Product details
Overview
W25Q16JWUXIQ TR from Winbond is a 1.8V, 16M-bit (2MB) serial flash memory IC supporting Dual/Quad SPI, QPI, and DTR read modes. It delivers up to 133MHz Quad I/O clocking, enabling 66MB/s continuous data transfer, and features uniform 4KB sectors for flexible code and data storage in space-constrained embedded systems.
For engineers reviewing the W25Q16JWUXIQ TR datasheet, W25Q16JWUXIQ TR pinout, W25Q16JWUXIQ TR application, or W25Q16JWUXIQ TR equivalent, key selection considerations include its 1.65–1.95V supply range, JEDEC-compliant SFDP register, 64-bit unique ID, hardware write-protect (/WP), hold (/HOLD), and configurable /RESET functionality on 8-pin packages.
Technical Context
The W25Q16JWUXIQ TR implements a quad-peripheral interface (QPI) mode entered via 38h instruction, reducing instruction overhead by transmitting opcodes across all four IO lines in two clocks instead of eight. Its non-volatile Quad Enable (QE) bit in Status Register-2 must be set to activate IO2 (/WP) and IO3 (/HOLD) for Quad SPI operation.
It supports erase/program suspend/resume, volatile and non-volatile status register bits (BP2–BP0, TB, SEC, CMP, SRP), and three 256-byte security registers with OTP locks. The device operates in Standard SPI (Mode 0/3), Dual SPI, Quad SPI, and QPI - mutually exclusive modes controlled by instruction sequence and register state.

Pinout & Package
W25Q16JWUXIQ TR is supplied in an 8-pad USON 2×3-mm package (package code UX), with exposed pad for thermal dissipation and compact board footprint.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| /CS | Chip Select Input | Active-low enable; places DO/IO pins in high-Z when deasserted; required to transition high→low after power-up before first instruction |
| DO (IO1) | Data Output / Bidirectional I/O1 | Unidirectional output in Standard SPI; bidirectional I/O in Dual/Quad SPI/QPI; used with IO0 for dual-speed reads |
| /WP (IO2) | Write Protect Input / Bidirectional I/O2 | Hardware lock for status register when QE=0; becomes IO2 in Quad SPI/QPI when QE=1 |
| GND | Ground Reference | Primary return path for VCC and signal currents; requires low-impedance connection to minimize noise coupling |
| DI (IO0) | Data Input / Bidirectional I/O0 | Unidirectional input in Standard SPI; bidirectional I/O in Dual/Quad SPI/QPI; carries instructions, addresses, and data |
| CLK | Serial Clock Input | Edge-triggered timing reference for all SPI/QPI transfers; supports Mode 0 and Mode 3 polarity/phase configurations |
| /HOLD or /RESET (IO3) | Hold or Reset Input / Bidirectional I/O3 | Pauses active operation when /CS is low (Hold); or resets internal state (Reset) - function selected via Status Register when QE=0 |
| VCC | Power Supply | 1.65–1.95 V core supply; decoupling capacitor (≥100 nF) required near pin for stable high-speed operation |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar serial flash memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MX25L1633FZUI-10G | 1.8V, 16Mb, supports DTR but lacks QPI mode; no 64-bit unique ID or security registers | Suitable for cost-sensitive consumer devices where QPI and security are not required | Choose when QPI acceleration and cryptographic isolation are unnecessary and BOM cost is primary constraint |
| AT25SF161-UUN-T | 1.8V, 16Mb, includes SFDP and 64-bit ID but omits DTR support and has lower max Quad I/O clock (80MHz) | Better suited for legacy SPI controllers lacking DTR timing control logic | Prefer when system controller does not implement DTR timing or when JEDEC JESD216B v1.0 compliance is mandatory |
Compared with MX25L1633FZUI-10G and AT25SF161-UUN-T, the W25Q16JWUXIQ TR uniquely combines QPI mode, DTR read, 133MHz Quad I/O, and OTP-locked security registers - making it optimal for secure, high-throughput embedded boot and firmware storage where both speed and trust are design requirements.

FAQ
What is the package type and dimensions of the W25Q16JWUXIQ TR?
The W25Q16JWUXIQ TR uses an 8-pad USON (Ultra Thin Small Outline No-lead) package measuring 2 mm × 3 mm with an exposed thermal pad. This compact, leadless package supports automated reflow assembly and provides improved thermal performance over SOIC variants while minimizing PCB footprint - critical for wearables and ultra-dense modules where the W25Q16JWUXIQ TR is commonly deployed.
Does the W25Q16JWUXIQ TR support execute-in-place (XIP) operation?
Yes, the W25Q16JWUXIQ TR supports true XIP operation via Quad SPI and QPI modes, enabling microcontrollers to fetch and execute code directly from flash without copying to RAM. Its 133MHz Quad I/O clock and DTR read capability deliver sustained >60 MB/s throughput, reducing boot latency and memory overhead - a key advantage realized in real-world deployments of the W25Q16JWUXIQ TR across ARM Cortex-M and RISC-V platforms.
How is hardware write protection implemented on the W25Q16JWUXIQ TR?
The W25Q16JWUXIQ TR implements hardware write protection using the /WP pin (active-low) in conjunction with non-volatile status register bits (BP2–BP0, TB, SEC, CMP, SRP). When /WP is asserted and SRP=1, writes to protected sectors or the status register itself are blocked - even during power cycling. This dual-layer protection is confirmed in the datasheet's "Write Protection" section and is actively used in the W25Q16JWUXIQ TR to safeguard bootloader regions in safety-critical firmware stacks.
Can the /HOLD pin on the W25Q16JWUXIQ TR be used as a hardware reset input?
Yes - on 8-pin packages like the W25Q16JWUXIQ TR, the /HOLD pin is multiplexed with /RESET functionality. When the QE bit is 0, the Status Register controls whether the pin acts as /HOLD (default) or /RESET (via SR2[7]). This dual-mode behavior is documented in Section 3.6 and Figure 1a–c of the datasheet, and is leveraged in the W25Q16JWUXIQ TR to reduce pin count while retaining both bus arbitration and recovery capabilities.
What is the purpose of the SFDP register in the W25Q16JWUXIQ TR?
The SFDP (Serial Flash Discoverable Parameters) register in the W25Q16JWUXIQ TR is a standardized, read-only JEDEC JESD216-compliant table (accessed via 5Ah command) that describes device geometry, timing parameters, and feature support. It enables host drivers to auto-configure without hardcoded values - a verified capability used in Linux MTD and Zephyr RTOS drivers for the W25Q16JWUXIQ TR to ensure interoperability across silicon vendors and controller generations.
