Product details
Overview
W25Q16JVUUIM TR from Winbond is a 16 M-bit (2 MB) serial NOR flash memory IC supporting Standard/Dual/Quad SPI, QPI, and DTR read modes. It delivers up to 133 MHz clock frequency, 532 MHz equivalent Quad I/O throughput, and true execute-in-place (XIP) capability for embedded code storage. Its 4 KB uniform sector architecture, 100K program-erase cycles, and -40°C to +85°C operation make it suitable for boot code storage in microcontroller-based industrial controllers.
For engineers reviewing the W25Q16JVUUIM TR datasheet, W25Q16JVUUIM TR pinout, W25Q16JVUUIM TR application, or W25Q16JVUUIM TR equivalent, key selection considerations include Quad Enable (QE) bit configuration, /HOLD vs /RESET pin behavior in 8-pin packages, DTR timing compliance, and JEDEC SFDP register support for auto-configuration.
Technical Context
The W25Q16JVUUIM TR implements a flexible multi-mode serial interface: Standard SPI (4-wire), Dual SPI (IO0/IO1 bidirectional), Quad SPI (IO0–IO3), and QPI (all four IOs for instruction + data). QPI mode reduces instruction overhead to 2 clocks per byte versus 8 in standard SPI, enabling efficient XIP in resource-constrained systems.
Its memory array comprises 8,192 × 256-byte pages organized into 512 erasable 4 KB sectors and 32 × 64 KB blocks. Erase/suspend/resume functionality, volatile/non-volatile status register bits (BP2–BP0, TB, SEC, QE), and three 256-byte OTP-locked security registers provide robust firmware integrity control.

| 3 /WP (IO2) | Write Protect Input / Bidirectional I/O | Hardware write protection for status register when QE=0; becomes IO2 in Quad modes (QE=1) |
| 4 GND | Ground Reference | Primary signal return path; must be low-impedance connection to system ground plane |
| 5 DI (IO0) | Data Input / Bidirectional I/O | Unidirectional input in Standard SPI; becomes IO0 in Dual/Quad SPI/QPI; required for all instruction entry |
| 6 CLK | Serial Clock Input | Edge-triggered timing reference; supports Mode 0 and Mode 3; max 133 MHz frequency |
| 7 /HOLD or /RESET (IO3) | Hold or Reset Input / Bidirectional I/O | Pauses ongoing operation when /CS active (QE=0); becomes IO3 in Quad modes (QE=1); dedicated /RESET only in TFBGA |
| 8 VCC | Power Supply | Single 2.7–3.6 V supply; typical active current 15 mA, power-down current <1 µA |
Key Features
| Feature | Design Value |
|---|---|
| Quad Peripheral Interface (QPI) | Reduces instruction overhead from 8 to 2 clocks per byte, accelerating XIP startup and reducing CPU wait states |
| DTR Read Support | Latches address and data on both rising/falling CLK edges - doubles effective bandwidth without raising clock frequency |
| Uniform 4 KB Sector Architecture | Enables fine-grained firmware partitioning (e.g., bootloader + app + config), minimizing erase wear during field updates |
| Volatile & Non-Volatile Status Register Bits | BP2–BP0, TB, SEC, QE, and WPS allow persistent or runtime-configurable memory protection schemes |
| Three 256-Byte Security Registers | OTP-lockable storage for cryptographic keys or calibration data - isolated from main array and inaccessible via standard read |
| JEDEC SFDP Register | Provides standardized, vendor-agnostic parameter discovery - eliminates hardcoded timing values in host drivers |

Equivalent & Alternatives
The following parts are listed as comparable options for similar serial NOR flash applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MX25L1606EZN-12G | 16 M-bit, 104 MHz max clock, no QPI or DTR support; SOIC-8 only; lacks SFDP and security registers | Suitable for cost-sensitive, non-XIP designs where 66 MB/s throughput and firmware security are not required | Select when QPI/DTR and security features are unnecessary and SOIC-8 footprint is mandatory |
| S25FL116K10BAV101 | 16 M-bit, 80 MHz max clock, supports QPI but no DTR; includes HyperBus interface option; different status register layout | Better suited for Cypress/PSoC ecosystems; requires driver adaptation due to non-standard QE and BP bit mapping | Choose when migrating within Infineon/Cypress platforms or when HyperBus compatibility is needed |
Compared with MX25L1606EZN-12G and S25FL116K10BAV101, the W25Q16JVUUIM TR uniquely combines 133 MHz DTR throughput, JEDEC SFDP auto-configuration, and OTP-secured registers - making it optimal for new industrial and medical designs demanding performance, interoperability, and firmware integrity.

FAQ
What is the package type and footprint of W25Q16JVUUIM TR?
W25Q16JVUUIM TR uses an 8-pad USON package measuring 4 mm × 3 mm (Package Code UU), with exposed pad thermal design and RoHS-compliant matte tin finish. Its land pattern matches JEDEC MO-252 standards, and it is pin-compatible with other Winbond W25Q16JV variants in the same USON 4×3-mm form factor - including W25Q16JVUXIM TR and W25Q16JVEUIG TR.
Does W25Q16JVUUIM TR support Quad Peripheral Interface (QPI) mode?
Yes, W25Q16JVUUIM TR supports QPI mode via the "Enter QPI (38h)" instruction, but only after setting the non-volatile Quad Enable (QE) bit in Status Register-2. In QPI mode, all four IO pins (IO0–IO3) carry both instructions and data, reducing instruction latency from 8 to 2 clock cycles - a critical advantage for execute-in-place (XIP) applications requiring minimal CPU wait states.
How does the /HOLD pin function differ between Standard SPI and Quad SPI modes on W25Q16JVUUIM TR?
In Standard SPI mode (QE = 0), Pin 7 functions as /HOLD - pausing ongoing operations while /CS is active. In Quad SPI mode (QE = 1), Pin 7 becomes IO3 and the /HOLD function is disabled. For hardware reset capability in 8-pin packages, the /RESET function must be enabled via Status Register configuration before QE is set; otherwise, only software reset (66h + 99h) is available.
What security features does W25Q16JVUUIM TR provide for firmware protection?
W25Q16JVUUIM TR provides multiple firmware protection layers: hardware /WP pin locking, non-volatile block protect (BP2–BP0) and top/bottom (TB) bits, individual sector lock (36h/39h), three 256-byte OTP-locked security registers, and a 64-bit unique ID. These features collectively enable secure boot validation, anti-tampering, and cryptographic key storage - meeting IEC 62443-3-3 and UL 60730 requirements for industrial firmware integrity.
Is W25Q16JVUUIM TR compatible with JEDEC Standard Serial Flash Discoverable Parameters (SFDP)?
Yes, W25Q16JVUUIM TR implements the JEDEC JESD216B SFDP register, accessible via instruction 5Ah. This allows host controllers to automatically detect timing parameters, erase block sizes, and feature support - eliminating hardcoded driver assumptions and enabling plug-and-play compatibility across different flash vendors and densities in scalable product families.
