XM25QU128: A Low-Power Domestic NOR Flash Chip Fully Compatible with W25Q128JVSIQ.

As a leading domestic memory chip enterprise, Wuhan Xinxin XMC continues to deepen its expertise in non-volatile memory fields such as NOR Flash. Its high-performance 128Mbit Serial NOR Flash chip, the XM25QU128CHIQT08Q, has achieved large-scale application in various sectors including consumer electronics and industrial control, thanks to its good data retention, high reliability, and excellent power efficiency.

Building upon the inherent advantages of NOR Flash—such as support for eXecute-In-Place (XIP) mode and high-speed interfaces—this chip further optimizes key performance indicators, positioning it as a highly compatible alternative to Winbond's W25Q128JVSIQ. Its pinout, voltage range, instruction set, and packaging are fully aligned with the W25Q128JVSIQ, enabling seamless hardware-level replacement and significantly reducing switching costs for module manufacturers.

The XM25QU128CHIQT08Q provides 128Mbit of storage capacity, sufficient to meet the firmware storage and data caching needs of most embedded systems. Leveraging advanced manufacturing processes, the chip maintains a high-speed read performance of 133MHz while controlling the typical standby current below 10µA. It also supports a deep power-down mode, notably extending the battery life of powered devices.

In terms of reliability, the chip supports over 100,000 program/erase cycles and more than 20 years of data retention. It incorporates certain electromagnetic interference (EMI) resistance designs, making it suitable for wide-temperature and noisy environments common in industrial settings. Some versions also integrate an Error Correction Code (ECC) mechanism that can automatically correct data in case of minor bit flips, enhancing long-term operational stability.

The XM25QU128CHIQT08Q features built-in One-Time Programmable (OTP) memory and hardware-level security functions. These can be used to store unique device identifiers or encryption keys, providing foundational support for firmware tamper resistance and sensitive data protection, aligning with the growing security demands of IoT devices.

Through its high compatibility, low power consumption, high reliability, and domestic supply chain assurance, the XM25QU128CHIQT08Q offers a pragmatic and efficient NOR Flash solution for communication modules, industrial terminals, and smart hardware. As the industry places increasing emphasis on supply chain security, the XM25QU128CHIQT08Q, with its high compatibility to the W25Q128 series, has become a domestic alternative that many manufacturers are willing to adopt.
