7142SA35L48B

Overview

The Renesas Electronics Corporation 7142SA35L48B is a high-speed dual-port static random access memory (SRAM) device. It features a storage capacity of 16 kilobits, organized as 2K words by 8 bits per word. The component utilizes a parallel interface with an access 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-pin Leadless Ceramic Chip Carrier (LCC) package.

Feature Summary

• True dual-ported architecture enabling simultaneous independent access to the same memory location from two separate ports.

Applications

• High-speed data buffering in communication systems
• Cache memory implementation in embedded processors
• Data acquisition systems requiring concurrent read/write operations

Procurement Notes

Verify RoHS compliance status as the component may not meet current environmental directives. Confirm package dimensions against the 48-LCC specification. Check for end-of-life notices or obsolescence warnings before finalizing procurement plans.

Selection Notes

Select this component when true dual-port functionality is required for simultaneous data access. Ensure the system design accommodates the 48-pin LCC package constraints. Verify that the 35ns access speed meets the timing requirements of the target application bus.

Part Context

This part belongs to the 7142 series of dual-port SRAMs manufactured by Renesas Electronics. These devices are designed to operate without additional discrete logic for basic dual-port control, simplifying system design compared to single-port alternatives.

Replacement Considerations

Consult official documentation for verified substitute part numbers. Cross-reference pinouts and electrical specifications carefully when evaluating alternative components.
