Overview
The 7140SA70JI is an asynchronous dual-port static random-access memory (SRAM) integrated circuit manufactured by Renesas Electronics Corporation. It provides a storage capacity of 8 kilobits, organized as 1K words by 8 bits per word. The device features parallel interface access with a maximum access time of 70 nanoseconds. It operates within a supply voltage range of 4.5V to 5.5V and supports surface-mount installation in a 52-pin PLCC package measuring 19.13mm x 19.13mm. The component is rated for an operating temperature range of -40°C to +85°C.
Feature Summary
- Dual-port architecture enabling independent simultaneous read/write operations on separate ports
- Asynchronous operation without requiring external clock synchronization signals
- CMOS technology providing low power consumption characteristics
Applications
- High-speed data buffering in embedded systems
- Cache memory implementation in microcontroller-based designs
- Data storage in industrial control applications
Procurement Notes
Verify the exact suffix designation, as official documentation lists 7140SA70JI8. Confirm RoHS compliance status, as specific variants may not meet current environmental regulations. Check availability as the product line may be discontinued or subject to limited supply constraints.
Selection Notes
Select this component when dual-port functionality is required for concurrent processor access. Ensure the design accommodates the 52-PLCC footprint and 4.5V to 5.5V power requirements. Consider the 70ns access speed against system timing constraints and verify temperature ratings match the operational environment.
Part Context
This part belongs to the 7140SA series of dual-port SRAMs from Renesas. The series offers various access speeds and packaging options to suit different performance and form-factor needs in electronic circuits.
Replacement Considerations
Check for direct pin-compatible substitutes within the same family, such as 7140SA70J. Verify electrical specifications and package dimensions before substitution.
