7143LA35GB

Overview

The Renesas 7143LA35GB is a 32Kbit dual-port asynchronous SRAM with a 2K x 16 memory organization. It operates on a single 5V (±10%) power supply within a voltage range of 4.5V to 5.5V. The device features a 35ns access time and supports parallel interface communication. It is housed in a 68-pin PLCC package designed for surface mount technology. The component functions within an industrial temperature range of 0°C to 70°C.

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, enabling full-speed error-free operation in 32-bit or wider systems without discrete logic.
• Configurable I/O voltage levels are supported via internal pull-ups and tri-state control mechanisms.

Applications

• High-speed data buffering in network equipment
• Cache memory implementation in embedded processors
• Real-time signal processing systems

Procurement Notes

Verify component authenticity through authorized distributors due to potential legacy status. Confirm RoHS compliance requirements as older batches may not meet current environmental standards. Check moisture sensitivity level handling procedures during assembly. Validate pin compatibility with existing PCB footprints before integration into new designs.

Selection Notes

Select this component when simultaneous bidirectional data access is required for high-throughput applications. Ensure system design accommodates the 68-pin PLCC package constraints. Verify that the 35ns speed meets timing requirements. Consider power consumption limits associated with the 5V supply architecture.

Part Context

This part belongs to the 7143 series of dual-port static random-access memories manufactured by Renesas Electronics Corporation. The series utilizes IDT MASTER/SLAVE Dual-Port RAM approach technology. It serves as a specialized memory solution for complex digital systems requiring concurrent read/write operations.

Replacement Considerations

IDT7143LA35J8 is a confirmed substitute part number within the same family offering equivalent specifications and functionality.
