Product details
Overview
W25Q16JVUXIM TR from Winbond is a 16 M-bit (2 MB) serial NOR flash memory IC supporting Dual/Quad SPI, QPI, and DTR read modes, organized as 8,192 × 256-byte pages with uniform 4 KB sector erase granularity. It operates from 2.7 V to 3.6 V, supports up to 133 MHz SPI clock (532 MHz equivalent Quad I/O), and delivers 66 MB/s continuous read throughput - enabling execute-in-place (XIP) code execution in embedded microcontrollers and IoT boot loaders.
For engineers reviewing the W25Q16JVUXIM TR datasheet, W25Q16JVUXIM TR pinout, W25Q16JVUXIM TR application, or W25Q16JVUXIM TR equivalent, key selection considerations include its USON 2×3-mm (UX) package, quad I/O capability with non-volatile QE bit, hardware /WP and /HOLD pins (active-low, disabled in Quad mode), JEDEC-compliant SFDP register, and 100K program-erase cycles per sector for firmware storage in space-constrained industrial controllers.
Technical Context
The W25Q16JVUXIM TR implements a multi-mode serial interface: Standard SPI (4-wire), Dual SPI (IO0/IO1 bidirectional), Quad SPI (IO0–IO3), and QPI (all four IOs used for instruction + address + data). Its architecture includes volatile/non-volatile status registers (SR1–SR3), programmable block protection (BP2–BP0, TB, SEC), and three 256-byte one-time-programmable (OTP) security registers.
It supports DTR (Double Transfer Rate) read instructions across all modes - latching address and data on both clock edges - achieving higher effective bandwidth without increasing clock frequency. The device features hardware reset via dedicated /RESET (in TFBGA) or configurable /HOLD or /RESET pin (in 8-pin packages depending on QE state), and power-down current <1 µA (typ.) for low-power edge nodes.
Key Specifications

| Security Features | 64-bit unique ID, SFDP register, three 256-byte OTP security registers, and hardware write-protect (/WP) with top/bottom/complement lock |
Pinout & Package
W25Q16JVUXIM TR uses an 8-pad USON (Ultra Thin Small Outline No-lead) package measuring 2 mm × 3 mm × 0.6 mm (Package Code UX), optimized for high-density PCB layouts in portable and wearable electronics.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 /CS | Chip Select Input | Active-low enable; must transition high→low after power-up before first instruction; high-impedance DO when deasserted |
| 2 DO (IO1) | Data Output / Bidirectional I/O | Unidirectional output in Standard SPI; becomes IO1 in Dual/Quad/QPI modes; supports DTR read timing |
| 3 /WP (IO2) | Write Protect Input / Bidirectional I/O | Hardware lock for status register; repurposed as IO2 when QE=1 - disables hardware WP in Quad mode |
| 4 GND | Ground Reference | Primary return path for VCC and I/O signals; requires low-inductance connection for signal integrity |
| 5 DI (IO0) | Data Input / Bidirectional I/O | Unidirectional input in Standard SPI; becomes IO0 in Dual/Quad/QPI; carries instruction/address/data on rising CLK edge |
| 6 CLK | Serial Clock Input | Master-generated timing signal; supports Mode 0 and Mode 3 SPI; DTR reads sample on both edges |
| 7 /HOLD or /RESET (IO3) | Hold/Reset Input / Bidirectional I/O | Pauses ongoing operation when /CS active; becomes IO3 in Quad mode; /RESET function only available when QE=0 in 8-pin packages |
| 8 VCC | Power Supply | Single 2.7–3.6 V supply; decoupling capacitor required near pin for stable read/write margins |
Key Features
| Feature | Design Value |
|---|---|
| Quad Peripheral Interface (QPI) | Reduces instruction overhead by sending 8-bit opcodes in 2 clocks (vs. 8 in SPI), accelerating XIP startup and reducing CPU wait states |
| DTR Read Support | Enables double-data-rate sampling on CLK edges for address and data - boosts effective bandwidth without raising clock frequency or EMI |
| Erase/Program Suspend & Resume | Allows background operations (e.g., logging) to pause flash writes/erases and resume later - critical for real-time deterministic response |
| Individual Sector Lock | Per-sector (4 KB) hardware/software locking via 32-bit security register - prevents accidental overwrite of bootloader or calibration data |
| SFDP Register Compliance | JEDEC JESD216-compliant Serial Flash Discoverable Parameters - enables automatic driver configuration in Linux/RTOS bootloaders |
Applications
| Firmware Storage in MCU Bootloader | IoT Edge Device Configuration |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar serial NOR flash applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MX25L1606EM2I-12G | 16 M-bit, 104 MHz max clock, SOIC-8 only; no DTR or QPI support; lacks SFDP and unique ID | Limited to Standard/Dual SPI; unsuitable for high-speed XIP or automated driver discovery | Select when cost sensitivity outweighs speed/security needs and board layout accommodates SOIC-8 |
| S25FL116K0XMFI041 | 16 M-bit, 80 MHz max clock, supports Quad SPI and SFDP but no DTR or QPI; Cypress/Infineon legacy part | Lower throughput (≤32 MB/s); no hardware /HOLD or /RESET pin multiplexing; fewer security registers | Choose for legacy design continuity where existing drivers target Spansion-compatible command set |
Compared with MX25L1606EM2I-12G and S25FL116K0XMFI041, the W25Q16JVUXIM TR delivers 66 MB/s continuous read, DTR timing flexibility, QPI instruction efficiency, and stronger security - making it optimal for next-generation firmware storage where speed, configurability, and tamper resistance are prioritized.

FAQ
What is the package type and footprint of W25Q16JVUXIM TR?
W25Q16JVUXIM TR uses an 8-pad USON (Ultra Thin Small Outline No-lead) package measuring 2 mm × 3 mm × 0.6 mm (Package Code UX). It has a wettable flank profile for automated optical inspection and requires reflow soldering per J-STD-020. The pad layout matches standard USON-8 land patterns with 0.5 mm pitch, and no thermal pad is included.
Does W25Q16JVUXIM TR support execute-in-place (XIP) operation?
Yes, W25Q16JVUXIM TR supports true XIP operation via Continuous Read Mode with as few as 8 clocks of instruction overhead and Quad SPI or QPI interfaces. When configured with QE=1 and using Fast Read Quad I/O (EBh) or QPI instructions, it delivers up to 66 MB/s sustained read throughput - sufficient for direct code execution on ARM Cortex-M and RISC-V cores without copying to RAM.
How does the /WP and /HOLD pin behavior change in Quad SPI mode?
In W25Q16JVUXIM TR, the /WP and /HOLD pins become IO2 and IO3 respectively when the Quad Enable (QE) bit in Status Register-2 is set to 1. This means hardware write protection and hold functionality are disabled in Quad SPI mode. To retain /WP or /HOLD, QE must remain 0 - limiting interface to Standard or Dual SPI, or requiring software-managed protection instead.
What security features does W25Q16JVUXIM TR provide for firmware protection?
W25Q16JVUXIM TR provides multiple firmware protection layers: hardware /WP pin (when QE=0), non-volatile block protect bits (BP2–BP0, TB, SEC), 64-bit unique ID for device authentication, JEDEC SFDP register for verified driver initialization, and three 256-byte OTP security registers - each programmable once to store cryptographic keys or secure boot manifests.
Is W25Q16JVUXIM TR qualified for automotive or extended temperature applications?
W25Q16JVUXIM TR is rated for industrial temperature range (-40°C to +85°C) and is not AEC-Q100 qualified. For automotive applications requiring extended temperature (-40°C to +105°C) or qualification, Winbond offers the pin-compatible W25Q16JVSNIQ variant (SOIC-8, SS code) - but W25Q16JVUXIM TR itself is intended for industrial and commercial use only.
