W25Q32JVZPIM

W25Q32JVZPIM is a Winbond 32‑Mbit serial flash memory. It provides nonvolatile storage for microcontrollers and embedded systems with fast SPI access and low power.
Key points:
- Capacity: 32 Mbit (4 MB) of flash memory.
- Interface: standard SPI; supports dual/quad I/O (QPI/dual SPI) modes for higher throughput.
- Voltage: 2.7–3.6 V supply.
- Speed: up to around 104 MHz in SPI (higher in dual/quad modes per datasheet).
- Organization: pages (typically 256 bytes), with sectors (often 4 KB) and larger blocks for erasing.
- Operations: page program, sector/block erase, and chip erase; includes status/config registers.
- Features: hardware write protection (WP), HOLD, deep power-down, reset, and optional security/OTP regions.
- Endurance/retention: erase endurance on the order of 100k–1M cycles per sector; data retention typically >20 years.
- Package: 8‑pin package (suffix ZPIM indicates the package type).
Typical uses: firmware storage/boot ROM, firmware updates, and data logging in embedded systems. For exact timing and command set, refer to the official datasheet.
