7133LA90J8

Overview

The Renesas Electronics Corporation 7133LA90J8 is a dual-port, asynchronous static random-access memory (SRAM) integrated circuit. It provides a total storage capacity of 32 kilobits, organized as 2K words by 16 bits. The device features a parallel interface with a maximum access time of 90 nanoseconds. It operates within a supply voltage range of 4.5V to 5.5V and supports an industrial temperature range of -55°C to 125°C. The component is housed in a 68-pin Plastic Leadless Chip Carrier (PLCC) package measuring 24.21mm x 24.21mm.

Feature Summary

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

Applications

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

Procurement Notes

Verify the specific suffix J8 to confirm the 68-PLCC package configuration and lead-free status. Confirm compliance with RoHS3 directives for current production batches. Check for End-of-Life notices or Product Change Notifications regarding assembly site changes. Ensure compatibility with existing board layouts requiring the 68-PLCC footprint.

Selection Notes

Select this component when dual-port functionality is required for concurrent data handling. The 90ns speed suits moderate-speed asynchronous interfaces. The wide operating temperature range supports harsh industrial environments. Verify that the 2Kx16 organization matches the system memory map requirements.

Part Context

This part belongs to the 7133 series of dual-port SRAMs from Renesas. It shares architectural similarities with other variants like the 7133SA and 7133LA families, differing primarily in speed grades and package options. The LA suffix typically denotes extended temperature ranges compared to standard SA counterparts.
