GigaDevice has introduced the GD25UF series of SPI NOR Flash in its strategic roadmap of 1.2-V Flash products supporting systems-on-chip (SoCs) and applications processors built on advanced process nodes. The GD25UF SPI NOR Flash products are optimized for applications that require ultra-low power consumption or a small board footprint.

The GD25UF products operate at a supply-voltage range of 1.14-V to 1.26-V. This is ideal for devices built on advanced process nodes and operating at a core voltage of 1.2-V, as it provides for a simpler power system architecture, and for direct interfacing between the I/O pins of the SoC or processor and the GD25UF device.

With the GD25UF products, GigaDevice provides better specifications than other competing 1.2-V products in the parameters that manufacturers of mobile communications devices, wireless modems and wearable devices care most about. Its low-power mode operates at a frequency of up to 50 MHz, and Active Read current can be as low as 0.4 mA at frequencies lower than 50 MHz. Deep power-down current of 0.1 µA makes the GD25UF ideal for any battery-powered or wearable application. In addition, industry-best program and erase times help increase device manufacturing throughput while reducing system power consumption.

In Fast Read mode, these Flash devices operate at up to 120 MHz and achieve a data-transfer rate of up to 480 Mbits/s. In low EMI mode, operating at 6 0MHz over a double transfer-rate (DTR) quad I/O interface, the GD25UF products achieve the same data-transfer rate of 480 Mbits/s while minimizing clock-generated noise, an ideal feature for noise-sensitive wireless applications.
The 64 Mbit GD25UF64E is in production now. It is supplied in SOP8, 3- x 4-mm or 4- x 4-mm USON8 and WLCSP packages, or as a known good die. The 128 Mbit GD25UF128E is sampling. Products with memory capacity of 32 Mbits and 256 Mbits are in development.

Syed S. Hussain, Flash BU Global Segment Marketing Director of GigaDevice said: “Users of chips manufactured at advanced process nodes require a new generation of low-voltage Flash memory products that are optimized for the demanding applications that they support, such as IoT devices, mobile phones, PCs and laptops, and consumer devices, e.g. portable healthcare, smart watch and battery-based devices. The launch of the GD25UF64E 1.2-V Flash product marks the start of a comprehensive roadmap of low-voltage Flash products from GigaDevice, providing OEMs with the mix of memory capacities, serial interfaces and security functions that they need for the next generation of system designs. There is a Megatrend, where one shrinks SoCs down to lowest process geometry a must requirement is peripherals needs to support 1.2-VIO also. GigaDevice is uniquely positioned to win ultra-low power and performance megatrend in new designs.”
