W25N04KVZEIR in Winbond W25Q SPI NOR Flash Family
The W25N04KVZEIR belongs to Winbond's high-density Serial NAND Flash family, designed to bridge the gap between low-density SPI NOR and high-capacity parallel NAND. These 4G-bit (512MB) devices operate on a 3V supply and utilize a standard SPI interface, providing a cost-effective non-volatile storage solution for systems requiring larger code or data storage without the high pin-count overhead of traditional parallel NAND interfaces.
Variants in This Sub-Family
Variants within this 4Gb sub-family primarily differ by supply voltage (1.8V vs 3V) and package type, including WSON-8 or TFBGA-24 options. Additional variations involve temperature grade ratings, spanning from industrial (-40C to +85C) to automotive-qualified grades. Some specific part numbers may also denote different default security register settings or factory-programmed configuration bits for specific boot requirements.
