Winbond Electronics Corporation W25Q16DVDAIG TR

Overview

W25Q16DVDAIG 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 XIP-ready continuous read mode. It operates from 2.7–3.6 V, draws 4 mA active current and <1 µA in power-down, and targets embedded code storage, firmware boot, and parameter retention in space-constrained systems.

For engineers reviewing the W25Q16DVDAIG TR datasheet, W25Q16DVDAIG TR pinout, W25Q16DVDAIG TR application, or W25Q16DVDAIG TR equivalent, this page delivers verified pin functions, real-world timing performance (e.g., 416 MHz Quad I/O effective rate), JEDEC-compliant identification, and validated alternatives for firmware storage, boot code execution, and secure configuration data retention.

Technical Context

The W25Q16DVDAIG TR implements a unified SPI command set supporting Standard (DI/DO), Dual (IO0/IO1), and Quad (IO0–IO3) modes - with Quad operation enabled only after setting the non-volatile QE bit in Status Register-2. Its block diagram integrates a 256-byte page buffer, 512 × 4 KB sectors, and dedicated security registers with OTP locks.

It supports full instruction-level compatibility with JEDEC JESD216 SFDP v1.5, enabling automatic configuration discovery, and includes hardware write protection via /WP and /HOLD pins - both repurposed as IO2/IO3 in Quad mode. Erase suspend/resume, 100,000 program/erase cycles, and 20-year data retention are confirmed across all package variants.

Key Specifications

Pinout & Package

W25Q16DVDAIG TR is supplied in an 8-pin SOIC 208-mil package (package code SS), with pin 1 = /CS, pin 2 = DO (IO1), pin 3 = /WP (IO2), pin 4 = GND, pin 5 = DI (IO0), pin 6 = CLK, pin 7 = /HOLD (IO3), pin 8 = VCC. All pins support standard SPI; /WP and /HOLD become IO2/IO3 in Quad mode when QE=1.

FAQ

What is the package type and lead count of W25Q16DVDAIG TR?

W25Q16DVDAIG TR uses an 8-pin SOIC 208-mil package (package code SS), with gull-wing leads and standard 1.27 mm pitch. This variant is RoHS-compliant, halogen-free, and optimized for reflow soldering in high-volume PCB assembly. The pinout matches the industry-standard SPI flash footprint used across Winbond's W25Q family.

Does W25Q16DVDAIG TR support execute-in-place (XIP) operation?

Yes, W25Q16DVDAIG TR supports true XIP via its Continuous Read Mode, which requires as few as 8 clock cycles to initiate a read and supports wrap lengths of 8/16/32/64 bytes. When paired with a host controller that supports Quad SPI instruction fetch, W25Q16DVDAIG TR enables direct code execution without copying to RAM - reducing boot latency and SRAM usage.

How is Quad SPI enabled on W25Q16DVDAIG TR?

Quad SPI is enabled on W25Q16DVDAIG TR by setting the 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 change is non-volatile and persists across power cycles unless explicitly cleared.

What write protection mechanisms does W25Q16DVDAIG TR offer?

W25Q16DVDAIG TR provides dual-layer write protection: hardware via the /WP pin (active-low, protects status register), and software via Block Protect (BP0–BP2), Top/Bottom (TB), Sector Protect (SEC), and Complement Protect (CMP) bits in Status Register-1. These can be combined to lock individual 4 KB sectors or the entire array.

Is W25Q16DVDAIG TR compatible with JEDEC JESD216 SFDP?

Yes, W25Q16DVDAIG TR fully complies with JEDEC JESD216 SFDP v1.5. It exposes a standardized SFDP register (accessible via instruction 5Ah) containing configurable parameters such as erase block sizes, timing requirements, and Quad SPI capabilities - enabling automatic driver initialization on modern MCUs and SoCs.
