Alliance Memory AS5F Serial Peripheral Interface (SPI) NAND Flash

Alliance Memory AS5F Serial Peripheral Interface (SPI) NAND Flash are memory devices with Single-Level Cell (SLC) NAND of the standard parallel NAND. These devices operate from 1.8V to 3V with densities from 1Gb to 8Gb and high-speed clock frequencies up to 120MHz. The AS5F SPI NAND flash devices offer increased reliability, faster boot-up, and more than 60,000 write and erase cycles in a smaller form factor. These devices provide a low-cost and low pin count solution to alternate SPI-NOR in high-density, non-volatile memory storage solutions for embedded systems. The AS5F SPI NAND flash devices feature 64x pages of one-time programmable protection, where each page consists of a data storage region and a spare area. The data storage region stores user-programmed data, and the spare area is typically used for memory management and error correction functions. 

The AS5F SPI NAND flash device's enhanced performance meets the requirements for multimedia data storage applications and Artificial Intelligence (AI) implementation. These devices are ideal for use in chipsets for Wi-Fi routers, mobile devices, xDSL/xPON technologies, data cards, IP cameras, set-top boxes, digital TVs, smart home devices, and more. The SPI NAND flash devices operate from -40°C to +85°C and offer 25mA read/program currents and 30mA erase currents. The AS5F flash devices support standard, dual, and quad SPI operation and are provided in the lead (Pb)- and halogen-free LGA 8-pin package.
