25X40ALS32 datasheet



The W25X10AL (1M-bit), W25X20AL (2M-bit), 25X40ALS32 (4M-bit) and W25X80AL (8M-bit) Serial Flash memories provide a storage solution for systems with limited space, pins and power. The 25X series offers flexibility and performance well beyond ordinary Serial Flash devices. They are ideal for code download applications as well as storing voice, text and data. The devices operate on a single 2.3V to 3.6V power supply with current consumption as low as 5mA active and 1µA for power-down. All devices are offered in space-saving packages.


1. Single and Dual Serial Peripheral Interface
2. Uniform 4KB erasable sectors & 32KB/64KB erasable blocks
3. 2048 pages (256 bytes), page program in 0.7mS (typ.)
4. Fast Read (0Bh), Fast Read Dual Output (3Bh) and Fast Read Dual I/O (BBh) instructions
5. Clock operation up to 104MHz (208MHz equivalent with Fast Read Dual Output)
6. 4mA active read current, 1µA power down current
7. -40° to +85°C Industrial temperature operating range
8. Electronic ID in Single or Dual I/O mode
9. Read Unique ID (4Bh) instruction
10. Hardware and software write protection for top or bottom blocks
