7143LA35PF8

Overview

The Renesas 7143LA35PF8 is a dual-port, asynchronous static random-access memory (SRAM) integrated circuit. It provides a storage capacity of 32K bits organized as 4K words by 8 bits. The device features a parallel interface with a maximum access time and write cycle time of 35 nanoseconds. It operates within a supply voltage range of 4.5V to 5.5V and supports surface-mount installation in a 100-TQFP package measuring 14x14 mm. The component functions reliably across an ambient temperature range of 0°C to 70°C.

Feature Summary

• Supports simultaneous independent read/write operations at two distinct ports for high-throughput data handling
• Utilizes CMOS technology to ensure low power consumption during operation
• Provides asynchronous parallel interface compatibility for straightforward system integration

Applications

• High-speed data buffering in telecommunications equipment
• Cache memory implementation in industrial control systems
• Data storage in embedded network processing units

Procurement Notes

Verify the specific suffix PF8 confirms the 100-TQFP package configuration before ordering. Confirm RoHS compliance status as older batches may not meet current environmental regulations. Check for Last Time Buy notifications due to potential end-of-life status. Ensure voltage requirements match the 4.5V to 5.5V specification for reliable operation.

Selection Notes

Select this component when dual-port architecture is required for concurrent master-slave or peer-to-peer data exchange. Compare against single-port alternatives if only one processor accesses the memory. Verify that the 35ns speed meets the system timing constraints. Ensure the 100-pin footprint fits the available PCB real estate.

Part Context

This part belongs to the Renesas 7143LA series of dual-port SRAMs. It shares architectural similarities with other members like the 7140LA but offers higher density. The LA suffix typically denotes standard voltage operation compared to LV variants. It serves as a legacy solution for designs requiring non-volatile-like speed without retention.

Replacement Considerations
