7140LA20PF8

Overview

The Renesas Electronics Corporation 7140LA20PF8 is an asynchronous dual-port static random-access memory (SRAM) IC. It provides a storage capacity of 8 kilobits, organized as 1K words by 8 bits. The device features a parallel interface with a maximum access time of 20 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) measuring 14x14 mm.

Feature Summary

• Supports simultaneous independent read/write operations via two separate port interfaces for concurrent data handling.

Applications

• Real-time data buffering in high-speed digital signal processing systems
• Cache memory implementation in embedded microcontroller architectures
• FIFO buffer applications requiring low-latency data transfer

Procurement Notes

Verify component authenticity through authorized channels due to potential availability constraints. Confirm RoHS compliance status and moisture sensitivity level prior to assembly. Ensure proper ESD handling protocols are followed during storage and placement. Validate pin compatibility with existing PCB footprints before procurement.

Selection Notes

Select this component when dual-port functionality is required for concurrent master-slave or peer-to-peer data exchange. The 20ns access speed suits moderate-frequency synchronous logic. Verify that the 64-TQFP package fits the design constraints and that the 4.5V-5.5V supply aligns with the system power rails.

Part Context

This part belongs to the IDT/Renesas 7140SA/LA series of CMOS dual-port SRAMs. It shares architectural similarities with other members like the 7130LA and 7140SA variants, differing primarily in organization and package options. The LA suffix typically denotes specific temperature or commercial grade variations within the broader product family.

Replacement Considerations

Direct substitutes include the 7140SA20PF8, which shares identical electrical specifications and pinout but may differ in manufacturing origin or minor qualification standards. Cross-reference datasheets to ensure functional equivalence regarding timing parameters and power consumption profiles.
