Serial Flash Applications
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 packag-
ing costs, saves board space and keeps system costs down.
Oering lower power consumption and fewer wires than Paral-
lel Flash, Serial SPI Flash is the ideal cost-ecient data transfer
solution. Serial SPI Flash-Specic Features
• Densities up to 16 MB
• Full SPI protocol compatibility
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-Specic Features
• 4-bit multiplexed I/O serial protocol
• > 300 Mbps sustained read
• Density: 4 Mb to 64 Mb
• Software parameter and overlay block locking
• Security ID
• Page mode programming
• Serial Flash Discoverable Parameters (SFDP)
• Automotive Grade 2 and 3 with PPAP support
