Serial SPI Flash 25 Series Serial SPI Flash is a small, low-power Flash memory that features a Serial Peripheral Interface (SPI) and pin-for-pin compatibility with industry-standard SPI EEPROM devices. Its small footprint reduces ASIC controller pin count and packaging costs, saves board space and keeps system costs down. Offering lower power consumption and fewer wires than Parallel Flash, Serial SPI Flash is the ideal cost-efficient data transfer solution. Serial SPI Flash-Specifi c Features ■ Densities up to 16 Mb ■ Single footprint package up to 32 Mb ■ Full SPI protocol compatibility 10 Memory Products Serial Flash Applications ■ Home networking ■ HDTVs ■ Bluetooth ■ Wearable devices ■ DSL and cable modems ■ Tablets ■ Hard disk drives ■ Desktop PCs ■ Notebook PCs ■ Netbooks ■ Printers ■ Wireless LAN ■ Set-top boxes ■ LCD monitors ■ Digital radios Serial Quad I/O™ (SQI™) Flash 26 Series SQI Flash memory uses 4-bit multiplexed I/O serial protocol, boosts performance while maintaining the compact form factor of standard SPI Flash. SQI devices can be used in Quad, Dual or SPI mode so it is backward compatible with SPI devices. SQI Flash-Specifi c Features ■ 4-bit multiplexed I/O serial protocol ■ > 300 Mbps sustained read ■ Density: 4 Mb to 64 Mb ■ Software parameter and individual block locking ■ Security ID ■ Page mode programming ■ Serial Flash Discoverable Parameters (SFDP)
