7143SA35PF

Overview

The Renesas Electronics Corporation 7143SA35PF is a high-speed, 32Kb (2K x 16) dual-port static random-access memory (SRAM). It features asynchronous parallel interface operation with a 35 ns access time. The device operates on a single 5V power supply within the 4.5V to 5.5V range and supports battery backup for data retention. It is housed in a 100-pin TQFP surface-mount package.

Feature Summary

• True dual-ported memory cells allow simultaneous independent access to the same memory location from both ports without conflict.
• On-chip port arbitration logic manages bus contention automatically, eliminating the need for external discrete logic components.
• Supports versatile write control with separate byte enables for each port, facilitating expansion of data bus widths beyond 16 bits.

Applications

• High-performance digital signal processing systems requiring concurrent data access
• Telecommunications equipment utilizing master/slave dual-port configurations
• Industrial automation controllers needing fast, reliable volatile storage

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status as historical batches may vary. Check for obsolescence notices or end-of-life announcements prior to finalizing procurement plans to ensure long-term supply stability.

Selection Notes

Select this component when simultaneous read/write operations are required without external arbitration hardware. Ensure system design accommodates the 100-pin TQFP footprint and 5V logic levels. Consider thermal dissipation requirements for dense PCB layouts using this surface-mount package.

Part Context

This part belongs to the 7143SA series of dual-port SRAMs, designed for applications demanding high throughput and low latency. It utilizes CMOS technology to provide efficient power consumption while maintaining fast access speeds suitable for complex embedded memory architectures.

Replacement Considerations

Consult official datasheets for pin-compatible alternatives such as the 7143LA series. Verify electrical specifications and package dimensions match before substitution. No specific substitute part numbers are confirmed in public documentation.
