Product details
Overview
W25Q16JWXHIM TR from Winbond is a 1.8V, 16M-bit 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 sector erase, 256-byte page programming, and hardware write protection via /WP and /HOLD pins - deployed in embedded boot code storage and firmware update systems.
For engineers reviewing the W25Q16JWXHIM TR datasheet, W25Q16JWXHIM TR pinout, W25Q16JWXHIM TR application, or W25Q16JWXHIM TR equivalent, key selection criteria include 1.65–1.95V supply compatibility, XSON 2x3-mm (XH) package footprint, Quad Enable (QE) bit configuration for IO3 reassignment, and DTR instruction support for high-throughput read operations in resource-constrained microcontroller designs.
Technical Context
The W25Q16JWXHIM 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 volatile/non-volatile status register bits including QE (Status Register-2), TB, BP2–BP0, and SUS for erase/program suspend/resume.
It integrates three 256-byte security registers with OTP locks, 64-bit unique ID, JEDEC-compliant manufacturer/device ID, and SFDP register for discoverable parameters. The /HOLD and /WP pins function as IO3 and IO2 respectively when QE=1, and are disabled in Quad/QPI modes - requiring explicit register initialization before switching modes.

Pinout & Package
W25Q16JWXHIM TR uses the XSON 2×3×0.4 mm 8-pad package (Package Code XH), optimized for space-constrained PCB layouts. Pin assignments match the SOIC/WSON pinout mapping per Winbond's specification, with shared I/O functionality dependent on Quad Enable (QE) status.
| 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 | Used as DO in Standard/Dual SPI; becomes IO1 in Quad/QPI mode when QE=1 |
| 3 /WP (IO2) | Write Protect Input / Bidirectional I/O | Hardware lock for status register; repurposed as IO2 in Quad/QPI mode when QE=1 |
| 4 GND | Ground Reference | Primary return path for VCC and all I/O signals; requires low-impedance PCB plane |
| 5 DI (IO0) | Data Input / Bidirectional I/O | Serial instruction/address input in Standard SPI; becomes IO0 in Dual/Quad/QPI modes |
| 6 CLK | Serial Clock Input | Edge-triggered timing reference; supports SPI Modes 0 and 3; critical for DTR timing alignment |
| 7 /HOLD (IO3) | Hold Input / Bidirectional I/O | Pauses active transfers; becomes IO3 in Quad/QPI mode when QE=1; not available on 8-pin packages in QPI |
| 8 VCC | Power Supply | 1.65–1.95V core supply; decoupling capacitor required within 1 cm of pad |
Key Features
| Feature | Design Value |
|---|---|
| DTR Read Support | Double Transfer Rate instructions (e.g., 0Dh, EDh) latch address/data on both CLK edges - doubles effective bandwidth without raising clock frequency |
| QPI Mode | Reduces instruction overhead: 2-clock instruction fetch (vs. 8-clock in SPI) - improves XIP efficiency in real-time MCU applications |
| Erase/Program Suspend | Allows interruption of long erase/program cycles to service higher-priority tasks - essential for deterministic RTOS-based firmware updates |
| Security Registers | Three 256-byte OTP-lockable registers store cryptographic keys or calibration data - prevents unauthorized readback or modification |
| Unique 64-bit ID | Factory-programmed serial number enables device-level traceability and secure provisioning in production firmware flashing |

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; max Quad SPI clock = 104MHz | No QPI instruction reduction benefit; lower max throughput (52MB/s vs. 66MB/s) | Choose when QPI mode is unused and cost sensitivity outweighs 20% speed loss |
| S25FL116K0XMFI041 | 1.8V, 16Mb, supports QPI and DTR, but only 85MHz Quad SPI clock (34MB/s) | Slower random access; no suspend/resume; fewer security register options | Prefer only if Cypress toolchain integration or specific SFDP parameter compatibility is required |
Compared with MX25L1633FZUI-10G and S25FL116K0XMFI041, the W25Q16JWXHIM TR delivers highest sustained read bandwidth, full QPI+DTR feature set, and integrated security registers - making it optimal for XIP-critical, update-intensive, and security-aware embedded systems where throughput and data integrity are co-prioritized.

FAQ
What is the package type and footprint of W25Q16JWXHIM TR?
W25Q16JWXHIM TR uses the XSON 2×3×0.4 mm 8-pad package (Package Code XH), with identical pinout to SOIC and WSON variants. Its compact footprint supports high-density PCB layouts in wearables, medical sensors, and miniaturized industrial controllers. The pad layout follows JEDEC MO-252 standards, and thermal pad is not included - simplifying assembly while maintaining thermal performance within 1.95V/85°C limits.
Does W25Q16JWXHIM TR support Quad Peripheral Interface (QPI) mode?
Yes, W25Q16JWXHIM TR supports QPI mode via the "Enter QPI (38h)" instruction after setting the non-volatile Quad Enable (QE) bit in Status Register-2. In QPI mode, all four IO pins carry instructions and data simultaneously, reducing instruction latency by 75% versus standard SPI. The /HOLD and /WP pins become IO3 and IO2, and standard SPI commands are disabled until "Exit QPI (FFh)" is issued.
How does the DTR (Double Transfer Rate) feature improve performance in W25Q16JWXHIM TR?
W25Q16JWXHIM TR implements DTR read instructions (e.g., 0Dh, EDh) that sample address and data on both rising and falling edges of CLK - doubling effective data rate without increasing clock frequency. This allows 66MB/s throughput at 133MHz, avoiding signal integrity issues associated with >133MHz routing while matching or exceeding parallel flash bandwidth in MCU boot scenarios.
Can W25Q16JWXHIM TR be used for secure firmware storage?
Yes, W25Q16JWXHIM TR includes three 256-byte security registers with OTP lock bits, a factory-programmed 64-bit unique ID, and configurable block/sector protection via BP/TB/SEC bits. These features enable cryptographic key storage, device binding, and tamper-resistant firmware partitioning - validated in Winbond's Secure Flash documentation and supported by industry-standard provisioning tools.
What is the minimum supply voltage and power-down current for W25Q16JWXHIM TR?
W25Q16JWXHIM TR operates from 1.65V to 1.95V, with typical power-down current of <0.1µA at +25°C. This ultra-low quiescent draw enables use in battery-backed systems such as smart meters and portable diagnostics, where multi-year shelf life and rapid wake-from-sleep response are required. The device maintains full functionality across the entire voltage range without performance derating.
