Product details
Overview
W25Q16DVSNJP 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 architecture, and hardware write protection via /WP and /HOLD pins - deployed in embedded boot code storage, firmware update partitions, and XIP-capable microcontroller systems.
For engineers reviewing the W25Q16DVSNJP TR datasheet, W25Q16DVSNJP TR pinout, W25Q16DVSNJP TR application, or W25Q16DVSNJP TR equivalent, this page delivers verified package mapping (SOIC-8 150-mil), confirmed Quad SPI timing (416 MHz equivalent), JEDEC ID compliance, 64-bit unique serial number support, and real-world erase/program cycle endurance (100,000 cycles).
Technical Context
The W25Q16DVSNJP TR implements a SPI-compatible command set 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 internal architecture includes an 8,192-page array (256 bytes/page), 512 × 4 KB sectors, and 32 × 64 KB blocks, enabling flexible partitioning for code + data storage.
It integrates dual-level write protection: hardware-based via active-low /WP and /HOLD pins (disabled in Quad mode), and software-based via BP0–BP2, TB, SEC, CMP, and SRP bits. Power management supports 4 mA active current and <1 µA power-down, operating across –40°C to +85°C on a single 2.7–3.6 V supply.

Equivalent & Alternatives
The following parts are listed as comparable options for similar serial NOR flash applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MX25L1606EM1I-12G | Same density (16 M-bit), 3.3 V, SOIC-8; supports Dual/Quad SPI but lacks SFDP and 64-bit UID | No built-in parameter auto-discovery; requires manual driver tuning; no unique ID for device authentication | Preferred where cost sensitivity outweighs security and configurability needs |
| S25FL116K0XMFI011 | 16 M-bit, 3.0 V min, SOIC-8; includes HyperBus interface option and enhanced ECC, but slower max clock (80 MHz) | Lower throughput (320 MHz Quad equivalent); added ECC supports safety-critical logging but increases latency | Chosen for ASIL-B systems requiring error correction, not raw speed or UID-based provisioning |
Compared with MX25L1606EM1I-12G and S25FL116K0XMFI011, W25Q16DVSNJP TR delivers superior XIP efficiency via SFDP-driven driver initialization, deterministic 104 MHz timing, and cryptographically verifiable device identity - making it optimal for secure, high-speed embedded boot and update workflows.

FAQ
What is the package type and lead count of W25Q16DVSNJP TR?
W25Q16DVSNJP TR uses an 8-pin SOIC package with 150-mil width (package code SN), featuring gull-wing leads, 1.27 mm pitch, and JEDEC MS-012AC compliance. This variant is distinct from wider SOIC-208-mil or WSON variants - the 'SN' suffix confirms the 150-mil body width and standard lead form factor used in W25Q16DVSNJP TR.
Does W25Q16DVSNJP TR support Quad SPI operation out of the box?
No - W25Q16DVSNJP TR requires the Quad Enable (QE) bit in Status Register-2 to be set (via Write Status Register instruction) to activate Quad SPI mode. Until QE=1, pins /WP and /HOLD remain dedicated to hardware protection; after enabling, they become IO2 and IO3. This one-time configuration is persistent across power cycles.
How does the /WP pin function in W25Q16DVSNJP TR when Quad SPI is enabled?
In W25Q16DVSNJP TR, the /WP pin serves as hardware write protection for the status register in Standard and Dual SPI modes. When Quad SPI is enabled (QE=1), /WP is reassigned as IO2 and loses its protection function - software-based protection (BP/TB/SRP bits) must then be used exclusively for sector locking in W25Q16DVSNJP TR designs.
What is the significance of the 64-bit Unique ID in W25Q16DVSNJP TR?
The 64-bit Unique ID in W25Q16DVSNJP TR is factory-programmed and immutable, enabling device-specific cryptographic binding, secure firmware signing verification, and anti-counterfeiting in production. It is accessible via Read Unique ID Number (4Bh) instruction and used in W25Q16DVSNJP TR-based secure boot chains to prevent unauthorized firmware injection.
Can W25Q16DVSNJP TR operate across the full industrial temperature range?
Yes - W25Q16DVSNJP TR is rated for –40°C to +85°C operation per its datasheet specification, with validated DC/AC electrical characteristics, timing margins, and erase/program endurance across that range. This makes it suitable for deployment in uncontrolled environments such as factory automation controllers and outdoor telematics units using W25Q16DVSNJP TR.
