Product details

Overview

W25Q16DVSSJG 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 XIP-capable continuous read mode - deployed for code storage and execution in microcontroller boot loaders, IoT firmware images, and embedded HMI graphics assets.

For engineers reviewing the W25Q16DVSSJG datasheet, W25Q16DVSSJG pinout, W25Q16DVSSJG application, or W25Q16DVSSJG equivalent, key selection considerations include Quad Enable (QE) bit configuration, /WP and /HOLD pin reassignment in Quad I/O mode, 4 KB sector erase granularity, JEDEC ID (EF4015), and SFDP register support for auto-configuration.

Technical Context

The W25Q16DVSSJG implements a SPI-compatible command set with three operational modes: Standard SPI (DI/DO), Dual SPI (IO0/IO1), and Quad SPI (IO0–IO3), where IO2 and IO3 are remapped from /WP and /HOLD only when the non-volatile Quad Enable (QE) bit in Status Register-2 is set to 1. It supports SPI modes 0 and 3, with hold and write protect functions active only in Standard/Dual modes.

Its internal architecture features an 8,192-page array (256 bytes/page), 512 erasable 4 KB sectors, and 32 erasable 64 KB blocks, enabling flexible data partitioning. Erase/program suspend/resume functionality allows background operations, while the 64-bit unique ID and three 256-byte security registers with OTP locks provide traceability and firmware integrity control.

Key Specifications

Parameter	Value and Actual Design Meaning
Memory Density	16 M-bit (2,097,152 bytes), organized as 8,192 × 256-byte pages
SPI Clock Frequency	Up to 104 MHz - enables 416 MB/s effective throughput in Quad I/O mode using Fast Read Quad I/O (EBh)
Erase Granularity	Uniform 4 KB sectors (512 total), plus 32 KB and 64 KB block erase options - supports fine-grained firmware update partitioning
Supply Voltage	2.7 V to 3.6 V single supply - compatible with 3.3 V logic systems without level shifting
Active & Power-down Current	4 mA typical active current; <1 µA typical power-down current - suitable for battery-backed or low-power wake-on-event designs
Endurance & Retention	100,000 program/erase cycles per sector; 20-year data retention at +85°C - validated for long-life industrial deployments
Operating Temperature	–40°C to +85°C - qualified for extended industrial temperature range operation

Pinout & Package

W25Q16DVSSJG is packaged in an 8-pin SOIC 208-mil (package code SS), with gull-wing leads and standard JEDEC MS-012AC footprint. Pin 1 is /CS, pin 2 is DO (IO1), pin 3 is /WP (IO2), pin 4 is GND, pin 5 is DI (IO0), pin 6 is CLK, pin 7 is /HOLD (IO3), and pin 8 is VCC.

Pin/Terminal	Circuit Role	Design Meaning
/CS (Pin 1)	Chip Select input	Active-low enable signal - must transition high→low after power-up before accepting commands; places DO in high-Z when deasserted
DO / IO1 (Pin 2)	Data Output / Bidirectional I/O	Unidirectional output in Standard SPI; becomes bidirectional IO1 in Dual/Quad modes - carries read data on falling CLK edge
/WP / IO2 (Pin 3)	Write Protect input / Bidirectional I/O	Hardware write-protection for status register when QE=0; repurposed as IO2 in Quad mode (QE=1)
GND (Pin 4)	Ground reference	Primary return path for VCC and all I/O signals - requires low-impedance PCB connection to minimize noise coupling
DI / IO0 (Pin 5)	Data Input / Bidirectional I/O	Unidirectional input in Standard SPI; becomes bidirectional IO0 in Dual/Quad modes - accepts instructions/addresses on rising CLK edge
CLK (Pin 6)	Serial clock input	Edge-triggered timing reference for all SPI transfers - supports Mode 0 (CPOL=0, CPHA=0) and Mode 3 (CPOL=1, CPHA=1)
/HOLD / IO3 (Pin 7)	Hold input / Bidirectional I/O	Pauses ongoing SPI transaction when asserted low (Standard/Dual only); repurposed as IO3 in Quad mode (QE=1)
VCC (Pin 8)	Power supply	2.7–3.6 V main supply - requires local 100 nF ceramic decoupling capacitor placed within 5 mm of pin

Key Features

Feature	Design Value
Quad SPI with QE bit control	Enables 4-line data transfer only when Status Register-2 QE=1 - prevents accidental pin remapping and ensures deterministic I/O behavior
Continuous Read Mode with wrap	Reduces instruction overhead to ≤8 clocks per 24-bit address - enables true execute-in-place (XIP) from SPI without external RAM buffering
Hardware + software write protection	Combines /WP pin control with BP0–BP2, TB, SEC, CMP, and SRP bits - allows selective locking of 4 KB sectors up to full-array protection
JEDEC-compliant identification	Supports Read JEDEC ID (9Fh), Manufacturer/Device ID (90h/92h/94h), and 64-bit Unique Serial Number (4Bh) - enables automated BOM validation and field firmware authentication
Security register bank	Three 256-byte OTP-lockable security registers - used for storing cryptographic keys, calibration data, or device-specific credentials with hardware-enforced write disable

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), 3.3 V supply, but max SPI clock 80 MHz; no Quad Enable bit - IO2/IO3 pins fixed as /WP and /HOLD	Lacks Quad SPI mode and SFDP register; supports only Standard/Dual SPI with fixed pin mapping	Select when Quad I/O is unnecessary and legacy pin compatibility with /WP and /HOLD is required
S25FL116K0XMFI011	16 M-bit, 3.0 V min supply, 108 MHz Quad SPI clock; includes built-in ECC and configurable reset polarity	Offers hardware ECC for NAND-like reliability; reset behavior differs - requires evaluation of system reset coordination	Select when bit-error resilience is critical and system design accommodates configurable reset signaling

Compared with MX25L1606EZN-12G and S25FL116K0XMFI011, W25Q16DVSSJG provides deterministic Quad SPI pin remapping via QE bit, JEDEC-standardized SFDP for automatic driver configuration, and broader industrial temperature margin - making it optimal for XIP-critical, field-upgradable embedded systems.

FAQ

What is the package type and lead count of W25Q16DVSSJG?

W25Q16DVSSJG uses an 8-pin SOIC 208-mil package (package code SS) with gull-wing leads and JEDEC MS-012AC footprint. It has no exposed pad, requires standard reflow profile for Pb-free soldering, and is compatible with automated pick-and-place equipment using IPC-7351B land patterns.

Does W25Q16DVSSJG support Quad SPI mode out of the box?

No - W25Q16DVSSJG requires the non-volatile Quad Enable (QE) bit in Status Register-2 to be set to 1 before Quad SPI instructions (e.g., EBh) function. Until configured, pins 3 (/WP) and 7 (/HOLD) retain their hardware protection roles; setting QE remaps them to IO2 and IO3 respectively.

How is the 16 M-bit capacity organized in W25Q16DVSSJG?

W25Q16DVSSJG organizes its 16 M-bit (2,097,152-byte) capacity into 8,192 uniform pages of 256 bytes each, grouped into 512 erasable 4 KB sectors and 32 erasable 64 KB blocks. This structure enables precise firmware patching and wear-leveling strategies without disturbing unrelated code sections.

Can W25Q16DVSSJG be used for execute-in-place (XIP) operation?

Yes - W25Q16DVSSJG supports true XIP via Continuous Read Mode with wrap, requiring only 8 clock cycles to initiate sequential reads after address setup. When paired with a Quad SPI host controller running Fast Read Quad I/O (EBh), it delivers sustained >52 MB/s throughput sufficient for real-time code execution.

What unique identification features does W25Q16DVSSJG provide?

W25Q16DVSSJG includes a factory-programmed 64-bit Unique Serial Number (readable via instruction 4Bh), JEDEC-standard Manufacturer ID (EFh) and Device ID (4015h), and SFDP register (5Ah) for auto-discovery of timing and feature parameters - enabling secure device binding and driverless initialization in modern embedded OSes.
