Product details
Overview
W25X16VZPIG from Winbond is a 16 M-bit (2 MB) serial flash memory IC with uniform 4 KB sectors and dual-output SPI interface, operating from 2.7V to 3.6V, supporting up to 75 MHz clock and 150 Mbps data transfer via Fast Read Dual Output (3Bh), used for code storage and parameter retention in space-constrained embedded systems.
For engineers reviewing the W25X16VZPIG datasheet, W25X16VZPIG pinout, W25X16VZPIG application, or W25X16VZPIG equivalent, key selection considerations include its 8-pin WSON 6×5 mm package, hardware/software write protection via /WP and status register, sector-level erase granularity, and JEDEC-compliant identification support.
Technical Context
The W25X16VZPIG implements a standard SPI bus compatible with Modes 0 and 3, with dedicated DO and bidirectional DIO pins enabling dual-output read operations. Its internal architecture organizes memory into 8,192 programmable pages of 256 bytes each and 512 erasable 4 KB sectors.
It supports full instruction set control including Page Program (02h), Sector Erase (20h), Block Erase (D8h), Chip Erase (C7h), and Fast Read Dual Output (3Bh), with status register bits (BUSY, WEL, BP2–BP0, TB, SRP) governing write enable state, protection scope, and top/bottom array selection.

| DO | Data Output | Unidirectional output for standard SPI reads and dual-output fast reads |
| /WP | Write Protect Input | Hardware lock for status register writes when SRP = 1 and /WP = low |
| GND | Ground Reference | Common return path for all I/O and power circuits |
| DIO | Data Input/Output | Bidirectional pin for instruction/address/data input; serves as second output during Fast Read Dual Output |
| CLK | Serial Clock Input | Timing reference for all SPI transfers; sampled on rising edge for input, falling edge for output |
| /HOLD | Hold Input | Pauses ongoing SPI operation while /CS remains low; useful for multi-device bus sharing |
| VCC | Power Supply | Primary 2.7–3.6 V supply; powers core logic and I/O buffers |
Key Features
| Feature | Design Value |
|---|---|
| Dual-Output SPI Mode | Enables 150 Mbps read throughput using DO + DIO simultaneously during Fast Read (3Bh), accelerating boot code shadowing |
| Flexible Write Protection | Combines hardware (/WP pin) and software (SRP, BP2–BP0, TB bits) to protect any 4 KB sector or contiguous region, top or bottom |
| Page Programming | Writes up to 256 bytes per Page Program (02h) in <2 ms, minimizing firmware update latency |
| JEDEC ID Support | Returns manufacturer (Winbond: EFh) and device ID (3015h) via 9Fh instruction, enabling automated BOM verification |

Equivalent & Alternatives
The following parts are listed as comparable options for similar serial flash memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AT25DF161-SSH-T | 16 M-bit SPI flash; supports 85 MHz clock but lacks dual-output mode; uses different status register layout and protection scheme | Higher max clock but no Fast Read Dual Output; requires revalidation of protection initialization sequence | Choose if higher single-output speed suffices and legacy Atmel toolchain compatibility is required |
| MX25L1606EM2I-12G | 16 M-bit SPI flash; supports dual-output (3Bh) and same 75 MHz clock; identical 4 KB sector size and /WP+/HOLD pinout | Pin-to-pin compatible in SOIC-8 and PDIP-8 packages; WSON-8 (6×5 mm) footprint differs slightly (pad pitch 0.5 mm vs. Winbond's 0.65 mm) | Preferred drop-in alternative for SOIC/PDIP designs; verify WSON land pattern alignment before PCB reuse |
Compared with AT25DF161-SSH-T, W25X16VZPIG delivers faster effective read bandwidth via dual-output mode and simpler protection bit mapping; versus MX25L1606EM2I-12G, it shares functional equivalence but requires land pattern adjustment in WSON-6×5-mm layouts due to differing pad pitch.

FAQ
What is the package type and dimensions of W25X16VZPIG?
W25X16VZPIG uses an 8-pad WSON package measuring 6 mm × 5 mm (package code ZP), with exposed thermal pad and RoHS-compliant lead-free finish. It is not offered in SOIC or PDIP variants - those use different suffixes (e.g., W25X16VSIG for SOIC-208-mil). The ZP package has 0.65 mm pad pitch and requires specific stencil and reflow profile validation.
Does W25X16VZPIG support dual-output SPI reads, and how is it enabled?
Yes, W25X16VZPIG supports dual-output SPI reads using the Fast Read Dual Output instruction (0x3B). When issued, the DIO pin functions as a second data output alongside DO, doubling effective throughput. No configuration register setting is needed - execution of 0x3B automatically activates dual-output mode for that read transaction.
How does hardware write protection work on W25X16VZPIG?
Hardware write protection on W25X16VZPIG is controlled by the /WP pin in conjunction with the Status Register Protect (SRP) bit. When SRP = 1 and /WP is driven low, the Write Status Register instruction (0x01) is blocked, preventing changes to BP2–BP0 and TB bits. This ensures critical protection settings remain immutable during brown-out or noise events.
What is the minimum and maximum supply voltage for reliable operation of W25X16VZPIG?
W25X16VZPIG operates reliably from 2.7 V to 3.6 V DC. Below 2.7 V, the device enters reset and ignores instructions; above 3.6 V risks permanent damage. The /CS pin must track VCC during power-up to avoid spurious writes - a pull-up resistor on /CS is recommended to ensure clean transition above the 2.7 V threshold.
Can W25X16VZPIG be used as a direct replacement for W25X16VSIQ in an existing design?
No - W25X16VZPIG (WSON-6×5-mm) and W25X16VSIQ (SOIC-208-mil) have incompatible footprints, pinouts, and thermal characteristics. While functionally identical, the ZP and SS packages require separate PCB layouts and reflow profiles. Migration requires mechanical redesign and validation of signal integrity and thermal performance.
