Product details
Overview
W25Q16DWZPIG TR from Winbond is a 1.8V, 16M-bit (2MB) serial NOR flash memory supporting Standard/Dual/Quad SPI and QPI interfaces, organized into 8,192 × 256-byte pages with uniform 4KB sector erase capability. It delivers up to 104MHz SPI clock rate, 50MB/s continuous read throughput, and operates across –40°C to +85°C for embedded code storage and XIP execution in space-constrained microcontroller systems.
For engineers reviewing the W25Q16DWZPIG TR datasheet, W25Q16DWZPIG TR pinout, W25Q16DWZPIG TR application, or W25Q16DWZPIG TR equivalent, key selection criteria include Quad Enable (QE) bit configuration, /WP and /HOLD dual-role behavior in Quad mode, 1.65–1.95V supply tolerance, JEDEC ID (EF4015), and 4KB sector granularity for firmware partitioning and OTA update resilience.
Technical Context
The W25Q16DWZPIG TR implements a flexible SPI command architecture with mode-exclusive operation: Standard/Dual/Quad SPI and QPI are mutually exclusive, requiring explicit Enable QPI (38h) or Disable QPI (FFh) instructions. Its status register includes non-volatile Quad Enable (QE) bit in SR-2, which reassigns /WP and /HOLD to IO2/IO3 only when set - disabling hardware write protection during Quad I/O use.
It supports multi-level erase granularity (4KB sector, 32KB/64KB block, full chip), Erase/Program Suspend & Resume (75h/7Ah), and four 256-byte Security Registers with OTP locks. The device uses internal high-voltage generators for program/erase, eliminating external VPP, and features a 64-bit unique serial number readable via 4Bh instruction.

Pinout & Package
W25Q16DWZPIG TR is supplied in an 8-pin WSON 6×5-mm package (JEDEC MO-241AC, package code ZP), with wettable flank leads for automated optical inspection. Pin functions are shared across SPI modes: /CS, CLK, DI (IO0), DO (IO1), /WP (IO2), /HOLD (IO3), VCC, GND.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| /CS (Pin 1) | Chip Select Input | Active-low enable; places DO/IO pins in high-Z when deasserted; required low-to-high transition before first instruction post-power-up |
| DO / IO1 (Pin 2) | Data Output / Bidirectional I/O | Unidirectional output in Standard SPI; bidirectional in Dual/Quad/QPI; used for status/data reads on falling CLK edge |
| /WP / IO2 (Pin 3) | Write Protect Input / Bidirectional I/O | Hardware write lock for status registers when QE=0; becomes IO2 in Quad/QPI mode (QE=1), disabling physical WP |
| GND (Pin 4) | Ground Reference | Primary return path for VCC and all I/O signals; requires low-inductance connection for noise immunity during fast reads |
| DI / IO0 (Pin 5) | Data Input / Bidirectional I/O | Unidirectional input in Standard SPI; bidirectional in Dual/Quad/QPI; accepts instructions/addresses/data on rising CLK edge |
| CLK (Pin 6) | Serial Clock Input | Master-generated timing signal; supports SPI modes 0 and 3; must be stable before /CS assertion |
| /HOLD / IO3 (Pin 7) | Hold Input / Bidirectional I/O | Pauses ongoing transfer while /CS active; becomes IO3 in Quad/QPI mode (QE=1), disabling hardware HOLD |
| VCC (Pin 8) | Power Supply | 1.65–1.95V core supply; decoupling capacitor (≥1µF ceramic) required within 5mm of pin for stable 104MHz operation |
Key Features
| Feature | Design Value |

| Quad Peripheral Interface (QPI) | Reduces instruction overhead from 8 clocks to 2 clocks per command, enabling deterministic XIP latency in real-time systems |
| Continuous Read Mode | Supports 8/16/32/64-byte wrap with ≤8-clock address setup - eliminates inter-byte gaps for streaming code execution |
| Erase/Program Suspend & Resume | Allows background interrupt servicing during long erase cycles (e.g., 4KB sector erase ~300ms), preserving system responsiveness |
| Security Register Locks | Four 256-byte OTP-locked security registers - isolate cryptographic keys or calibration data from firmware updates |
| Top/Bottom Block Protection | Configurable via TB and BP bits to protect boot code in lower sectors or application data in upper sectors independently |
| JEDEC Manufacturer ID | 0xEF (Winbond); Device ID 0x4015 - enables automatic flash detection and driver initialization in bootloader software |

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 | 3V supply (2.7–3.6V); no QPI mode; JEDEC ID EF4015 identical but lacks Octal Word Read (E3h) | Requires level-shifting for 1.8V systems; unsuitable for QPI-based XIP designs needing minimal instruction overhead | Select only if legacy 3V design reuse is mandatory and Quad SPI suffices |
| S25FL116K0XMFI041 | 1.8V supply; 16Mb density; supports HyperBus interface (not SPI/QPI); different command set and security model | Not drop-in compatible - requires HyperFlash controller IP and revised bootloader; higher pin count (16-pin SOIC) | Choose only when migrating to Cypress/Infineon ecosystem with HyperBus MCU support |
Compared with MX25L1606EM2I-12G and S25FL116K0XMFI041, the W25Q16DWZPIG TR uniquely balances 1.8V operation, QPI instruction efficiency, and 4KB sector flexibility - making it optimal for new 1.8V microcontroller designs requiring fast, secure, and field-upgradable code storage without interface redesign.

FAQ
What is the function of the /WP and /HOLD pins on the W25Q16DWZPIG TR in Quad SPI mode?
In Quad SPI mode, the /WP and /HOLD pins of the W25Q16DWZPIG TR become IO2 and IO3 respectively - this reassignment occurs only when the non-volatile Quad Enable (QE) bit in Status Register-2 is set to '1'. As a result, hardware write protection and hold functionality are disabled in Quad mode, and these pins serve exclusively as bidirectional data lines. Designers must rely on software-based status register protection (SRP0/SRP1) for write locking when using Quad I/O.
Does the W25Q16DWZPIG TR support execute-in-place (XIP) operation, and what conditions are required?
Yes, the W25Q16DWZPIG TR supports true XIP operation via Continuous Read Mode and QPI interface. For reliable XIP, the host MCU must support Quad SPI or QPI bus mastering, the QE bit must be set for Quad mode, and the flash must be configured with appropriate dummy cycles and latency settings per operating frequency. The device's ≤8-clock address setup and 50MB/s sustained read rate enable deterministic instruction fetch without local RAM buffering.
How many erase cycles can the W25Q16DWZPIG TR endure, and how is endurance distributed across the memory array?
The W25Q16DWZPIG TR guarantees ≥100,000 program/erase cycles per individual 4KB sector. Endurance is uniform across all 512 sectors - no wear-leveling controller is integrated, so system-level firmware must implement logical-to-physical mapping if cyclic writes target fixed addresses. The device does not degrade sector-by-sector; failure occurs only after exceeding cycle limits in specific sectors, making it suitable for parameter storage with managed write distribution.
What unique identification capability does the W25Q16DWZPIG TR provide, and how is it accessed?
The W25Q16DWZPIG TR provides a factory-programmed, globally unique 64-bit serial number stored in one-time-programmable fuses. It is read using the Read Unique ID Number instruction (4Bh) with a 4-byte address prefix, returning 8 bytes of immutable identifier. This value is used for device authentication, secure provisioning, and field traceability - and remains valid across all operating voltages and temperatures without requiring refresh or backup power.
Is the W25Q16DWZPIG TR pin-compatible with other members of the Winbond W25QxxDW family, such as the W25Q80 or W25Q32?
No, the W25Q16DWZPIG TR is not pin-compatible with W25Q80DW or W25Q32DW despite identical package and pinout - because those variants use different die sizes and internal memory organization, resulting in distinct timing parameters, status register layouts, and instruction behavior (e.g., sector count, erase times, security register mapping). Interchangeability requires full electrical and firmware validation; Winbond does not guarantee drop-in replacement across density variants.
