71321LA35PFI

Memory IC Overview

The Renesas Electronics Corporation 71321LA35PFI is a dual-port static random-access memory (SRAM) integrated circuit. It features a storage capacity of 16 kilobits organized as 2K words by 8 bits. The device utilizes an asynchronous parallel interface with a maximum access time of 35 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. The component is rated for an industrial operating temperature range from -40°C to +85°C.

Memory IC Feature Summary

• Provides independent read/write ports for simultaneous data access
• Supports high-speed asynchronous parallel data transfer
• Designed for reliable operation across extended industrial temperature ranges

Memory IC Applications

• Real-time data buffering in industrial control systems
• High-speed cache memory in embedded processing architectures
• Data logging applications requiring rapid write cycles

Memory IC Procurement Notes

Verify the specific suffix configuration against official datasheets, as package variations exist within this product family. Confirm RoHS compliance status, as earlier manufacturing lots may differ from current specifications. Ensure the selected variant matches the required thermal and electrical parameters for the target application environment before finalizing procurement.

Memory IC Selection Notes

Select this component when dual-port functionality is required for concurrent master-slave or peer-to-peer data exchange. Compare access times and power consumption against single-port alternatives if only sequential access is needed. Verify that the 64-TQFP footprint aligns with existing PCB layout constraints and thermal management requirements.

Memory IC Part Context

This part belongs to the 71321SA/LA series of dual-port SRAMs manufactured by Renesas Electronics. The 'LA' designation typically indicates specific voltage and temperature characteristics distinct from the 'SA' series. These devices are engineered for applications demanding high bandwidth and low latency in complex digital signal processing environments.

Memory IC Replacement Considerations

Check for direct pin-compatible upgrades such as the 71321LA25PFGI for faster performance. Verify functional equivalence with other 16Kb dual-port SRAMs if sourcing from alternative manufacturers.
