7142SA35J

Overview

The Renesas Electronics Corporation 7142SA35J is a dual-port, asynchronous SRAM IC with a storage capacity of 16Kb organized as 2K x 8. It features a parallel interface and operates within a supply voltage range of 4.5V to 5.5V. The component has an access time of 35 ns and functions at temperatures between 0°C and 70°C. It is housed in a 52-PLCC surface-mount package measuring 19.13x19.13 mm.

Feature Summary

• Supports simultaneous independent access to the same memory location by both ports.

Applications

• High-speed data buffering in embedded systems
• Real-time processing applications requiring low latency
• Industrial equipment control modules

Procurement Notes

Verify RoHS compliance status as documentation indicates non-compliance. Confirm end-of-life status and last-time-buy availability through authorized channels. Ensure environmental specifications meet operational requirements for the intended deployment environment.

Selection Notes

Select this component for designs requiring true dual-port memory architecture without external arbitration logic. Verify that the 52-PLCC package fits the PCB layout constraints. Ensure the system power supply remains stable within the specified voltage range to maintain reliable operation.

Part Context

This device belongs to the 7142SA series of high-speed dual-port static RAMs. It is designed to operate as a slave unit alongside master dual-port devices to expand word width in 16-bit or larger systems. The series provides full-speed error-free operation without additional discrete logic.

Replacement Considerations

Public confirmed substitute part numbers: None available.
