概要

Description

W25Q32DWZPIG is a Winbond 32‑Mbit (4 MB) Serial NOR Flash memory in an 8‑pin package. It provides non-volatile storage for embedded systems and firmware, accessed via SPI.
Key points:
- Density: 32 Mbit; SPI interface with standard, Dual I/O, and Quad I/O modes
- Voltage: 2.7–3.6 V
- Speed: Fast read up to ~104 MHz
- Operations: Page program up to 256 bytes; erase options include 4 KB sectors, 32 KB/64 KB blocks, and chip erase
- Features: Write enable/disable, status register, hold, write protection, and deep power-down with resume
- Addressing: 3-byte addressing (sufficient for 4 MB)
- Temp range: typically -40 to 85°C (industrial)
- Package: 8‑pin, RoHS/lead‑free (suffix ZPIG)
Common uses: boot ROM, firmware storage, data logging, and firmware updates in microcontroller-based designs.

Features

W25Q32DWZPIG features (concise):
- Capacity: 32 Mbit (4 MB) serial flash.
- Voltage: 2.7–3.6 V supply.
- Interface: SPI-compatible with Standard SPI, Dual I/O, Quad I/O, and QPI modes.
- Performance: High-speed access (up to 104 MHz in SPI mode; Quad/Dual I/O modes accelerate throughput).
- Organization: 4,194,304 bytes; 256-byte page size; 4 KB sectors; 64 KB blocks; supports chip erase.
- Programming: Page Program (up to 256 bytes); random read/write with typical timing suited for fast boot/code storage.
- Power: Deep Power-Down mode and fast wake-up; low standby current.
- Security/protection: Status register with BP protection, WP# for sector protection, hardware write protection.
- Reliability: Endurance ~100,000 P/E cycles; data retention around 20 years.
- Temperature: Industrial range, typically -40°C to 85°C.
Optional note: Packaging available in common 8-pin configurations.

Package

8-pin SOP (SOIC-8) package.

Pinout

- Pin count: 8 pins (8-pin package, e.g., SOIC)
- Function: Non-volatile 32-Mbit serial flash memory (Winbond W25Q32DW) with SPI-compatible interface (supports standard SPI and dual/quad I/O modes on the DW family). Typical pinout: CS#, CLK, DI/DQ0, DO/DQ1, WP#, HOLD#, VCC, GND.
