2. Multi-Mode High-Speed SPI Interface
Fully compatible with Single SPI, Dual I/O SPI, Quad I/O SPI, supports both STR (Single Transfer Rate) and DTR (Double Transfer Rate) modes:
- Max STR clock: 133 MHz
- Max DTR clock: 90 MHz
- Peak Quad SPI read throughput up to 90 MB/s, enables XIP (Execute-In-Place) direct firmware execution without RAM shadowing
- Dedicated hardware pins: /CS, SCK, IO0~IO3, /WP, /HOLD, /RESET for simplified PCB layout
- Program/erase suspend & resume function: allows urgent read operations to interrupt flash programming/erasing tasks
- Built-in software reset + hardware /RESET pin for reliable system recovery
3. Electrical Operating Characteristics
- Single supply voltage range: 2.7 V ~ 3.6 V (standard 3.3 V industrial logic rail)
- Typical read operating current: 15 mA
- Standby leakage current < 10 μA; deep power-down mode with sub-microamp draw for battery-powered IoT terminals
- Integrated high-voltage charge pump inside die; no external high-voltage rail required for programming or erasing
4. Multi-Layer Security & Write Protection
- Hardware lock via /WP pin to block all program/erase operations
- Software per-sector lock bits to protect arbitrary memory zones
- Global non-volatile lock bit to secure full chip against overwriting
- Optional password protection mechanism for advanced OEM data security
- Power-fail safeguard logic to avoid corrupted pages during unexpected voltage drop
