7028L20PFGI8

Memory IC Overview

The Renesas Electronics Corporation 7028L20PFGI8 is a dual-port, asynchronous static random-access memory (SRAM) integrated circuit. It provides a total storage capacity of 1 megabit, organized as 128K words by 8 bits. The device features parallel interface access with a maximum access time of 20 nanoseconds. It operates within a supply voltage range of 4.5V to 5.5V and supports an industrial operating temperature range from -40°C to +85°C. The component is housed in a 100-pin Thin Quad Flat Package (TQFP) with dimensions of 14x14 mm.

Memory IC Feature Summary

• Dual-port architecture enabling independent simultaneous access for two processors or systems
• Asynchronous operation allowing flexible timing integration without clock synchronization requirements
• Parallel data interface supporting standard high-speed memory bus connections

Memory IC Applications

• High-performance embedded systems requiring concurrent data access
• Industrial control units needing reliable volatile memory storage
• Telecommunications equipment utilizing asynchronous processing architectures

Memory IC Procurement Notes

Verify current manufacturing status as the component may be subject to obsolescence notices. Confirm RoHS compliance and moisture sensitivity level prior to procurement. Ensure the specific package variant matches design requirements. Check for authorized replacement parts if discontinuation is confirmed. Validate supplier authenticity to prevent counterfeit components.

Memory IC Selection Notes

Select this part when dual-port functionality is required for shared memory resources. The 20ns access speed suits moderate-to-high frequency asynchronous applications. Consider the 100-TQFP package constraints for PCB layout. Evaluate power consumption against system thermal limits. Compare organizational structure with alternative single-port devices if concurrency is unnecessary.

Memory IC Part Context

This component belongs to the Renesas 7028L series of dual-port SRAMs. It shares architectural similarities with other members like the 7025L20PFGI8 but differs in memory organization and capacity. The series targets applications demanding independent read/write ports for enhanced system throughput and reduced bus contention.
