Intel RC28F320J3A110: A 32Mb NOR Flash Memory for Embedded Systems

In the realm of embedded systems, where reliability, performance, and non-volatility are paramount, NOR Flash memory remains a foundational technology. The Intel RC28F320J3A110 stands as a prominent example, offering a robust 32-megabit (4MB) storage solution tailored for demanding applications. This device exemplifies Intel’s legacy in producing high-quality memory components, providing critical features that ensure seamless operation in sectors such as automotive, industrial automation, telecommunications, and aerospace.

One of the standout attributes of the RC28F320J3A110 is its advanced architecture, which supports a 3.0-volt single power supply, making it suitable for low-power embedded environments. Its 128-bit wide data bus enables rapid access times, crucial for execute-in-place (XIP) operations, where code is run directly from flash rather than being copied to RAM. This significantly enhances system boot times and overall responsiveness.

The device is built with a symmetric block structure, featuring multiple 64 KB blocks that can be independently erased and rewritten. This flexibility is essential for firmware updates and data storage management. Moreover, it incorporates hardware and software write protection mechanisms, safeguarding critical code segments from accidental corruption—a vital requirement in safety-critical systems.

Compatibility and longevity are also key strengths. The RC28F320J3A110 supports the Common Flash Memory Interface (CFI), allowing host systems to automatically identify and configure the memory, thereby simplifying design integration. Its extended temperature range and endurance characteristics ensure reliable performance even in harsh operating conditions.

ICGOOODFIND: The Intel RC28F320J3A110 remains a trusted and efficient solution for embedded systems, combining high-speed access, flexible memory management, and robust protection features to meet the rigorous demands of modern electronic designs.
