7134SA55J

Overview

The Renesas Electronics Corporation 7134SA55J is a static random-access memory (SRAM) integrated circuit featuring dual-port asynchronous architecture. It provides a storage capacity of 32 kbit organized as 4K x 8 bits. The device supports parallel interface communication with a maximum access time of 55 ns. It operates within a supply voltage range of 4.5 V to 5.5 V and draws a maximum power supply current of 240 mA. The component is designed for surface-mount installation in a 52-PLCC package and functions reliably across an operating temperature range of 0°C to +70°C.

Feature Summary

• Dual-port asynchronous SRAM architecture enabling independent simultaneous access by two masters
• CMOS technology ensuring low power consumption during operation
• Parallel interface supporting standard data bus configurations

Applications

• High-speed data buffering in embedded systems
• Cache memory implementation in microprocessor designs
• Data storage in industrial control applications

Procurement Notes

Verify component authenticity through authorized channels due to end-of-life status. Confirm RoHS compliance requirements as the part may not meet current environmental standards. Validate pin compatibility and electrical specifications against target system designs before integration. Check for available legacy stock or qualified replacement alternatives from the manufacturer.

Selection Notes

Select this component when dual-port functionality is required for concurrent master access. Ensure the design accommodates the 52-pin PLCC footprint and 4.5V to 5.5V supply constraints. Consider the 55 ns access speed relative to system clock requirements. Evaluate thermal management needs given the commercial temperature range limitations.
