Product details
Overview
W25Q16DVSNJG 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 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 update applications in microcontroller-based systems.
For engineers reviewing the W25Q16DVSNJG TR datasheet, W25Q16DVSNJG TR pinout, W25Q16DVSNJG TR application, or W25Q16DVSNJG TR equivalent, key selection criteria include Quad SPI enable (QE bit), 4 KB sector erase granularity, hardware write protection via /WP and /HOLD pins, and compatibility with SPI Mode 0/3 for host controller integration.
Technical Context
The W25Q16DVSNJG TR implements a unified SPI command set supporting Standard (DI/DO), Dual (IO0/IO1), and Quad (IO0–IO3) I/O modes, where Quad operation requires setting the non-volatile Quad Enable (QE) bit in Status Register-2. Its internal architecture includes a 256-byte page buffer, 512 erasable 4 KB sectors, and 32 erasable 64 KB blocks, enabling flexible firmware partitioning.
It integrates dual-level write protection: hardware control via active-low /WP and /HOLD pins (when QE=0), and software control via status register bits (BP2–BP0, TB, SEC, CMP, SRP0/SRP1). The device also features a 64-bit unique ID, SFDP register for discoverable parameters, and three 256-byte one-time-programmable security registers.

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 |
|---|---|---|---|
| MX25L1606EM1I-12G | Same density (16 M-bit), 3.3 V supply, but max SPI clock 80 MHz; no Quad I/O support - only Dual/Standard SPI | Lacks Quad SPI and Continuous Read Mode; lower bandwidth limits XIP performance in latency-sensitive UI rendering | Select when cost sensitivity outweighs speed needs and host lacks Quad SPI controller support |
| S25FL116K0XMFI041 | 16 M-bit, 3.0 V min supply, supports Quad SPI up to 104 MHz, but uses different status register layout and lacks SFDP register | Requires custom driver adaptation for status bit interpretation; no auto-discovery of timing parameters | Choose when migrating from Cypress portfolio and existing firmware already handles non-SFDP initialization |
Compared with MX25L1606EM1I-12G and S25FL116K0XMFI041, W25Q16DVSNJG TR delivers higher effective bandwidth via Quad I/O and simplifies host integration through standardized SFDP, while its uniform 4 KB sectors and integrated security registers better support secure, field-upgradable embedded systems.

FAQ
What is the package type and lead count of W25Q16DVSNJG TR?
W25Q16DVSNJG TR uses an 8-pin SOIC 150-mil (package code SN) with gull-wing leads and 1.27 mm pitch. This JEDEC MS-012AC-compliant package is optimized for automated PCB assembly and provides reliable thermal and electrical performance in industrial temperature ranges.
Does W25Q16DVSNJG TR support execute-in-place (XIP) operation?
Yes, W25Q16DVSNJG TR supports true XIP via its Continuous Read Mode, which reduces instruction overhead to as few as 8 clock cycles per 24-bit address. When combined with Quad SPI Fast Read instructions (e.g., EBh), it enables direct code execution from flash without RAM shadowing in compatible microcontrollers.
How is Quad SPI mode enabled on W25Q16DVSNJG TR?
Quad SPI mode on W25Q16DVSNJG TR 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, pins /WP and /HOLD become IO2 and IO3 respectively, completing the four-line I/O interface required for Quad operations.
What write protection mechanisms does W25Q16DVSNJG TR provide?
W25Q16DVSNJG TR offers dual-layer write protection: hardware-level via active-low /WP and /HOLD pins (when QE=0), and software-level via status register bits (BP2–BP0, TB, SEC, CMP, SRP0/SRP1). This allows selective locking of 4 KB sectors, top/bottom array regions, or the entire memory array against accidental or malicious writes.
Is W25Q16DVSNJG TR compatible with standard SPI Mode 0 and Mode 3?
Yes, W25Q16DVSNJG TR fully supports both SPI Mode 0 (CPOL=0, CPHA=0) and Mode 3 (CPOL=1, CPHA=1), ensuring interoperability with legacy and modern microcontroller SPI peripherals. The device's clock polarity and phase tolerance is explicitly validated in the datasheet's AC timing specifications.
