概述

Description

The W25Q16FWSNIQ is Winbond’s 16‑Mbit serial flash memory. It stores firmware and data for embedded systems and is accessed via a SPI-compatible interface (standard SPI; many variants also support Dual/Quad I/O modes).
Key points:
- Density: 16 Mbit (2 MB)
- Voltage: typically 2.7–3.6 V
- Addressing: 3-byte addressing (no 4-byte mode required at this density)
- Speed: fast read up to ~104 MHz; standard read slower
- Organization: 256-byte page program
- Erase: 4 KB sectors and larger blocks (e.g., 64 KB); full-chip erase option in some variants
- Features: write enable/in progress status, hardware write protection via WP#, low‑power modes and deep power‑down
- Package: 8‑pin package (SOP/SOIC or similar); suffix SNIQ denotes specific package/grade
Typical use: storing boot code, firmware updates, or configuration data in microcontroller projects.
Note: exact commands, timing, endurance, and quirks depend on the specific SNIQ variant—check the W25Q16FWSNIQ datasheet for the precise package/temperature grade details.

Features

W25Q16FWSNIQ features (concise):
- 16 Mbit (2 MB) serial flash memory, 3.3V supply (typically 2.7–3.6V).
- 3-byte addressing (no 4-byte needed for this capacity).
- SPI serial interface with support for Standard SPI, Dual SPI, and Quad I/O (QIO) modes.
- Fast read up to high-speed clock (up to ~104 MHz) in supported modes.
- Page program: 256-byte pages.
- Erase types: 4 KB sectors, 64 KB blocks, and chip erase.
- Low-power operation with deep power-down mode.
- Secure features: software/hardware write protection (BP bits, WP# pin), and JEDEC ID support.
- Data retention rated for long-term use; typical endurance on the order of 100k P/E cycles per sector.
- Temperature range: -40°C to +85°C (industrial) variants available.
- Packaging: 8-pin options (SOP/related packages) suitable for compact designs.
Note: Exact features may vary by package/voltage variant; verify against the specific datasheet revision for W25Q16FWSNIQ.

Package

8-pin SOP (SOP-8) surface-mount package.

Pinout

- Pin count: 8 pins (8-pin package, e.g., SOP/SOIC).
- Function: Winbond W25Q16FWSNIQ is a 16-Mbit serial flash memory accessed via a standard SPI interface (CS, SCK, SI, SO) with additional WP# (write protect), HOLD#, VCC, and GND pins for storage of firmware/data.

Manufacturer

- Manufacturer: Winbond Electronics Corp.
- What kind of company: A Taiwanese semiconductor company that designs and manufactures memory ICs (notably NOR/NAND flash and DRAM). It is a global supplier of memory products used in a wide range of electronics.

Application

W25Q16FWSNIQ is a 16-Mbit SPI/NOR flash memory. Common application areas:
