7028L20PFI8

Memory IC Overview

The Renesas Electronics Corporation 7028L20PFI8 is a 1 Mbit (128K x 8) asynchronous dual-port static random-access memory. It operates within a supply voltage range of 4.5 V to 5.5 V and features a maximum access time of 20 ns. The device supports independent read/write operations at both ports simultaneously, facilitating high-speed data transfer in complex system architectures. It is housed in a 100-pin Thin Quad Flat Package with an exposed pad (TQFP-100), designed for surface-mount technology applications requiring robust parallel interface connectivity.

Memory IC Feature Summary

• Supports simultaneous independent read and write operations at Port A and Port B without bus contention
• Provides flexible configuration options for byte-wide or word-wide data access through dedicated control pins
• Integrates power-down mode functionality to minimize current consumption during inactive periods

Memory IC Applications

• High-performance digital signal processing systems requiring low-latency data buffering
• Network communication equipment utilizing packet switching and routing logic
• Industrial automation controllers managing real-time sensor data acquisition

Memory IC Procurement Notes

Verify component authenticity through authorized distributors due to potential counterfeit risks in the secondary market. Confirm RoHS compliance status and moisture sensitivity level handling requirements prior to assembly. Ensure that the specific suffix matches the required package variant and temperature grade for your design implementation.

Memory IC Selection Notes

Select this component when designing systems necessitating true dual-port memory architecture for concurrent processor access. Evaluate the 20 ns access speed against system clock requirements to ensure timing compatibility. Consider the TQFP-100 footprint constraints and thermal dissipation characteristics relative to your printed circuit board layout capabilities.

Memory IC Part Context

This part belongs to the Renesas 7028L20 series of asynchronous dual-port SRAMs. It shares architectural similarities with other members like the 70261L20 but differs in organization and pinout configurations. The series is engineered for applications demanding high bandwidth and deterministic access times in embedded environments.

Memory IC Replacement Considerations

Consult official cross-reference documentation for compatible alternatives such as the IDT7028L20PFI8. Verify electrical parameter equivalence and pin-to-pin compatibility before substitution.
