7143LA20PFI

Overview

The Renesas Electronics Corporation 7143LA20PFI is a dual-port static random-access memory (SRAM) integrated circuit. It provides a storage capacity of 32 kbit, organized as 2K x 16 bits. The device features an asynchronous parallel interface with a maximum access time of 20 ns. It operates within a supply voltage range of 4.5 V to 5.5 V and supports surface-mount installation in a 100-LQFP package measuring 14x14 mm. The component is designed for commercial temperature environments ranging from 0°C to +70°C.

Feature Summary

• Dual-port architecture enabling independent simultaneous access by two processors
• Asynchronous operation compatible with standard logic timing requirements
• CMOS technology ensuring low power consumption during standby and active states

Applications

• High-speed data buffering in telecommunications equipment
• Cache memory implementation in embedded processing systems
• Data storage in industrial control applications requiring fast read/write cycles

Procurement Notes

Verify the specific suffix PFI confirms the 100-LQFP package and commercial temperature grade. Confirm RoHS compliance status as legacy variants may differ. Check current availability as this series may be subject to discontinuation or limited stock. Ensure pin compatibility with existing PCB layouts before ordering.

Selection Notes

Select this component when a 32 kbit dual-port SRAM with 20 ns speed is required. Compare against the 7143SA20G for through-hole options or other packages if space constraints vary. Verify that the 2K x 16 organization matches the system data bus width. Ensure the operating temperature range meets the environmental specifications of the target application.

Part Context

This part belongs to the Renesas 7143SA/LA series of dual-port SRAMs. The LA suffix typically denotes lead-free and RoHS-compliant manufacturing processes compared to older SA variants. The series offers various access speeds and package options to support diverse memory design needs in computing and communication hardware.

Replacement Considerations

The IDT7143LA20PFI is a direct equivalent part number under the Integrated Device Technology brand, which merged into Renesas. Cross-reference datasheets to confirm identical pinouts and electrical characteristics before substitution.
