PC28F320J3D75E

Memory IC Overview

The PC28F320J3D75E is a 32 Mbit Parallel NOR Flash memory component manufactured by Micron Technology Inc. It belongs to the StrataFlash embedded flash family and features a 56-pin Thin Small Outline Package (TSOP). The device supports asynchronous parallel access with a maximum access time of 75 ns. It operates within a voltage range of 2.7 V to 3.6 V and is rated for an industrial temperature range of -40°C to +85°C.

Memory IC Feature Summary

• Supports asynchronous parallel interface for direct host connection
• Provides non-volatile data retention for embedded applications
• Operates within standard industrial temperature specifications

Memory IC Applications

• Embedded firmware storage in industrial control systems
• Code execution from memory (XIP) in consumer electronics
• Data logging in automotive telematics units

Memory IC Procurement Notes

Verify the specific suffix 'E' against official Micron documentation, as it may denote environmental compliance or package variations. Confirm current lifecycle status, as older StrataFlash parts are frequently discontinued. Ensure the required 75 ns speed grade matches system timing constraints before procurement.

Memory IC Selection Notes

Select this part when a 32 Mbit capacity with parallel interface is required for code storage. Compare against the JS28F320 series for pin compatibility and feature parity. Verify that the 56-TSOP package fits the PCB footprint and that the 2.7V-3.6V supply rail aligns with the target system design.

Memory IC Part Context

This component is part of Micron's legacy StrataFlash portfolio, designed for embedded applications requiring high reliability and fast random access. It serves as a replacement for earlier generations of parallel NOR flash in established designs where 32 Mbit density is sufficient.

Memory IC Replacement Considerations

Consult Micron's cross-reference guides for verified substitutes. The JS28F320J3D75 series shares similar electrical characteristics and pinouts. Verify if newer revisions offer improved endurance or updated packaging options.
