71342SA70J8

Memory IC Overview

The Renesas Electronics Corporation 71342SA70J8 is a high-speed, asynchronous dual-port static random-access memory (SRAM) device. It features a storage capacity of 32 kilobits organized as 4K words by 8 bits per word. The component operates with a maximum access time of 70 nanoseconds and supports parallel interface communication. It requires a single TTL-compatible 5V power supply operating within a voltage range of 4.5V to 5.5V. The device is housed in a 52-pin Plastic Leadless Chip Carrier (PLCC) package designed for surface mount installation.

Memory IC Feature Summary

Provides fully independent dual ports allowing simultaneous read and write operations to the same memory location without conflict.
Integrates on-chip hardware semaphore logic to facilitate automatic arbitration and signaling between the two ports.
Supports battery backup operation to maintain data retention at low voltages.

Memory IC Applications

High-performance real-time industrial control systems requiring concurrent data access
Telecommunications equipment utilizing shared memory buffers
Automotive electronic control units needing reliable volatile storage

Memory IC Procurement Notes

Verify component authenticity through authorized channels due to obsolete status. Confirm package integrity and pin alignment against the 52-PLCC specification. Check datasheet revisions for any manufacturing changes. Ensure environmental compliance requirements are met as RoHS status may vary. Validate supplier documentation matches the specific suffix J8.

Memory IC Selection Notes

Select this component when simultaneous independent access to shared memory is required. The 70ns speed suits moderate-frequency asynchronous applications. Consider the PLCC package constraints for PCB layout. Verify temperature range compatibility with the operational environment. Evaluate power consumption against system thermal limits.

Memory IC Part Context

This part belongs to the 71342 series of dual-port SRAMs from Renesas. It shares architectural similarities with other variants like the 71342LA20J8 but differs in speed grade and temperature rating. The series is characterized by its integrated semaphore mechanism for port arbitration.
