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).
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.
Applications
- Data buffering in communication systems
- Cache memory applications
- Industrial control systems
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.
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.
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.
Replacement Considerations
Consult official documentation for verified substitute part numbers. Cross-reference pinouts and electrical characteristics carefully when evaluating alternatives.
