7134SA45JI

Overview

The Renesas Electronics Corporation 7134SA45JI is a dual-port static random access memory (SRAM) integrated circuit. It provides a storage capacity of 32 kilobits, organized as 4K words by 8 bits. The device features an asynchronous parallel interface with a maximum access time of 45 nanoseconds. It operates within a supply voltage range of 4.5 volts to 5.5 volts and is housed in a 52-lead Plastic Leadless Chip Carrier (PLCC) package.

Feature Summary

• Supports simultaneous independent read and write operations at both Port A and Port B for concurrent data processing.
• Utilizes asynchronous control logic to simplify system integration without requiring external clock synchronization.
• Provides high-speed data transfer capabilities suitable for demanding real-time embedded applications.

Applications

• Network router buffer memory management
• Industrial automation controller data logging
• Telecommunications equipment signal processing

Procurement Notes

Verify component authenticity through authorized channels due to end-of-life status. Confirm RoHS compliance requirements as the device may not meet current environmental standards. Validate pin compatibility with existing PCB layouts before procurement. Check for available replacement alternatives from the manufacturer's portfolio.

Selection Notes

Select this component when dual-port functionality is required for separate processor domains. Ensure the 52-pin PLCC package fits the designated footprint. Verify that the 45 ns speed meets the system timing constraints. Consider power consumption levels relative to the thermal design of the enclosure.

Part Context

This part belongs to the 7134SA series of dual-port SRAMs manufactured by Renesas Electronics. The series offers various speed grades and packaging options to accommodate different performance and form factor requirements in industrial and commercial electronic systems.

Replacement Considerations

Consult official datasheets for cross-reference models such as IDT7134SA45JI. Verify electrical parameter equivalence including voltage ranges and access times before substitution.
