7143LA55PF

Overview

The Renesas Electronics Corporation 7143LA55PF is a dual-port static random access memory (SRAM) integrated circuit. It features an 8K-bit storage capacity organized as 1K words by 8 bits. The device utilizes asynchronous parallel interface technology with a maximum access time of 55 nanoseconds. It operates within a supply voltage range of 4.5V to 5.5V and supports surface-mount installation in a 64-pin Thin Quad Flat Package (TQFP). The component is designed for commercial temperature ranges spanning from 0°C to 70°C.

Feature Summary

• Dual-port architecture enabling independent simultaneous read/write operations on separate ports
• Asynchronous parallel interface supporting standard logic levels
• CMOS technology ensuring low power consumption during operation

Applications

• High-speed data buffering in communication systems
• Cache memory implementation in embedded processors
• FIFO buffer applications in digital signal processing

Procurement Notes

Verify the specific suffix 'PF' against official Renesas documentation to confirm package type and pinout compatibility. Confirm RoHS compliance status as older variants may differ. Check for product discontinuance notices or end-of-life announcements prior to procurement planning. Ensure moisture sensitivity level handling procedures are followed during assembly.

Selection Notes

Select this component when a dual-port SRAM solution is required for applications needing concurrent access from two different masters. Compare access times and power specifications against alternative devices in the 7143 series. Verify that the 64-TQFP package fits the available board space and thermal requirements. Ensure voltage levels match the system's 5V logic standards.

Part Context

This part belongs to the Renesas 7143SA/LA series of dual-port SRAMs. These components are widely used in industrial and telecommunications equipment requiring reliable, high-speed memory solutions. The LA variant typically denotes specific package and temperature characteristics compared to the SA series.

Replacement Considerations

Consult official Renesas substitution guides for compatible alternatives. Verify pin-to-pin compatibility and electrical parameter equivalence before replacing.
