概述
Description
Key points:
- Capacity and organization: 32 Mbit (4 MByte), typically organized as 4M × 8.
- Interface: SPI serial interface (CS, CLK, MOSI, MISO) with optional fast modes; some variants support dual/quad I/O modes.
- Operations: 256‑byte page programming; erase granularity includes 4 KB sectors, 64 KB blocks, and full‑chip bulk erase; fast read up to tens of MHz (commonly up to ~104 MHz).
- Features: read/write protection options, status register, power‑down and wake, and low‑power modes.
- Electricals and packaging: usually 2.7–3.6 V supply; 8‑pin package (SOP/SOIC); suffixes indicate packaging/temperature options.
- Applications: firmware storage, boot memory, data logging, and other non‑volatile storage needs in MCU systems.
Note: exact voltage ranges, temperature grade, and supported modes depend on the specific suffix variant; consult the datasheet for precise specs.
