7142SA35L48B

Memory IC 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.

Memory IC Feature Summary

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

Memory IC Applications

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

Memory IC 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.

Memory IC 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.

Memory IC 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.

Memory IC Replacement Considerations

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