PC28F640J3F75B

Memory IC Overview

The PC28F640J3F75B is a 64 Mbit (8M x 8 or 4M x 16) Embedded Parallel NOR Flash memory IC manufactured by Micron Technology. It operates within a voltage range of 2.7 V to 3.6 V and features a fast access time of 75 ns. The device is housed in a 64-pin EasyBGA package with dimensions of 10x13 mm and is supplied in tape and reel format.

Memory IC Feature Summary

• Supports parallel interface for high-speed data access
• Operates on standard 3V/3.3V power supply
• Compact BGA packaging for space-constrained designs

Memory IC Applications

• Embedded storage in industrial control systems
• Code execution from flash (XIP) applications
• Consumer electronics firmware storage

Memory IC Procurement Notes

Verify the specific suffix 'TR' indicates tape and reel packaging configuration. Confirm the 75 ns access time aligns with system timing requirements. Ensure the 64-EasyBGA footprint matches the PCB layout. Check current availability status as this part may be subject to lifecycle changes.

Memory IC Selection Notes

Select this component when a parallel NOR interface is required for direct code execution. The 64 Mbit density suits moderate capacity needs. The 75 ns speed offers a balance between performance and power consumption. Verify compatibility with the target microcontroller's address and data bus widths.

Memory IC Part Context

This part belongs to Micron's 3V Embedded Parallel NOR Flash family, which includes 32Mb, 64Mb, and 128Mb densities. These devices are designed for embedded applications requiring reliable non-volatile storage with fast random access capabilities.

Memory IC Replacement Considerations

Consult Micron's obsolete part catalog for verified substitutes. Potential equivalents include other 64 Mbit parallel NOR flashes from Micron or compatible vendors, ensuring pinout and electrical specifications match.
