The MT25Q is a high-performance multiple input/output serial Flash memory device. It features a high-speed SPI-compatible bus interface, execute-in-place (XIP) functionality, advanced write protection mechanisms, and extended address access. Innovative, high-performance, dual and quad input/output commands enable double or quadruple the transfer bandwidth for READ and PROGRAM operations.
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
• Electronic signature
– JEDEC-standard 3-byte signature (BA18h)
– Extended device ID: two additional bytes identify device factory options
• JESD47H-compliant
– Minimum 100,000 ERASE cycles per sector
– Data retention: 20 years (TYP)
