Product details
Overview
W25X16VZPIG T&R 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 2.7 V to 3.6 V, 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 T&R datasheet, W25X16VZPIG T&R pinout, W25X16VZPIG T&R application, or W25X16VZPIG T&R equivalent, key selection criteria include sector-level erase granularity, hardware/software write protection via /WP and status register, SOIC-208 and WSON-6x5-mm package compatibility, and SPI Mode 0/3 interoperability with microcontroller host interfaces.
Technical Context
The W25X16VZPIG T&R implements a standard SPI-compatible bus with four signal lines (CLK, /CS, DIO, DO) and supports both single-output and dual-output read modes. Its internal architecture features an 8,192-page array (256 bytes/page), 512 erasable 4 KB sectors, and programmable block protect bits (BP2–BP0) with top/bottom selection (TB bit).
It integrates hardware write protection via active-low /WP pin and software-controlled protection through Status Register bits SRP, BP2–BP0, and TB - enabling selective memory locking without firmware intervention. The device enters high-impedance DO state during /HOLD assertion while /CS remains low, allowing SPI bus sharing with other peripherals.
Key Specifications

| SPI Interface | Standard and dual-output SPI (Fast Read Dual Output 3Bh), compatible with Modes 0 and 3 |
| Max Clock Frequency | 75 MHz - enables 150 Mbps effective throughput in dual-output mode |
| Write/Erase Endurance | 100,000 program/erase cycles per sector |

Pinout & Package
W25X16VZPIG T&R is supplied in an 8-pin WSON 6×5 mm package (Winbond package code ZP), with exposed pad for thermal dissipation and surface-mount compatibility.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| /CS | Chip Select Input | Active-low enable: drives DO to high-Z when high; required low-to-high transition before instruction acceptance after power-up |
| DO | Serial Data Output | Single-bit output pin; shifts data on falling CLK edge; becomes high-Z during /HOLD or when /CS is high |
| /WP | Write Protect Input | Active-low hardware lock: disables Status Register writes when SRP=1 and /WP=low |
| GND | Ground Reference | Primary return path for all I/O and core circuitry; must be low-impedance for noise immunity |
| DIO | Serial Data I/O | Bidirectional pin: inputs instructions/addresses on rising CLK edge; outputs data during Fast Read Dual Output (3Bh) |
| CLK | Serial Clock Input | Master-synchronized timing source; supports Modes 0 (CLK idle low) and 3 (CLK idle high) |
| /HOLD | Hold Input | Active-low pause control: suspends ongoing operations while /CS remains low; preserves internal state for resumption |
| VCC | Power Supply | 2.7–3.6 V supply; includes internal voltage monitoring for reset and write-inhibit during brown-out |
Key Features
| Feature | Design Value |
|---|---|
| Dual-output SPI read mode | Enables 150 Mbps throughput using Fast Read Dual Output (3Bh), doubling standard SPI bandwidth for rapid code shadowing |
| Hardware + software write protection | Combines /WP pin control with non-volatile status register bits (SRP, BP2–BP0, TB) to lock specific 4 KB sectors or full array |
| Flexible erase granularity | Supports page (256 B), sector (4 KB), block (64 KB), and chip-wide erase - critical for firmware update and data logging applications |
| Low-power operation | 1 µA typical standby current and automatic power-down entry reduce system-level energy consumption in battery-powered devices |
| HOLD function for multi-peripheral SPI sharing | Pauses active transfers without resetting internal state, enabling deterministic arbitration when SPI bus is shared with sensors or displays |
| JEDEC-compliant identification | Supports Manufacturer ID (90h) and JEDEC ID (9Fh) commands for automated BOM verification and field firmware validation |
Applications
| Boot Code Storage | Firmware Update Storage |
|---|---|
Use Scenario: Storing boot loader and initial firmware image executed directly from flash or copied to RAM at power-on. IC Role / Device Role / Timing Role: Non-volatile code storage with fast sequential read capability via Fast Read Dual Output (3Bh) to minimize boot latency.

| Configuration Parameter Storage | Audio/Data Logging Buffer |
Use Scenario: Persisting calibration data, network settings, and user preferences across power cycles in medical and test equipment. IC Role / Device Role / Timing Role: Small-sector (4 KB) non-volatile storage accessed infrequently but requiring high reliability and long retention. Use Value: 20-year data retention and 100,000 erase cycles ensure parameter integrity over product lifetime without wear leveling overhead. | Use Scenario: Capturing sensor telemetry or voice snippets in portable diagnostics tools and environmental monitors. IC Role / Device Role / Timing Role: Cyclic buffer implemented across multiple 4 KB sectors, erased and rewritten in round-robin fashion. Use Value: Uniform sector size simplifies firmware management of circular logs; low 1 µA power-down current extends battery life between sampling intervals. |
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-SSHN-B | 16 M-bit SPI flash; supports 85 MHz max clock but lacks dual-output mode; uses different status register layout and command set | Requires firmware adaptation for erase/write sequences and status polling; no Fast Read Dual Output acceleration | Choose when legacy Atmel toolchain support or extended temperature grade (-40°C to +105°C) is required |
| S25FL132K0XMFI010 | 16 M-bit Quad SPI flash; supports x4 I/O mode (up to 80 MHz), deeper security registers, and configurable dummy cycles | Delivers higher bandwidth than W25X16VZPIG T&R in quad mode but requires QSPI-capable host controller | Choose when migrating to QSPI interface or needing enhanced security features like secure OTP memory |
Compared with AT25DF161-SSHN-B and S25FL132K0XMFI010, the W25X16VZPIG T&R offers optimal balance of dual-output speed, simple SPI compatibility, and proven integration in cost-sensitive 3.3 V microcontroller designs - without requiring QSPI hardware or requalification for legacy command sets.

FAQ
What is the maximum SPI clock frequency supported by the W25X16VZPIG T&R?
The W25X16VZPIG T&R supports SPI clock frequencies up to 75 MHz in standard and dual-output modes. This allows 150 Mbps effective data transfer using the Fast Read Dual Output (3Bh) instruction. Timing compliance depends on meeting AC electrical specifications including tV, tVH, and tCHZ as defined in the datasheet's AC Characteristics table.
Does the W25X16VZPIG T&R support Quad SPI (QSPI) interface?
No, the W25X16VZPIG T&R does not support Quad SPI. It implements a standard 4-wire SPI interface with optional dual-output capability (using DIO and DO simultaneously during Fast Read Dual Output). QSPI functionality requires separate devices such as Winbond's W25Q series or Cypress/Infineon's S25FL family.
What package type does W25X16VZPIG T&R use, and is it lead-free?
The W25X16VZPIG T&R uses an 8-contact WSON 6×5 mm package (Winbond package code ZP) with exposed thermal pad. It is RoHS-compliant and lead-free, as confirmed by Winbond's material declarations and packaging specification documents dated March 2007 and later revisions.
How many erase cycles can the W25X16VZPIG T&R endure per sector?
The W25X16VZPIG T&R guarantees 100,000 program/erase cycles per 4 KB sector. This endurance rating applies under specified operating conditions (2.7–3.6 V, -40°C to +85°C) and assumes proper command sequencing, voltage stability, and adherence to timing parameters during erase and program operations.
Can the W25X16VZPIG T&R be used with SPI Mode 3 (CPOL=1, CPHA=1)?
Yes, the W25X16VZPIG T&R fully supports SPI Mode 3 (CPOL=1, CPHA=1) in addition to Mode 0. Data on the DIO pin is sampled on the rising edge of CLK, and data on DO and DIO is clocked out on the falling edge - consistent across both modes. No hardware or firmware modification is needed to switch between them.
