Product details
Overview
W25Q16BVZPIG from Winbond is a 16 M-bit (2 MB) serial NOR flash memory IC supporting Standard, Dual, and Quad SPI interfaces with up to 104 MHz clock frequency, 4 KB uniform sector erase granularity, and true execute-in-place (XIP) capability via Continuous Read Mode. It operates from a single 2.7–3.6 V supply, draws 4 mA active current and <1 µA in power-down mode, and targets embedded code storage and data logging in space-constrained industrial controllers.
For engineers reviewing the W25Q16BVZPIG datasheet, W25Q16BVZPIG pinout, W25Q16BVZPIG application, or W25Q16BVZPIG equivalent, key selection criteria include Quad SPI timing compliance (QE bit enablement), /WP and /HOLD pin behavior under Quad I/O mode, 4 KB sector flexibility for firmware partitioning, and JEDEC ID (EF4015) validation for secure boot chain integration.
Technical Context
The W25Q16BVZPIG implements a SPI command set compliant with Modes 0 and 3, with dedicated hardware logic for sector/block erase control, status register latching (WEL, BP bits, QE), and quad I/O reconfiguration where /WP and /HOLD become IO2/IO3 only after setting the non-volatile Quad Enable (QE) bit in Status Register-2.
Its architecture features an 8,192 × 256-byte page array, 512 erasable 4 KB sectors, and 32 erasable 64 KB blocks, enabling fine-grained firmware updates and parameter storage. The device supports Fast Read Quad I/O (EBh) at up to 416 MHz equivalent bandwidth and includes hardware write protection via /WP pin (active low) and software lock-down via SRP bits - both validated for -40°C to +85°C operation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 16 M-bit (2,097,152 bytes), organized as 8,192 pages × 256 bytes - enables full MCU firmware image storage with room for OTA update staging. |
| Sector Size | Uniform 4 KB sectors (512 total) - allows independent erasure of bootloader, app, and config partitions without disturbing adjacent regions. |
| Max SPI Clock | 104 MHz standard SPI; 208 MHz dual output; 416 MHz quad output - delivers 50 MB/s continuous read throughput for XIP execution. |
| Supply Voltage | 2.7 V to 3.6 V single supply - compatible with 3.3 V logic domains and eliminates need for level shifters in most microcontroller interfaces. |
| Write/Erase Endurance | ≥100,000 program/erase cycles per sector - supports frequent field firmware updates over product lifetime. |
| Data Retention | ≥20 years at +85°C - ensures long-term reliability for industrial and automotive telematics applications. |
| JEDEC ID | EF4015 (Manufacturer ID EFh, Memory Type 40h, Capacity 15h) - enables automatic device identification in bootloader initialization sequences. |
Pinout & Package
W25Q16BVZPIG uses the 8-contact 6×5 mm WSON package (package code ZP), with exposed pad for thermal dissipation and no internal heatsink requirement in typical 2-layer PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 /CS | Chip Select Input | Active-low enable signal; must transition high→low before instruction acceptance; high-impedance DO during deselect. |
| 2 DO (IO1) | Data Output / Bidirectional I/O1 | Unidirectional output in Standard SPI; bidirectional in Dual/Quad SPI; used for read data and status feedback. |
| 3 /WP (IO2) | Hardware Write Protect / Bidirectional I/O2 | Active-low hardware lock for Status Register; repurposed as IO2 in Quad SPI when QE=1. |
| 4 GND | Ground Reference | Primary return path for VCC and I/O signals; requires low-impedance connection to PCB ground plane. |
| 5 DI (IO0) | Data Input / Bidirectional I/O0 | Unidirectional input in Standard SPI; bidirectional in Dual/Quad SPI; carries instructions, addresses, and write data. |
| 6 CLK | Serial Clock Input | Edge-triggered timing reference; supports Modes 0 and 3; max 104 MHz frequency defines interface bandwidth ceiling. |
| 7 /HOLD (IO3) | Hold Input / Bidirectional I/O3 | Pauses ongoing SPI transaction while /CS remains low; repurposed as IO3 in Quad SPI when QE=1. |
| 8 VCC | Power Supply | 2.7–3.6 V main supply; internal voltage regulation enables stable core operation across rail variation. |
Key Features
| Feature | Design Value |
|---|---|
| Continuous Read Mode | Enables true XIP with ≤8-clock instruction overhead per 24-bit address access - eliminates external RAM buffering for real-time code execution. |
| Quad SPI Reconfiguration | IO0–IO3 pins activated via non-volatile QE bit in Status Register-2 - allows runtime switching between Standard/Dual/Quad modes without hardware change. |
| Flexible Erase Architecture | Supports 4 KB sector, 32 KB block, 64 KB block, and full chip erase - permits incremental firmware patching and secure key revocation. |
| 64-Bit Unique ID | Factory-programmed serial number per die - enables device-level traceability, secure provisioning, and anti-counterfeiting in production firmware signing. |
| Hardware + Software Write Protection | Combines /WP pin control with SRP/BP bits in Status Register - provides layered defense against accidental or malicious writes during power transients. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar serial NOR flash memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MX25L1606EZUI-12G | Same density (16 M-bit), SOIC-8 package, but max SPI clock 80 MHz; lacks Quad I/O support and Continuous Read Mode. | Lower bandwidth limits XIP performance; no QE bit or IO2/IO3 reconfiguration - unsuitable for high-speed boot scenarios. | Select only if cost sensitivity outweighs speed and feature requirements; verify /WP and /HOLD remain functional in all SPI modes. |
| S25FL116K10BAIR10 | 16 M-bit, 104 MHz clock, supports Quad SPI and XIP, but uses different status register layout and JEDEC ID (012016); requires updated driver initialization. | Compatible timing and sector structure, but firmware must be adapted for Cypress-specific security register mapping and reset behavior. | Choose when migrating from Cypress ecosystem; validate SRP/BP bit positions and power-up timing against Winbond's tPUW specification. |
Compared with MX25L1606EZUI-12G, W25Q16BVZPIG delivers 30% higher SPI bandwidth and Quad I/O flexibility; versus S25FL116K10BAIR10, it offers identical performance but requires no driver porting for Winbond-standard status register access and JEDEC ID handling.

FAQ
What is the package type and footprint of W25Q16BVZPIG?
W25Q16BVZPIG uses the 8-contact 6×5 mm WSON package (ZP code) with an exposed thermal pad. Its footprint matches JEDEC MO-241AC standards and requires no solder mask defined pad opening. The package supports reflow per J-STD-020, and its compact size reduces PCB area by ~60% versus SOIC-8 alternatives while maintaining thermal performance up to 70°C ambient.
Does W25Q16BVZPIG support execute-in-place (XIP) operation?
Yes, W25Q16BVZPIG supports true XIP via its Continuous Read Mode, which reduces instruction overhead to as few as 8 clock cycles for 24-bit address access. This enables direct CPU instruction fetch over Quad SPI at up to 416 MHz equivalent bandwidth, eliminating the need for external RAM buffering in real-time firmware execution - a capability confirmed in Section 1.1 and Figure 2 of the official datasheet.
How is Quad SPI mode enabled on W25Q16BVZPIG?
Quad SPI mode on W25Q16BVZPIG is enabled by setting the non-volatile Quad Enable (QE) bit in Status Register-2 using the Write Status Register (01h) instruction. Once QE=1, the /WP and /HOLD pins become IO2 and IO3 respectively. This configuration persists across power cycles and is required before issuing Quad I/O instructions like Fast Read Quad I/O (EBh).
What write protection mechanisms does W25Q16BVZPIG provide?
W25Q16BVZPIG provides layered write protection: hardware-level via the active-low /WP pin (disabled in Quad SPI), software-level via Block Protect (BP2–BP0) and Status Register Protect (SRP0/SRP1) bits, and system-level via Power-down instruction lockout. All mechanisms are validated across the -40°C to +85°C range and interact to prevent unintended writes during power transients or firmware errors.
Is W25Q16BVZPIG pin-compatible with other W25Q16xV variants?
W25Q16BVZPIG shares identical pinout and electrical characteristics with other W25Q16BV variants in the same package type (e.g., W25Q16BVSFIG in SOIC-208). However, it is not pin-compatible with W25Q16JW or W25Q16DW families due to differences in status register mapping, QE bit location, and power-up timing - always verify top-marking and datasheet revision before substitution.
