Intel JS28F00AM29EWH 3V 128Mbit Parallel NOR Flash Memory: Datasheet Overview and Product Specifications

The Intel JS28F00AM29EWH is a high-performance 3V 128Mbit Parallel NOR Flash memory device designed for a wide range of embedded applications requiring reliable, non-volatile storage and fast read operations. As a member of Intel's renowned advanced NOR Flash family, this component is engineered for systems where execute-in-place (XIP) capability is crucial, allowing microprocessors to run code directly from the flash memory without needing to copy it to RAM first.

A key feature of this memory is its parallel interface, which provides a high-speed data path essential for performance-critical applications. Organized as 16,777,216 bits (128 Megabits) or 8,388,608 words by 16 bits, it offers flexible storage for complex firmware, boot code, and configuration data. Operating at a standard 3.0-volt core and I/O supply voltage, it is suitable for modern low-power systems while maintaining compatibility with various microcontrollers and processors.

The device supports a asynchronous memory access mode, making it highly versatile for interfacing with numerous system architectures. Its page mode reading capability further enhances performance by allowing faster sequential access. For write operations, it incorporates a block locking mechanism that provides both hardware and software protection for critical code segments, preventing accidental overwrites and enhancing system security.

Programming and erasure are managed through a command-driven interface that complies with the Common Flash Memory Interface (CFI) standards, ensuring easy integration and software portability. The chip features a durable architecture rated for a minimum of 100,000 write/erase cycles per sector and offers a data retention period of up to 20 years, guaranteeing long-term reliability.

Typical applications include networking equipment (routers, switches), telecommunications infrastructure, industrial control systems, and automotive electronics, where robust and dependable storage is mandatory.

ICGOODFIND: The Intel JS28F00AM29EWH stands out as a robust and reliable solution for demanding embedded systems, offering an optimal blend of high-speed parallel access, superior reliability, and efficient power consumption.
