7133LA20J8

Overview

The Renesas Electronics Corporation 7133LA20J8 is a dual-port 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 an asynchronous parallel interface with a maximum access time of 20 nanoseconds and a write cycle time of 20 nanoseconds. It operates within a supply voltage range of 4.5 volts to 5.5 volts. The component is housed in a 68-pin Plastic Leadless Chip Carrier (PLCC) package designed for surface-mount technology. It supports commercial operating temperatures ranging from 0°C to +70°C.

Feature Summary

• Dual-port architecture enabling independent simultaneous access by two processors
• Asynchronous operation without requiring external clock signals
• CMOS technology ensuring low power consumption during standby and active modes

Applications

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

Procurement Notes

Verify the specific suffix J8 against official Renesas documentation to confirm pinout compatibility and package dimensions. Confirm RoHS compliance status as historical batches may differ. Check current product lifecycle status, as this part number may be discontinued or subject to design changes. Ensure the supplier provides valid traceability documents for vintage semiconductor components.

Selection Notes

Select this component when a system requires independent read/write ports for concurrent processor access. The 20ns speed suits moderate-frequency asynchronous buses. Verify that the 68-pin PLCC footprint matches the printed circuit board layout. Consider thermal management requirements within the specified commercial temperature range.

Part Context

This device belongs to the Renesas 7133LA series of dual-port SRAMs. It shares architectural similarities with other members like the 7133SA20G but differs in package type and operating temperature specifications. The series is designed for applications requiring high-bandwidth memory sharing between multiple masters.

Replacement Considerations

Official substitutes include the 7133SA20G, which offers identical electrical performance but utilizes a PGA-68 through-hole package. Verify mechanical fit and soldering process compatibility before substitution.
