Nuremberg, Germany (March 10, 2026) — GigaDevice (HKEX: 3986), a leading semiconductor company specializing in Flash memory, 32-bit microcontrollers (MCUs), sensors, and analog products, today announced the expanded density range of its GD25UF series 1.2V ultra-low power SPI NOR Flash, now spanning from 8Mb to 256Mb. This expansion precisely addresses diverse storage needs across wide range of applications from the advanced high performance AI computing space to the low power battery operated devices. From its intrinsic low-voltage and ultra-low power performance, portable devices like wearables, hearables, AI ASIC platforms, medical devices, and other fast-growing emerging markets can have longer battery life while driving device miniaturization from edge AI to ultra-compact form factors.
Powering the Low-Voltage SoC Era with a Smarter System Architecture
As semiconductor processes advance, the operating voltage of leading-edge SoCs and processors has shifted toward 1.2V to achieve higher energy efficiency. The GD25UF series operates between 1.14V and 1.26V, perfectly aligning with this low-voltage trend.
Designed for seamless power integration with 1.2V SOCs, the GD25UF series removes the need for extra level shifters or complex power management. This streamlined architecture cuts peripheral components and BOM cost, while enhancing energy efficiency by eliminating power conversion losses.
Scaling Capacity for Both AI Performance and Ultra-Compact Designs
As the AI infrastructure continues to expand from hyperscale data centers to the edge, AI servers, high-performance computing platforms, and machine learning systems are facing rapidly growing demands driven by larger models, more complex inference tasks, and massive data movement. From code storage in hyperscale data centers platforms, to high-bandwidth memory interconnects such as CXL, and high-speed data transmission through fiber-optic transceivers, reliable local non-volatile storage is becoming increasingly critical. Accordingly, the GD25UF series now extends up to 256Mb, providing ample space to support AI inference efficiency and flexible system architectures.
Simultaneously, for space-constrained applications like IoT, wearables, and optical modules, the series offers densities as low as 8Mb in ultra-compact WLCSP packaging. This ensures superior storage performance within extremely limited physical footprints, facilitating lightweight industrial designs.
Exceptional Power Performance and Reliability
The GD25UF series delivers exceptional performance and power efficiency. It supports Single, Dual, Quad, and DTR Quad SPI modes, with a maximum clock frequency of 120MHz in STR mode and 80MHz in DTR mode, achieving a high data throughput of up to 80MB/s, and it also supports two operating modes: normal mode and low power mode. Compared to traditional 1.8V Flash, its operating voltage is reduced by approximately 33%, cutting power consumption by 50% to 70%. This is critical for health monitoring and battery-powered IoT devices, significantly extending battery life.
Furthermore, the series offers high reliability with 100,000 program/erase cycles and 20-year data retention. With operating temperatures ranging from -40℃~85℃, -40℃~105℃ and -40℃~125℃, it meets rigorous standards for industrial and automotive applications.
The full GD25UF series is now in mass production with multiple packages offer, including SOP8, WSON8, USON8 and WLCSP. For samples or technical support, please contact GigaDevice sales representatives or authorized distributors.
