports independent simultaneous read/write operations on both ports without conflict.
Utilizes CMOS technology for high-speed asynchronous data transfer.
Features a standard parallel interface compatible with legacy system architectures.

Memory IC Applications

High-speed data buffering in telecommunications equipment
Cache memory implementation in industrial control systems
Data storage in embedded network processing units

Memory IC Procurement Notes

Verify the specific suffix J indicates the PLCC package variant when sourcing replacements. Confirm RoHS compliance status as older batches may not meet current environmental directives. Check manufacturer end-of-life notices for availability constraints. Ensure voltage levels match the 4.5V to 5.5V requirement before integration.

Memory IC Selection Notes

Select this component when dual-port independence is required for concurrent processor access. Compare against single-port alternatives if only one master device accesses the memory. Consider the 55ns speed grade relative to system clock requirements. Evaluate the PLCC footprint against available printed circuit board real estate.

Memory IC Part Context

This part belongs to the 7133SA/LA series of dual-port SRAMs from Renesas. It shares functional similarities with the 7133SA55G but differs in package type and commercial temperature rating. The LA suffix typically denotes extended or specific commercial variants within the broader family architecture.
