Atlantik Elektronik presents the new high-speed QspiNAND Flash ICs from Winbond

More flexibility and an alternative to NOR memories

Planegg, August 17th, 2020

Atlantik Elektronik, provider of innovative embedded solutions, presents the new QspiNAND Flash ICs from Winbond, one of the world's leading suppliers of semiconductor memory solutions.

The industry’s first 1.8V, 512Mbits (64Mega Bytes) QspiNAND Flash from Winbond Electronics offers the right density for designers of New Cellular NB-IoT Modules.

According to WebFeet Research, an independent market research firm, the IoT will expands to 50 billion connected devices by 2020, Quad SPI-NAND adoption rate may increase 4-5 fold within a few years.

Winbond's 1.8V QspiNAND Flash is suitable for Automotive and IoT segments. NB-IoT is poised to grow in this new connected world with shipments that may reach 685M units worldwide by 2023.

Winbond is working closely with Qualcomm Technologies on the Memory components for the next-generation LTE Modem solutions for IoT applications.

Winbond expands its reach from traditional QSPI-NOR Flash to QSPI-NAND Flash, giving customers the flexibility to choose their Code Storage Feature-Set to expand with minimal cost. This is done by using the same 6-pin signals and QSPI command-set for SLC NAND Flash densities without compromising performance by utilizing the new Continuous READ feature at 104MHz Read Speed.

W25N QspiNAND Flash family devices are offered in space-saving 8-pin packages which was not possible in the past for typical SLC NAND Flash memory. W25N512GW is a 512M-bit memory array organized into 32,768 programmable pages of 2,112 bytes each. W25N512GW provides a new Continuous Read mode that allows for efficient access to the entire memory array with a single Read command that is ideal for code shadowing applications.

Clock speeds of 104MHz allow equivalent 416MHz (104MHz x 4) speed for Quad I/O performance when using the Fast Read Dual/Quad I/O instructions. To provide better NAND Flash memory manageability, an on-chip feature is provided to perform bad block management.

“Expanding the SpiFlash family to include QspiNAND Flash will benefit the NOR market and SLC NAND Flash conversion from both QSPI-NOR Flash and Parallel NAND Flash,” said Ottmar Flach, Managing Director Atlantik Elektronik. “Winbond jointly-developed this new 512Mb QspiNAND Flash in delivering high performance with cost-benefit in mindW, added Ottmar Flach.
