Dual/quad I/O instruction provides increased
throughput up to 432 MHz
Supported protocols
– Extended SPI, dual I/O, and quad I/O
Execute-in-place (XIP) mode for all three protocols
– Configurable via volatile or nonvolatile registers
– Enables memory to work in XIP mode directly af-
ter power-on
PROGRAM/ERASE SUSPEND operations
Continuous read of entire memory via a single com-
mand
– Fast read
– Quad or dual output fast read
– Quad or dual I/O fast read
Flexible to fit application
– Configurable number of dummy cycles
– Output buffer configurable
Software reset
64-byte, user-lockable, one-time programmable
(OTP) dedicated area
Erase capability
– Subsector erase 4KB uniform granularity blocks
– Sector erase 64KB uniform granularity blocks
– Full-chip erase
• Write protection
– Software write protection applicable to every
64KB sector via volatile lock bit
– Hardware write protection: protected area size
defined by five nonvolatile bits (BP0, BP1, BP2,
BP3, and TB)
– Additional smart protections, available upon re-
quest
• Electronic signature
– JEDEC-standard 2-byte signature (BB17h)
– Unique ID code (UID): 17 read-only bytes, in-
cluding:
• Two additional extended device ID (EDID)
bytes to identify device factory options
• Customized factory data (14 bytes)
• Minimum 100,000 ERASE cycles per sector
• More than 20 years data retention
• Packages JEDEC standard, all RoHS compliant
– F6 = V-PDFN-8 6mm x 5mm (MLP8 6mm x 5mm)
– F8 = V-PDFN-8 8mm x 6mm (MLP8 8mm x 6mm)
– 12 = T-PBGA-24b05 6mm x 8mm
– SF = SOP2-16 300 mils body width (SO16W)
– SE = SOP2-8 208 mils body width (SO8W)
– 53 = XF-SCSP-8/2.93mm x 3.5mm (XFCSP)
