71342LA25J8

Overview

The 71342LA25J8 is a 32Kb (4K x 8) dual-port static random-access memory manufactured by Renesas Electronics. It utilizes asynchronous parallel interface technology and operates within a supply voltage range of 4.5V to 5.5V. The component features a 25ns access time and a 25ns write cycle time. It is housed in a 52-PLCC surface-mount package with J-leads, designed for commercial temperature environments ranging from 0°C to +70°C.

Feature Summary

• Dual-port architecture enabling independent simultaneous access by two processors
• Asynchronous operation without requiring a system clock signal
• CMOS technology providing low power consumption characteristics

Applications

• High-speed data buffering between processing units
• Cache memory implementation in embedded systems
• Data storage in telecommunications equipment

Procurement Notes

This component is officially designated as obsolete by the manufacturer. Availability is restricted to surplus or secondary market channels. Verify RoHS compliance status carefully, as original specifications may not meet current environmental directives. Confirm lot dates and physical integrity upon receipt due to long-term storage conditions.

Selection Notes

Select this part only if legacy compatibility with 5V logic levels and PLCC footprints is required. Evaluate alternative modern SRAMs for improved power efficiency and smaller form factors. Ensure design margins accommodate the specified commercial temperature range and verify that the 25ns speed meets system timing requirements.

Part Context

Part of the 71342LA series of dual-port SRAMs. This specific model represents an older generation CMOS memory solution. It shares architectural similarities with other variants in the family but differs in speed grade and packaging options. The device was widely used before the industry transitioned to lower voltage standards.
