Product details
Overview
W25Q16CVZPIG TR from Winbond is a 16 M-bit (2 MB) serial NOR flash memory IC supporting Standard, Dual, and Quad SPI interfaces with 104 MHz clock capability, 4 KB uniform sector architecture, and hardware write protection via /WP and /HOLD pins - deployed in embedded boot code storage, firmware update partitions, and XIP-capable microcontroller systems.
For engineers reviewing the W25Q16CVZPIG TR datasheet, W25Q16CVZPIG TR pinout, W25Q16CVZPIG TR application, or W25Q16CVZPIG TR equivalent, key selection criteria include Quad SPI enable (QE bit), 4 KB sector erase granularity, 2.7–3.6 V single-supply operation, and compatibility with JEDEC-standard SFDP and Unique ID read commands.
Technical Context
The W25Q16CVZPIG TR implements a SPI command-set architecture with three operational modes: Standard (DI/DO), Dual (IO0/IO1), and Quad (IO0–IO3), where Quad mode requires non-volatile QE bit setting in Status Register-2. Its internal block diagram integrates a 256-byte page buffer, sector/block erase logic, and security registers with OTP locks.
It supports continuous read mode with ≤8-clock instruction overhead for true execute-in-place (XIP) operation, and features dual-level write protection: hardware (/WP pin active-low) and software (BP2–BP0, TB, SEC, SRP0/SRP1 bits). Erase suspend/resume and power-down (1 µA typical) are supported for low-power embedded use cases.

Pinout & Package
W25Q16CVZPIG TR uses an 8-pad WSON 6×5 mm package (package code ZP), lead-free and RoHS-compliant, with exposed thermal pad for improved thermal dissipation in space-constrained PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| /CS | Chip Select Input | Active-low enable; high-impedance DO/IOx outputs when deasserted; required high-to-low transition before instruction acceptance |
| DO (IO1) | Bidirectional Data Output/Input | Serial data output in Standard/Dual SPI; IO1 in Dual/Quad SPI; driven high-Z during /HOLD or /CS high |
| /WP (IO2) | Write Protect Input / IO2 | Hardware lock for status register writes when QE=0; becomes IO2 in Quad SPI (QE=1) |
| GND | Ground Reference | Primary return path for VCC and all I/O signals; must be low-impedance connection |
| DI (IO0) | Bidirectional Data Input/Input | Serial data input in Standard/Dual SPI; IO0 in Dual/Quad SPI; sampled on CLK rising edge |
| CLK | Serial Clock Input | Master-generated timing signal; supports SPI Mode 0 (CPOL=0, CPHA=0) and Mode 3 (CPOL=1, CPHA=1) |
| /HOLD (IO3) | Hold Input / IO3 | Pauses ongoing SPI transfer while /CS is low; becomes IO3 in Quad SPI (QE=1) |
| VCC | Power Supply | 2.7–3.6 V supply; decoupling capacitor (0.1 µF) required near pin for noise immunity |

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 | Same density (16 M-bit), 104 MHz max clock, but lacks Quad SPI I/O (supports only Dual I/O); no SFDP register | Not suitable for XIP-critical designs requiring Quad I/O bandwidth or auto-configurable timing | Select only if Dual SPI suffices and SFDP-based host initialization is unnecessary |
| S25FL116K10BAIR10 | 16 M-bit, 85 MHz max clock, supports Quad SPI and SFDP, but uses different status register layout and lacks 64-bit UID | Requires firmware adaptation for status bit mapping and identity read commands | Prefer when Cypress-compatible toolchains or legacy driver support is required |
Compared with MX25L1606EZN-12G and S25FL116K10BAIR10, the W25Q16CVZPIG TR delivers higher Quad I/O bandwidth (416 MB/s), JEDEC SFDP auto-configuration, and factory-unique 64-bit ID - making it optimal for XIP-enabled, secure, and scalable embedded firmware architectures.

FAQ
What is the package type and footprint of the W25Q16CVZPIG TR?
The W25Q16CVZPIG TR uses an 8-pad WSON 6×5 mm package (code ZP) with exposed thermal pad. It is RoHS-compliant, halogen-free, and designed for reflow soldering per IPC/JEDEC J-STD-020. Footprint dimensions match standard 6×5 mm WSON land patterns with 0.5 mm pitch and 0.3 mm pad width.
Does the W25Q16CVZPIG TR support execute-in-place (XIP) operation?
Yes, the W25Q16CVZPIG TR supports true XIP via Continuous Read Mode, which requires only 8 clocks to initiate address access and sustains up to 416 MB/s throughput in Quad I/O mode. This eliminates need for RAM buffering and enables direct CPU instruction fetch from flash in compatible microcontrollers.
How is Quad SPI mode enabled on the W25Q16CVZPIG TR?
Quad SPI mode is enabled by setting the Quad Enable (QE) bit in Status Register-2 using the Write Status Register (01h) instruction. Once set, /WP and /HOLD pins become IO2 and IO3 respectively. The QE bit is non-volatile and persists across power cycles unless explicitly cleared.
What write protection mechanisms does the W25Q16CVZPIG TR provide?
The W25Q16CVZPIG TR provides layered write protection: hardware-level via /WP pin (active-low, disables status register writes), and software-level via BP2–BP0, TB, SEC, and SRP0/SRP1 bits. These allow selective locking of 4 KB sectors, top/bottom array halves, or entire memory - configurable independently of power state.
Is the W25Q16CVZPIG TR compatible with JEDEC-standard SFDP?
Yes, the W25Q16CVZPIG TR implements JEDEC JESD216-compliant SFDP (Serial Flash Discoverable Parameters) register, accessible via Read SFDP Register (5Ah) command. This allows host controllers to auto-detect timing parameters, voltage ranges, and command sets without hard-coded driver assumptions.
