Product details
Overview
W25Q16JWUXIM TR from Winbond is a 1.8V, 16M-bit serial flash memory IC supporting Dual/Quad SPI, QPI, and DTR read modes. It delivers 66 MB/s continuous data transfer, features 4KB uniform sectors (512 total), 100K program-erase cycles, and operates across –40°C to +85°C for embedded code storage and XIP execution in space-constrained systems.
For engineers reviewing the W25Q16JWUXIM TR datasheet, W25Q16JWUXIM TR pinout, W25Q16JWUXIM TR application, or W25Q16JWUXIM TR equivalent, key selection criteria include Quad Enable (QE) bit configuration, /HOLD vs /RESET pin behavior in 8-pin packages, DTR timing compliance, and USON 2x3-mm footprint compatibility with high-density PCB layouts.
Technical Context
The W25Q16JWUXIM TR implements a flexible SPI-compatible interface with mode-selectable operation: Standard SPI (DI/DO), Dual SPI (IO0/IO1), Quad SPI (IO0–IO3), and QPI (all four IOs for instruction + data). Its architecture supports true execute-in-place (XIP) via continuous read with wrap and 8-clock address access latency.
Internal register control enables volatile/non-volatile write protection (BP2–BP0, TB, SEC, CMP), security register locking (LB1–LB3, SFDP lock), and configurable output drive strength (DRV1/DRV0). The /HOLD or /RESET function on Pin 7 is software-configurable only when QE = 0 - it reverts to IO3 in Quad/QPI modes per Status Register-2 settings.

Pinout & Package
W25Q16JWUXIM TR uses an 8-pad USON 2×3-mm package (Package Code UX), with wettable flank leads for automated optical inspection. Pin 1 is marked by a beveled corner; the package is RoHS-compliant and halogen-free.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 /CS | Chip Select Input | Active-low enable; must transition high→low after power-up before accepting instructions |
| 2 DO (IO1) | Data Output / Bidirectional I/O | Standard SPI output; becomes IO1 in Dual/Quad/QPI modes; high-impedance when /CS high |
| 3 /WP (IO2) | Write Protect Input / Bidirectional I/O | Hardware lock for status register; functions as IO2 when QE=1 (Quad/QPI active) |
| 4 GND | Ground Reference | Primary return path for all I/O and core logic; requires low-impedance PCB plane connection |
| 5 DI (IO0) | Data Input / Bidirectional I/O | Standard SPI input; becomes IO0 in Dual/Quad/QPI modes; latched on CLK rising edge |
| 6 CLK | Serial Clock Input | Edge-triggered timing reference; supports Mode 0 and Mode 3 SPI polarity/phase configurations |
| 7 /HOLD or /RESET (IO3) | Hold/Reset Input / Bidirectional I/O | Configurable via Status Register: /HOLD when QE=0; /RESET only if enabled and QE=0; IO3 when QE=1 |
| 8 VCC | Power Supply | 1.65–1.95 V supply; decoupling capacitor (100 nF) required within 3 mm of pin |
Key Features
| Feature | Design Value |
|---|---|
| DTR Read Support | Double Transfer Rate (DTR) enables address/data sampling on both clock edges - doubles effective bandwidth without raising fCLK |
| Quad Peripheral Interface (QPI) | Reduces instruction overhead: 2 clocks instead of 8 for command entry - critical for low-latency XIP performance |
| Erase/Program Suspend & Resume | Allows interruption of long erase/program operations to service higher-priority tasks - preserves state without data loss |
| 64-bit Unique ID | Factory-programmed immutable serial number - enables secure device authentication and firmware binding |
| Security Registers | Three 256-byte OTP-lockable registers - store cryptographic keys or calibration data with hardware-enforced write protection |
| SFDP Register Compliance | JEDEC JESD216-compliant Serial Flash Discoverable Parameters - enables automatic driver configuration in modern SoCs |

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 | 1.8 V, 16 M-bit, supports DTR but lacks QPI mode; max Quad SPI clock 80 MHz | No QPI instruction acceleration; lower bandwidth limits XIP performance in latency-sensitive UIs | Prefer when QPI is unused and cost sensitivity outweighs 33% bandwidth penalty |
| S25FL116K0XMFI041 | 1.8 V, 16 M-bit, includes HyperBus interface option; no DTR support; 100K P/E cycles | HyperBus offers higher bandwidth than SPI but requires dedicated controller; incompatible pinout | Select only if migrating to Cypress/Infineon ecosystem with HyperFlash-capable SoC |
Compared with MX25L1633FZUI-10G and S25FL116K0XMFI041, the W25Q16JWUXIM TR uniquely combines DTR, QPI, and 133 MHz Quad I/O in a USON 2x3-mm package - enabling highest SPI-based XIP throughput and smallest footprint for next-gen embedded boot memory.

FAQ
What is the package type and lead finish for W25Q16JWUXIM TR?
W25Q16JWUXIM TR uses an 8-pad USON 2×3-mm package (Package Code UX) with wettable flank leads and matte tin (Sn) lead finish. This package supports automated optical inspection and meets IPC/JEDEC J-STD-020 moisture sensitivity level 3 (MSL3) requirements for surface-mount assembly.
Does W25Q16JWUXIM TR support hardware reset functionality?
W25Q16JWUXIM TR supports hardware reset only when the Quad Enable (QE) bit in Status Register-2 is cleared (QE = 0), allowing Pin 7 to function as /RESET. When QE = 1, Pin 7 becomes IO3 and hardware reset is disabled. Software reset remains available via 66h + 99h instructions regardless of QE state.
How does the /HOLD pin behave in Quad SPI mode on W25Q16JWUXIM TR?
In Quad SPI mode (QE = 1), the /HOLD function is disabled on W25Q16JWUXIM TR because Pin 7 is reassigned as IO3. The /HOLD signal is only active in Standard and Dual SPI modes when QE = 0. Designers must ensure external logic does not assert /HOLD during Quad/QPI operation to avoid bus contention.
What is the significance of the DTR (Double Transfer Rate) feature in W25Q16JWUXIM TR?
The DTR feature in W25Q16JWUXIM TR allows address and data to be sampled on both rising and falling edges of the serial clock, effectively doubling data throughput without increasing clock frequency. This enables faster firmware verification and GUI asset loading while maintaining EMI compliance at lower fCLK.
Can W25Q16JWUXIM TR be used for secure key storage?
Yes - W25Q16JWUXIM TR includes three 256-byte Security Registers with one-time-programmable (OTP) lock bits (LB1–LB3). Once locked, these registers become read-only and immune to accidental or malicious overwrite, making them suitable for storing cryptographic keys, calibration constants, or device-unique identifiers.
