Memory IC Overview

The Renesas Electronics Corporation 7140SA55PF is a dual-port static random-access memory (SRAM) integrated circuit. It provides an 8-kilobit storage capacity organized as 1K words by 8 bits. The device utilizes a parallel interface with asynchronous operation, featuring a maximum access time of 55 nanoseconds. It operates within a supply voltage range of 4.5V to 5.5V and supports through-hole mounting in a 48-pin plastic dual in-line package (PDIP).

Memory IC Feature Summary

Dual-port architecture enabling independent simultaneous read/write operations on both ports.
Asynchronous parallel interface for straightforward system integration.
CMOS technology providing high-speed data access capabilities.

Memory IC Applications

Data buffering in communication systems
Cache memory applications
Industrial control systems

Memory IC Procurement Notes

Verify component authenticity due to discontinuation status. Confirm RoHS compliance requirements as the part may not meet current environmental standards. Validate pin compatibility and electrical specifications against target design parameters before procurement.

Memory IC Selection Notes

Select this component for designs requiring independent dual-port memory access. Ensure the application supports 5V logic levels and through-hole assembly processes. Verify that the 55ns speed meets timing constraints.

Memory IC Part Context

This part belongs to the 7140SA series of dual-port SRAMs from Renesas Electronics. It serves as a legacy component for systems requiring non-volatile-free high-speed memory with separate port control lines.

Memory IC Replacement Considerations

Consult official documentation for verified substitute part numbers. Cross-reference pinouts and electrical characteristics carefully when evaluating alternatives.
