Memory IC datasheet and documents for 7142LA35J8

7142LA35J8

Memory IC Overview

The Renesas Electronics Corporation 7142LA35J8 is a high-speed 2K x 8 dual-port static RAM. It operates on a single 5V ±10% power supply with a voltage range of 4.5V to 5.5V. The device features an access time of 35ns and supports battery backup operation for data retention down to 2V. It utilizes TTL-compatible logic levels and is housed in a 52-pin PLCC package designed for surface mount technology.

Memory IC Feature Summary

True dual-ported memory architecture enabling simultaneous independent access to the same memory location by both ports
Automatic power-down functionality controlled by chip enable inputs to achieve very low standby power consumption
Battery backup capability ensuring data retention at voltages as low as 2V

Memory IC Applications

High-speed parallel data buffering in communication systems
Cache memory implementation in embedded processing architectures
Data storage within industrial control system interfaces

Memory IC Procurement Notes

Verify component authenticity through authorized channels due to end-of-life status. Confirm package integrity and lead condition upon receipt. Validate datasheet revisions against specific manufacturing lot codes to ensure compliance with original electrical specifications and pinout definitions.

Memory IC Selection Notes

Select this component when true dual-port simultaneous access is required without external arbitration logic. Suitable for applications needing fast write cycles and low standby power. Ensure design accommodates the 52-pin PLCC footprint and 4.5V to 5.5V operating voltage constraints.

Memory IC Part Context

Part of the 7142 series of dual-port SRAMs, designed to function as a slave device alongside master counterparts like the 7132. This series provides full-speed error-free operation in wider word configurations without additional discrete logic. The LA suffix indicates commercial temperature range availability.
