Winbond introduces blazing fast 1Gbit serial NAND flash IC for automotive market
Winbond Electronics Corporation, a leading global supplier of semiconductor memory solutions, has announced the introduction of a High-Performance Serial NAND Flash memory IC. The company introduces a new W25N01JW NAND Flash IC which offers reliable, lower-cost alternative to SPI NOR Flash in 1Gbit and 2Gbit capacities for automotive displays and instrument clusters.
The new High-Performance Serial NAND technology offers a new high data-transfer rate of 83 MB/s via a Quad Serial Peripheral Interface (QSPI) and also supports a two-chip dual quad interface which gives a maximum data transfer rate of 166 MB/s. By raising the data transfer rate of its serial NAND technology to 83 MB/s – matching the read speed of automotive SPI NOR Flash – Winbond has ensured that the W25N01JW can support fast boot operation and the demanding requirements of sophisticated graphics applications.
The new W25N01JW chip can replace SPI NOR Flash memory in automotive applications such as data storage for instrument clusters or the Center Information Display (CID) because new flash’s high-speed Read operation is four times faster than the speeds that current serial NAND memory devices.
The advantages of new NAND Flash are important for automotive OEMs. The adoption of more sophisticated graphics displays in the instrument cluster, and larger display sizes of 7" and above in the CID, is increasing system memory requirements to capacities of 1Gbit and higher and new W25N01JW NAND Flash IC can provide it.
Other advantages of new serial NAND Flash are lower unit cost and a smaller board area per Mbit of storage capacity.
The high read speed of SPI NOR Flash supports the fast boot requirements of automotive user interfaces, and high reliability and long data retention. All this make it the preferred memory technology in automotive displays for many years.
