Product details
Overview
W25Q16DVZPJG TR 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-capable continuous read mode - deployed for code storage and execution in microcontroller boot loaders, IoT firmware images, and embedded HMI graphics assets.
For engineers reviewing the W25Q16DVZPJG TR datasheet, W25Q16DVZPJG TR pinout, W25Q16DVZPJG TR application, or W25Q16DVZPJG TR equivalent, key selection criteria include Quad SPI enable (QE bit), /WP and /HOLD dual-role behavior in Quad mode, 2.7–3.6 V single-supply operation, 4 mA active current, and SOIC-8 208-mil (package code SS) mechanical compatibility.
Technical Context
The W25Q16DVZPJG TR implements a SPI-compatible command-set architecture with three operational modes: Standard (DI/DO), Dual (IO0/IO1), and Quad (IO0–IO3), where Quad mode requires non-volatile QE bit setting in Status Register-2. Its block diagram integrates a 256-byte page buffer, sector/block erase logic, SFDP register, and three 256-byte security registers with OTP locks.
Functional operation relies on precise timing control of /CS, CLK, and bidirectional I/O pins; /WP and /HOLD revert to IO2 and IO3 respectively when QE=1, disabling hardware write protection during Quad SPI use. Erase suspend/resume, 64-bit unique ID, and JEDEC-compliant manufacturer/device ID support secure, traceable firmware deployment.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 16 M-bit (2,097,152 bytes), organized as 8,192 × 256-byte pages |
| SPI Clock Frequency | Up to 104 MHz - enables 416 MB/s effective throughput in Quad I/O mode |
| Erase Granularity | Uniform 4 KB sectors (512 total), 32 KB blocks (32), 64 KB blocks (16), full chip |
| Supply Voltage | 2.7 V to 3.6 V - compatible with 3.3 V logic systems without level shifting |
| Active Current | 4 mA typical at 104 MHz - supports low-power firmware fetch in battery-operated devices |
| Data Retention | 20+ years - ensures long-term reliability for industrial and automotive firmware storage |
| Endurance | 100,000 program/erase cycles per sector - suitable for field-upgradable firmware partitions |
Pinout & Package
W25Q16DVZPJG TR 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. Pin functions shift under Quad SPI mode when QE=1: /WP and /HOLD become IO2 and IO3.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| /CS (Pin 1) | Chip Select Input | Active-low enable: high-Z output and standby current when high; required high-to-low transition after power-up to accept commands |
| DO / IO1 (Pin 2) | Data Output / Bidirectional I/O | Unidirectional output in Standard SPI; becomes bidirectional IO1 in Dual/Quad mode - used for read data and status |
| /WP / IO2 (Pin 3) | Write Protect Input / Bidirectional I/O | Hardware lock for status register when QE=0; repurposed as IO2 in Quad mode - disables hardware WP if QE enabled |
| 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 / Bidirectional I/O | Unidirectional input in Standard SPI; becomes bidirectional IO0 in Dual/Quad mode - carries instructions, addresses, and write data |
| CLK (Pin 6) | Serial Clock Input | Edge-triggered timing reference for all SPI operations - supports Mode 0 and Mode 3; max 104 MHz frequency |
| /HOLD / IO3 (Pin 7) | Hold Input / Bidirectional I/O | Pauses ongoing SPI transfer when active-low while /CS is asserted; repurposed as IO3 in Quad mode - disables hold function if QE enabled |
| VCC (Pin 8) | Power Supply | Single 2.7–3.6 V supply - powers internal charge pumps for erase/program; decoupling capacitor required near pin |
Key Features
| Feature | Design Value |
|---|---|
| Quad SPI Enable (QE bit) | Non-volatile Status Register-2 bit enabling IO2/IO3 functionality - required before issuing Quad Read/Program commands |
| Continuous Read Mode | As few as 8 clocks to initiate address access - enables true execute-in-place (XIP) from SPI bus without external RAM buffering |
| Security Registers | Three 256-byte OTP-lockable registers - store cryptographic keys or calibration data resistant to reprogramming |
| 64-bit Unique ID | Factory-programmed serial number per device - supports secure device authentication and firmware binding |
| Erase/Program Suspend | Pause ongoing erase or program via 75h instruction - allows high-priority reads or writes without aborting long operations |
| SFDP Register | JEDEC-standard discoverable parameter table - enables automatic driver configuration without hard-coded timing values |

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 |
|---|---|---|---|
| MX25L1606EM2I-12G | Same density (16 M-bit), 3 V supply, but max SPI clock 80 MHz; no Quad I/O support - only Standard/Dual SPI | Lacks QE bit and IO2/IO3 functionality; cannot achieve 416 MB/s throughput or XIP with Quad mode | Select when Quad SPI is unnecessary and cost sensitivity outweighs performance needs |
| S25FL116K0XMFI041 | 16 M-bit, 3 V, supports Quad SPI up to 104 MHz, but uses different status register layout and lacks SFDP register | Requires custom driver initialization; no JEDEC-standard parameter discovery - increases porting effort | Select for Cypress-based designs already using FL-S family drivers and toolchains |
Compared with MX25L1606EM2I-12G and S25FL116K0XMFI041, W25Q16DVZPJG TR uniquely combines JEDEC SFDP auto-configuration, 64-bit unique ID, and OTP-secured registers - reducing firmware integration effort and enhancing device-level security in certified applications.

FAQ
What is the package type and pin count of W25Q16DVZPJG TR?
W25Q16DVZPJG TR uses an 8-pin SOIC package with 208-mil body width (package code SS). Its pinout includes /CS, DO/IO1, /WP/IO2, GND, DI/IO0, CLK, /HOLD/IO3, and VCC - fully compatible with standard SOIC-8 footprints and pick-and-place equipment.
Does W25Q16DVZPJG TR support Quad SPI mode out of the box?
No - W25Q16DVZPJG TR requires the Quad Enable (QE) bit in Status Register-2 to be set via Write Status Register (01h) instruction before Quad SPI commands (e.g., EBh, 6Bh) are accepted. Default power-on state has QE=0, limiting operation to Standard or Dual SPI until configured.
How does the /WP pin behave when Quad SPI is enabled on W25Q16DVZPJG TR?
When QE=1, the /WP pin on W25Q16DVZPJG TR is reassigned as IO2 and loses its hardware write-protection function. Software-based protection via status register BP bits remains active, but physical /WP assertion no longer blocks status register writes - design must account for this functional shift.
What is the purpose of the 64-bit Unique ID in W25Q16DVZPJG TR?
The 64-bit Unique ID in W25Q16DVZPJG TR is factory-programmed and read-only, providing cryptographically verifiable device identity. It enables secure firmware binding, anti-cloning measures, and traceability in regulated applications such as medical devices and utility meters.
Can W25Q16DVZPJG TR be used for Execute-in-Place (XIP) applications?
Yes - W25Q16DVZPJG TR supports true XIP via Continuous Read Mode with as few as 8 clock cycles overhead per address. When paired with a memory-mapped SPI controller (e.g., STM32 OCTOSPI), it enables direct CPU instruction fetch without intermediate RAM loading.
