7142SA35C

Overview

The Renesas Electronics Corporation 7142SA35C is a dual-port, asynchronous static random-access memory (SRAM) integrated circuit. It provides a storage capacity of 16K bits, organized as 2K words by 8 bits. The device features a parallel interface with an access time and write cycle time of 35 nanoseconds. It operates within a supply voltage range of 4.5V to 5.5V and supports surface-mount installation in a 48-SIDE BRAZED package. The component is designed for commercial temperature ranges.

Feature Summary

• Supports simultaneous independent read/write operations at both ports without conflict
• Utilizes CMOS technology for low power consumption and high-speed performance
• Features asynchronous operation compatible with various system clock speeds

Applications

• High-speed data buffering in communication systems
• Cache memory implementation in embedded processors
• Data storage in industrial control applications

Procurement Notes

Verify the specific package variant and lead count, as historical records indicate variations such as 48-lead configurations. Confirm RoHS compliance status, as older batches may differ from current manufacturing standards. Ensure compatibility with existing board layouts due to the specialized SIDE BRAZED packaging type. Check for end-of-life notices or obsolescence warnings before finalizing procurement plans.

Selection Notes

Select this component when dual-port functionality is required for concurrent data handling between two independent masters. Consider the 35ns access speed for moderate-to-high frequency applications. Evaluate the 4.5V to 5.5V operating range against system power rails. Assess the physical footprint requirements of the SIDE BRAZED package against available PCB space.

Part Context

This part belongs to the 7142SA series of dual-port SRAMs from Renesas. It shares architectural similarities with other members like the 71421SA35PF but differs in organization and package. The series is characterized by its ability to eliminate bus contention through separate port controls.
