7143SA20PF

Overview

The Renesas Electronics Corporation 7143SA20PF is a high-speed dual-port static random access memory (SRAM) integrated circuit. It features a storage capacity of 32Kb, organized as 2K words by 16 bits. The device operates asynchronously with a maximum access time of 20 ns. It supports parallel interface communication and requires a single power supply voltage ranging from 4.5V to 5.5V. The component is designed for surface mount installation in a 100-pin Thin Quad Flat Package measuring 14x14 mm. It functions within an ambient operating temperature range of 0°C to 70°C.

Feature Summary

• True dual-ported memory cells enable simultaneous independent access to the same memory location from both ports without conflict.
• On-chip port arbitration logic manages data bus contention automatically, eliminating the need for external discrete control logic.
• Separate write control signals for the upper and lower bytes of each port allow flexible expansion of data bus width to 32 bits or more using slave configurations.

Applications

• High-speed real-time processing systems requiring concurrent data access
• Industrial equipment control architectures utilizing master/slave RAM topologies
• Embedded systems needing error-free operation without additional discrete logic

Procurement Notes

Verify current availability status as this component may be subject to discontinuation notices. Confirm package markings and date codes against official datasheets. Ensure environmental compliance requirements are met if RoHS exemption is necessary. Validate pin compatibility during replacement planning. Consult manufacturer documentation for specific handling and storage conditions.

Selection Notes

Select this component when simultaneous bidirectional access to shared memory is required without external arbitration hardware. Suitable for applications demanding fast asynchronous read/write cycles at 20 ns speeds. Choose based on the 100-TQFP package constraint and 5V TTL-compatible logic levels. Verify thermal performance within the specified industrial temperature range.

Part Context

This part belongs to the 7143SA series of dual-port SRAMs manufactured by Renesas Electronics. It utilizes CMOS technology to provide high-density memory in a compact form factor. The series is designed for versatile control in complex memory systems, supporting both standalone and cascaded operations for wider data buses.

Replacement Considerations

Check for direct cross-references such as IDT7143SA20PF. Verify functional equivalence regarding access times and voltage ranges. Ensure physical footprint matches the 100-TQFP specification. Review any end-of-life notifications from the manufacturer before finalizing substitution plans.
