RoHS 10 Compliant
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.
技術參數
- SPI-compatible serial bus interface
- Single and double transfer rate (STR/DTR)
- Clock frequency
- 166 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
