7133LA55JI

Overview

The Renesas Electronics Corporation 7133LA55JI is a dual-port static random-access memory (SRAM) integrated circuit. It provides a storage capacity of 32 kilobits, organized as 2048 words by 8 bits. The device features asynchronous parallel interface with a maximum access time of 55 nanoseconds. It operates within a supply voltage range of 4.5 volts to 5.5 volts and supports surface-mount installation in a 68-pin plastic leaded chip carrier package.

Feature Summary

• Dual-port architecture enabling independent simultaneous read/write operations on separate ports
• Asynchronous operation for flexible system integration without clock synchronization requirements
• CMOS technology ensuring low power consumption during active and standby modes

Applications

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

Procurement Notes

Verify component authenticity through authorized channels due to end-of-life status. Confirm package integrity and pin compatibility before integration. Check RoHS compliance documentation as the standard variant may not meet current environmental regulations. Validate operating temperature range suitability for specific deployment environments.

Selection Notes

Select this component when dual-port functionality is required for concurrent master-slave or peer-to-peer memory access. Ensure system voltage aligns with the 4.5V to 5.5V specification. Consider the 55ns access speed against application latency requirements. Verify physical footprint constraints match the 68-PLCC package dimensions.
