Product details
Overview
W25Q16DVDAIG from Winbond is a 16 M-bit (2 MB) serial NOR flash memory IC supporting Standard, Dual, and Quad SPI interfaces with 104 MHz clock capability, 4 KB uniform sector erase granularity, and XIP-ready continuous read mode. It operates from 2.7–3.6 V, draws 4 mA active current and <1 µA in power-down, and targets embedded code storage and firmware boot applications.
For engineers reviewing the W25Q16DVDAIG datasheet, W25Q16DVDAIG pinout, W25Q16DVDAIG application, or W25Q16DVDAIG equivalent, key selection considerations include Quad SPI enable (QE bit), hardware write protection via /WP and /HOLD pins, 4 KB sector flexibility for parameter storage, and compatibility with SPI Mode 0/3 timing requirements.
Technical Context
The W25Q16DVDAIG implements a SPI-compatible command set with dedicated instructions for Fast Read Dual I/O (BBh), Fast Read Quad I/O (EBh), and Word Read Quad I/O (E7h), enabling up to 416 MHz effective data throughput. Its internal architecture includes a 256-byte page buffer, sector/block erase logic, and dual status registers with non-volatile Quad Enable (QE) bit in Status Register-2.
It supports JEDEC-standard manufacturer/device ID (90h/9Fh), 64-bit unique serial number (4Bh), and SFDP register (5Ah) for discoverable parameters. Erase/program suspend/resume (75h/7Ah) and security registers (3×256-byte OTP-locked) provide robust firmware update and protection capabilities.

Pinout & Package
W25Q16DVDAIG is packaged in an 8-pin SOIC 208-mil (package code SS), with pin 1 = /CS, pin 2 = DO (IO1), pin 3 = /WP (IO2), pin 4 = GND, pin 5 = DI (IO0), pin 6 = CLK, pin 7 = /HOLD (IO3), pin 8 = VCC. All pins support standard SPI; /WP and /HOLD become IO2/IO3 in Quad SPI mode when QE=1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| /CS (Pin 1) | Chip Select Input | Active-low enable: places device in high-impedance state when high; required low-to-high transition after power-up to accept commands |
| DO / IO1 (Pin 2) | Data Output / Quad I/O Line 1 | Unidirectional output in Standard SPI; bidirectional I/O in Dual/Quad modes - carries read data or address bits |
| /WP / IO2 (Pin 3) | Hardware Write Protect / Quad I/O Line 2 | Active-low lock for status register; repurposed as IO2 in Quad SPI when QE=1 - disables hardware WP in that mode |
| GND (Pin 4) | Ground Reference | Primary return path for VCC and all I/O signals; must be low-impedance for stable SPI timing and noise immunity |
| DI / IO0 (Pin 5) | Data Input / Quad I/O Line 0 | Unidirectional input in Standard SPI; bidirectional I/O in Dual/Quad modes - carries instructions, addresses, and write data |
| CLK (Pin 6) | Serial Clock Input | Master-generated edge-triggered timing signal; supports SPI Mode 0 (CPOL=0, CPHA=0) and Mode 3 (CPOL=1, CPHA=1) |
| /HOLD / IO3 (Pin 7) | Hold Input / Quad I/O Line 3 | Pauses ongoing SPI transaction while /CS remains low; repurposed as IO3 in Quad SPI when QE=1 - disables HOLD in that mode |
| VCC (Pin 8) | Power Supply | Single 2.7–3.6 V supply; powers core logic, charge pumps, and I/O buffers - requires local 0.1 µF decoupling |
Key Features
| Feature | Design Value |
|---|---|
| Quad SPI with QE bit | Enables 4-line data transfer (IO0–IO3) for 4× bandwidth vs. Standard SPI - requires non-volatile QE=1 setting in Status Register-2 |
| Continuous Read Mode | Reduces instruction overhead to ≤8 clocks per 24-bit address - enables true execute-in-place (XIP) from flash without RAM copy |
| Erase/Program Suspend | Allows pausing long erase/write operations (75h) to service higher-priority reads - resumes with 7Ah - critical for real-time systems |
| 64-bit Unique ID | Factory-programmed serial number (4Bh instruction) - enables secure device authentication and firmware binding per unit |
| Security Registers | Three 256-byte OTP-locked regions (42h/44h/48h) - store cryptographic keys or calibration data immune to field reprogramming |
| SFDP Register | JEDEC JESD216-compliant parameter table (5Ah) - allows host bootloader to auto-detect timing, voltage, and feature support |

Equivalent & Alternatives
The following parts are listed as comparable options for similar serial NOR flash memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MX25L1606E | Same density (16 M-bit), 3.3 V, but max Quad SPI clock 80 MHz; no SFDP register; lacks security registers and unique ID | Suitable for cost-sensitive consumer devices where advanced security and auto-configuration are unnecessary | Choose MX25L1606E only if lower bandwidth (320 MB/s vs. 416 MB/s) and absence of OTP security features are acceptable |
| S25FL116K | 16 M-bit, 3.0 V min, supports HyperBus interface (not SPI); includes on-die ECC; different command set and QE implementation | Targeted at high-reliability applications requiring error correction and wider voltage margin, not SPI-only designs | Select S25FL116K only when HyperBus interface and built-in ECC are required - not a drop-in SPI replacement for W25Q16DVDAIG |
Compared with MX25L1606E and S25FL116K, W25Q16DVDAIG delivers higher Quad SPI bandwidth, JEDEC SFDP auto-discovery, and factory-programmed unique ID - making it optimal for secure, XIP-capable, and BSP-portable embedded systems where SPI compatibility and feature richness are prioritized over minimal BOM cost or ECC requirements.

FAQ
What is the package type and pin count of W25Q16DVDAIG?
W25Q16DVDAIG uses an 8-pin SOIC 208-mil package (package code SS). Its pinout includes /CS, DO/IO1, /WP/IO2, GND, DI/IO0, CLK, /HOLD/IO3, and VCC. The /WP and /HOLD pins serve dual roles: hardware protection in Standard/Dual SPI, and I/O lines IO2/IO3 in Quad SPI mode when the QE bit is set in Status Register-2.
Does W25Q16DVDAIG support execute-in-place (XIP) operation?
Yes, W25Q16DVDAIG supports true XIP via its Continuous Read Mode, which reduces instruction overhead to as few as 8 clock cycles per 24-bit address. When used with Fast Read Quad I/O (EBh) or Word Read Quad I/O (E7h) instructions, the device delivers up to 416 MB/s effective throughput - enabling direct code execution from flash without copying to RAM.
How is Quad SPI mode enabled on W25Q16DVDAIG?
Quad SPI mode on W25Q16DVDAIG is enabled by setting the non-volatile Quad Enable (QE) bit in Status Register-2 using the Write Status Register (01h) instruction. Once QE=1, the /WP and /HOLD pins become IO2 and IO3 respectively, completing the 4-line I/O interface. This configuration persists across power cycles unless explicitly cleared.
What security features does W25Q16DVDAIG provide?
W25Q16DVDAIG provides hardware write protection via /WP and /HOLD pins, programmable block/sector protection bits (BP2–BP0, TB, SEC), OTP-locked 3×256-byte security registers (accessible via 42h/44h/48h), and a factory-programmed 64-bit unique ID (readable with 4Bh). These features collectively support secure firmware updates, device authentication, and tamper-resistant parameter storage.
Can W25Q16DVDAIG be used in industrial temperature applications?
Yes, W25Q16DVDAIG is rated for operation from −40°C to +85°C and specified for 20-year data retention at +25°C. Its 2.7–3.6 V supply range, low 4 mA active current, and <1 µA power-down current make it suitable for unattended industrial equipment, remote sensors, and other extended-temperature embedded systems.
