Winbond 1.2V Serial NOR Flash

The W25QxxND 1.2V series of Serial NOR Flash has performance identical to the popular 3V and 1.8V families of serial flash with the added benefit of saving power.

Packages offered:

2mm x 3mm USON8

narrow 150mil SOP8

6x5mm WSON 8-pin

KGD (Known Good Die)

The packages offered provide designers with the convenience of designs in space constrained battery based applications for mobile, wearable, IoT and other demanding designs that call for low power in tiny packages.

While the 1.2V series of Serial NOR Flash is popular for power savings, the extended 1.5V can save battery cost by utilizing only one battery compared to similar solutions using two batteries in series to offer 3V designs.

SpiFlash Family: The First Ultra-Low-Voltage

New 1.2V is the next standard voltage

The newest members of the Winbond SpiFlash family are the industry’s lowest voltage standard, dual and quad Serial Peripheral Interface (SPI) and Quad Peripheral Interface (QPI) Serial NOR Flash products offering major power savings not known in the industry before.

Better Power Consumption

Increase battery run-time / Power saving in active mode of 33%

The reduced power usage in both active and stand-by modes offered by the W25QxxND series of Serial NOR Flash enables system designers to increase battery run-time between charges, or to reduce the size and weight of the battery.

The W25Q80ND, an 8Mb NOR Flash IC operating from a 1.2V supply, offers a typical power saving in active mode of 33% over the equivalent 1.8V part.

Simplify The System Power Domain

Reduce power consumption by turning off NOR Flash while sleeping / Reduce system BOM cost by simple power domains

The new devices also provide additional advantages. The first is the power circuit which benefits from reduced noise coupling in the traces connecting the memory to the host SoC or processor, a direct result of the reduced power that they carry. This can help ease the requirement to implement noise mitigation measures such as shielding, and to improve the performance of noise-sensitive elements of the circuit.

The other principal advantage of the 1.2V Serial NOR devices is the potential, over time, to simplify the power circuit.

Winbond Code Storage Flash Memory

The Code Storage Flash Memory family consists of NOR, NAND and TrustME® Secure Flash Memories. Winbond is the #1 supplier of Serial Flash products in the industry and is the largest unit supplier of NOR flash memories. In this SpiFlash® family, products range in densities from 512Kb through 1Gb mostly in small 8-pin packages, in addition to 16-pin SOIC and 24-ball BGA packages at 3V and 1.8V with speeds up to 133MHz.

The SLC NAND flash memories are offered in densities from 1Gb through 4Gb in JEDEC standard packages and are compliant to the ONFi standard. As an extension to the SpiNOR family, Winbond offers QspiNAND flash products in 1Gb and 2Gb densities with special features like continuous read which facilitates fast data transfer between flash and DRAM on system designs. The QspiNAND products have built-in ECC and bad block management which simplifies the management of NAND. All of these flash products are available as KGD (Known Good Die) as well. A family of Multi Chip Package (MCP) NAND + DRAM products are also offered ranging from 1Gb through 4Gb densities at 1.8V primarily used in mobile and other applications.

With AEC-Q100, TS16949, ISO9001/14001, OHSAS18001 qualifications, flash memory products are available in Industrial grade and several of these products are qualified for Automotive grade. These products in the flash memory family are used in computer, communication, consumer, mobile, automotive and industrial applications.
