Product Attributes

Features

• SPI-compatible serial bus interface
• Single and double transfer rate (STR/DTR)
• Clock frequency – 133 MHz (MAX) for all protocols in STR – 90 MHz (MAX) for all protocols in DTR
• Dual/quad I/O commands for increased throughput up to 90 MB/s
• Supported protocols in both STR and DTR Extended I/O protocol – Dual I/O protocol – Quad I/O protocol
• Execute-in-place (XIP)
• PROGRAM/ERASE SUSPEND operations
• Volatile and nonvolatile configuration settings
• Software reset
• Additional reset pin for selected part numbers
• Dedicated 64-byte OTP area outside main memory – Readable and user-lockable – Permanent lock with PROGRAM OTP command
• Erase capability – Bulk erase – Sector erase 64KB uniform granularity – Subsector erase 4KB, 32KB granularity
• Security and write protection – Volatile and nonvolatile locking and software write protection for each 64KB sector – Nonvolatile configuration locking – Password protection – Hardware write protection: nonvolatile bits (BP[3:0] and TB) define protected area size – Program/erase protection during power-up – CRC detects accidental changes to raw data
