7028L20PF8

Memory IC Overview

The 7028L20PF8 is a dual-port static random-access memory (SRAM) integrated circuit manufactured by Renesas Electronics. It provides a total storage capacity of 1 megabit, organized as 64K words by 16 bits. The device features asynchronous parallel interface operation with a maximum access time of 15 nanoseconds. It operates within a supply voltage range of 4.5V to 5.5V and supports surface-mount installation in a 100-pin Thin Quad Flat Package (TQFP). The component is designed for industrial temperature ranges from 0°C to +70°C.

Memory IC Feature Summary

• Supports independent simultaneous read/write operations at both Port A and Port B without conflict
• Provides high-speed asynchronous data transfer with 15ns access time
• Utilizes standard parallel interface for straightforward system integration

Memory IC Applications

• High-performance embedded systems requiring fast local memory
• Industrial control units needing reliable data buffering
• Telecommunications equipment utilizing dual-port memory architectures

Memory IC Procurement Notes

Verify the specific suffix 'PF8' against official Renesas documentation to confirm package type and moisture sensitivity level. Confirm RoHS compliance status as historical data may vary. Check current lifecycle status as this part number may be discontinued or subject to last-time buy restrictions. Ensure design-in compatibility with existing PCB footprints for the 100-TQFP package.

Memory IC Selection Notes

Select this component when a 1Mb dual-port SRAM with 16-bit width is required. Compare access speeds against other variants in the 7028L series if faster performance is needed. Verify that the 4.5V to 5.5V operating voltage aligns with the target system power rails. Consider the 100-pin TQFP package constraints for board space and thermal management requirements.

Memory IC Part Context

This device belongs to the 7028L family of dual-port SRAMs from Renesas. It shares architectural similarities with other members like the 7028L15PFG8 but differs in speed grade and packaging. The family is characterized by its ability to handle concurrent accesses from two independent masters, making it suitable for complex data processing tasks.

Memory IC Replacement Considerations

Check for direct pin-compatible substitutes within the 7028L series. Verify if newer generations from Renesas offer equivalent functionality with improved compliance standards.
