7133SA20J8

Overview

The Renesas Electronics Corporation 7133SA20J8 is an asynchronous dual-port static random-access memory (SRAM) integrated circuit. It provides a storage capacity of 32 kbit, organized as 2k x 16 bits. The device features a parallel interface with a maximum access time of 20 ns. It operates within a supply voltage range of 4.5 V to 5.5 V and supports surface-mount installation in a PLCC-52 package.

Feature Summary

• Dual-port architecture enabling independent simultaneous access by two processors
• CMOS technology for low power consumption
• Asynchronous operation mode

Applications

• High-speed data buffering between processors
• Cache memory applications
• FIFO buffer implementations

Procurement Notes

Verify component authenticity through authorized channels due to obsolete status. Confirm RoHS compliance requirements against the specific manufacturing date code, as older batches may not meet current environmental standards. Validate package integrity upon receipt to ensure pin alignment matches the PLCC-52 specification before soldering.

Selection Notes

Select this component when dual-port functionality is required for 16-bit wide data paths. Ensure the design accommodates the 20 ns access speed and 5V logic levels. Verify that the PLCC-52 footprint fits the PCB layout constraints compared to alternative packages like TQFP or PGA.

Part Context

This part belongs to the 7133SA series of dual-port SRAMs from Renesas. It shares architectural similarities with other members of the family but differs in organization and package type. The 'J' suffix typically denotes a specific temperature range or package variant within the product line.
