71342SA35J8

Overview

The 71342SA35J8 is a dual-port static random-access memory integrated circuit manufactured by Renesas Electronics Corporation. It features a storage capacity of 32 kilobits organized as 4K words by 8 bits. The device utilizes a parallel interface and operates with an access time of 35 nanoseconds. It supports a supply voltage range from 4.5 volts to 5.5 volts. The component is housed in a 52-pin Plastic Leadless Chip Carrier package designed for surface-mount technology. It functions within an operating temperature range of 0 degrees Celsius to 70 degrees Celsius.

Feature Summary

• Supports simultaneous independent access to the same memory location from two separate ports
• Includes automatic power-down functionality controlled by chip enable signals
• Operates on a single TTL-compatible 5-volt power supply

Applications

• High-speed data buffering in communication systems
• Cache memory implementation in embedded processors
• Data logging applications requiring fast write cycles

Procurement Notes

Verify component authenticity through authorized channels due to obsolete status. Confirm package integrity upon receipt, as moisture sensitivity requires proper handling. Check datasheet revisions for any pinout or electrical specification updates prior to integration into new designs.

Selection Notes

Select this component when dual-port architecture is required for concurrent master-slave operations. Ensure system voltage aligns with the specified 4.5V to 5.5V range. Consider the PLCC-52 footprint constraints during PCB layout planning.

Part Context

This part belongs to the 71342 series of high-speed dual-port SRAMs. It serves as a slave device in multi-word width configurations alongside master dual-port RAMs. The series provides error-free operation without additional discrete logic for synchronization.

Replacement Considerations
