71321LA55TF8

Memory IC Overview

The 71321LA55TF8 is a dual-port static random access memory (SRAM) integrated circuit manufactured by Renesas Electronics Corporation. It features a storage capacity of 16 kilobits organized as 2K words by 8 bits. The device operates with an asynchronous parallel interface and supports a maximum access time of 55 nanoseconds. It functions within a supply voltage range of 4.5 volts to 5.5 volts. The component is housed in a surface-mount 64-pin Thin Quad Flat Package (TQFP) measuring 14x14 millimeters. It is designed for industrial temperature ranges spanning from -40°C to +85°C.

Memory IC Feature Summary

• Supports simultaneous independent read and write operations at both Port A and Port B without bus contention.
• Provides high-speed asynchronous data transfer capabilities suitable for complex system architectures.
• Integrates internal master/slave logic to manage data flow between the two ports.

Memory IC Applications

• High-performance digital signal processing systems requiring low-latency memory access.
• Industrial automation controllers needing reliable data buffering.
• Telecommunications equipment utilizing dual-port memory for protocol handling.

Memory IC Procurement Notes

Verify the exact suffix configuration against official Renesas documentation, as variations such as TFG8 or PFG8 indicate different packaging or environmental compliance standards. Confirm RoHS status and moisture sensitivity levels prior to integration. Ensure compatibility with existing board layouts regarding the 64-TQFP footprint and pin assignments.

Memory IC Selection Notes

Select this component when a design requires true dual-port functionality with independent address and data buses. Compare performance metrics against single-port alternatives if cost reduction is prioritized over concurrent access speeds. Validate that the 55 ns access time meets the timing requirements of the target processor or controller interface.

Memory IC Part Context

This part belongs to the 71321 series of dual-port SRAMs, which are widely used in applications demanding high throughput and deterministic memory access. The series offers various speed grades and package options to accommodate diverse system constraints while maintaining consistent electrical characteristics across the family.

Memory IC Replacement Considerations

Consult official Renesas substitution guides for verified equivalents. Potential cross-references may include other 71321 variants with adjusted speed grades or packaging suffixes, provided they maintain identical pinouts and functional specifications.
