Memory IC Overview

The Renesas Electronics Corporation 71342LA25JI8 is a high-speed, 32-kbit (4K x 8) dual-port static random-access memory. It features fully asynchronous parallel operation with independent access from either port and includes on-chip semaphore logic for hardware arbitration. The device operates within a supply voltage range of 4.5V to 5.5V and supports battery backup data retention at 2V. It is housed in a 52-pin PLCC package and is rated for an industrial operating temperature range of -40°C to +85°C.

Memory IC Feature Summary

True dual-ported memory cells allowing simultaneous access to the same location
Fully asynchronous operation from either port
On-chip hardware semaphore signaling for port arbitration
Battery backup capability for data retention

Memory IC Applications

High-speed real-time engine memory buffers
Industrial equipment control systems
Dual-processor communication interfaces
Asynchronous FIFO implementations

Memory IC Procurement Notes

Verify component authenticity through authorized channels due to potential availability constraints. Confirm that the specific suffix corresponds to the 52-pin PLCC package variant. Ensure procurement specifications align with the required industrial temperature range and TTL-compatible power supply requirements before finalizing orders.

Memory IC Selection Notes

Select this component when independent dual-port access and hardware semaphore support are required. It is suitable for applications needing asynchronous parallel interfaces with low standby power modes. Verify compatibility with 5V logic levels and ensure the 52-pin PLCC footprint fits the target PCB design constraints.

Memory IC Part Context

This part belongs to the 71342LA series of dual-port SRAMs. It shares architectural similarities with other variants like the 71342SA but differs in speed grade and package type. The LA designation indicates extended temperature capabilities compared to commercial grades.
