Intel RC28F640J3D75: A 64-Mbit P30 Parallel NOR Flash Memory for Embedded Systems
In the realm of embedded systems, where reliability, speed, and non-volatility are paramount, NOR Flash memory remains a cornerstone technology. The Intel RC28F640J3D75 stands as a prominent example, a 64-megabit device built on the advanced P30 technology node. This parallel NOR Flash memory is engineered to meet the rigorous demands of applications ranging from telecommunications infrastructure and networking equipment to industrial automation and automotive systems.
A defining feature of this memory is its high-performance Parallel Interface. Operating on a 16-bit data bus, it offers fast read access times, which are critical for systems that execute code directly from flash (XiP - eXecute in Place). This capability allows microprocessors and microcontrollers to fetch instructions at high speeds without the need to first shadow code into RAM, simplifying system design and reducing both component count and cost.
The device is built upon Intel's proven P30 Flash Memory Technology. This foundation provides a robust combination of high density, excellent endurance, and reliable data retention. With a typical endurance of 100,000 program/erase cycles per sector and the ability to retain data for up to 20 years, the RC28F640J3D75 is designed for long-term deployment in mission-critical environments.
Advanced sector protection mechanisms ensure data integrity. The memory array is divided into multiple uniform 64-Kbyte sectors that can be individually locked and unlocked via software. This allows system designers to protect critical boot code or sensitive parameters from accidental modification, while still permitting updates to other sections of the memory map.
Furthermore, the component operates over a standard 2.7V to 3.6V voltage range, making it compatible with a wide array of modern low-power processors. Its extended industrial temperature range support ensures consistent operation even in harsh environmental conditions.
ICGOOODFIND: The Intel RC28F640J3D75 exemplifies a high-performance, reliable NOR Flash solution, delivering the essential speed, durability, and security features required for sophisticated embedded systems. Its parallel interface and execute-in-place capability make it an ideal choice for applications where fast boot times and immediate code execution are non-negotiable requirements.
