Product details
Overview
W25Q16BVSFIG TR from Winbond is a 16 M-bit (2 MB) serial NOR flash memory IC supporting Standard, Dual, and Quad SPI interfaces with 4 KB uniform sectors, 104 MHz max clock frequency, and true execute-in-place (XIP) capability via Continuous Read Mode - used for code storage and firmware boot in microcontroller-based embedded systems.
For engineers reviewing the W25Q16BVSFIG TR datasheet, W25Q16BVSFIG TR pinout, W25Q16BVSFIG TR application, or W25Q16BVSFIG TR equivalent, key selection factors include Quad SPI bandwidth (416 MHz equivalent), hardware write protection (/WP & /HOLD pins), JEDEC ID and 64-bit unique serial number support, and compatibility with -40°C to +85°C industrial temperature operation.
Technical Context
The W25Q16BVSFIG TR implements a SPI command set compliant with Modes 0 and 3, with configurable I/O mapping: DI/DO for Standard/Dual SPI, and IO0–IO3 (reassigning /WP and /HOLD) for Quad SPI when the non-volatile Quad Enable (QE) bit in Status Register-2 is set. It supports 256-byte page programming and sector/block erase granularity (4 KB / 32 KB / 64 KB).
Its internal architecture includes a 256-byte page buffer, status register with BUSY/WEL/BP/SRP/QE bits, and high-voltage generators for erase/program operations. Power management features include <1 µA power-down current and automatic write-disable after power-up (tPUW delay) and post-operation.

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 /CS | Chip Select Input | Active-low enable; places DO in high-impedance state when high; must transition high→low before new instruction accepted |

| 3 /WP (IO2) | Write Protect Input / I/O2 | Hardware write lock for status register when low; repurposed as IO2 in Quad SPI (QE=1) |
| 4 GND | Ground Reference | Primary return path for VCC and all I/O signals; requires low-impedance PCB connection |
| 5 DI (IO0) | Data Input / I/O0 | Unidirectional input in Standard SPI; bidirectional I/O in Dual/Quad SPI; accepts instructions/addresses/data on CLK rising edge |
| 6 CLK | Serial Clock Input | Master-generated timing signal; supports SPI Modes 0 and 3; max 104 MHz frequency |
| 7 /HOLD (IO3) | Hold Input / I/O3 | Pauses active SPI transaction when low (requires /CS low); repurposed as IO3 in Quad SPI (QE=1) |
| 8 VCC | Power Supply | 2.7–3.6 V supply; decoupling capacitor (0.1 µF) required near pin for noise immunity |

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 |
|---|---|---|---|
| Winbond W25Q16JVSNIQ | Newer generation with enhanced reliability (AEC-Q100 Grade 3), higher endurance (1M cycles), and extended temp range (-40°C to +105°C) | Better suited for automotive infotainment and ADAS where extended temperature and lifetime are critical | Select W25Q16JVSNIQ if AEC-Q100 compliance or >100k cycle requirement is mandatory; not pin-compatible due to different package marking and internal ECC behavior |
| Micron MT25QL128ABA1EW9-0SIT | 128 M-bit density, octal DTR support, built-in ECC, and 133 MHz clock; requires different initialization sequence and status register layout | Targets high-end applications needing larger code space and error correction, e.g., Linux-capable SoMs | Choose MT25QL128ABA1EW9-0SIT only when scaling beyond 16 M-bit or requiring hardware ECC; not drop-in - firmware driver changes required |
Compared with W25Q16JVSNIQ and MT25QL128ABA1EW9-0SIT, the W25Q16BVSFIG TR offers optimal cost-performance balance for industrial MCU boot storage, with proven interoperability across legacy toolchains and no ECC or octal-mode dependencies - making it ideal for stable, long-lifecycle designs.

FAQ
What is the maximum clock frequency supported by the W25Q16BVSFIG TR in Quad SPI mode?
The W25Q16BVSFIG TR supports up to 104 MHz on the CLK pin in Quad SPI mode. When using Fast Read Quad I/O (EBh) or Fast Read Quad Output (6Bh) instructions, this yields an effective data transfer rate of 416 MHz (104 MHz × 4 data lines), enabling 50 MB/s continuous read throughput - sufficient for real-time code execution without buffering.
Does the W25Q16BVSFIG TR support execute-in-place (XIP) operation?
Yes, the W25Q16BVSFIG TR supports true XIP via its Continuous Read Mode, which reduces instruction overhead to just 8 clocks for addressing - allowing microcontrollers to fetch and execute code directly from flash without copying to RAM. This is enabled by Fast Read Quad I/O (EBh) and requires the Quad Enable (QE) bit in Status Register-2 to be set.
How is hardware write protection implemented on the W25Q16BVSFIG TR?
The W25Q16BVSFIG TR implements hardware write protection using the /WP (pin 3) signal, which - when held low - prevents writes to the status register. This works in conjunction with software-configurable Block Protect (BP) and Status Register Protect (SRP) bits. Note that /WP is disabled during Quad SPI operation (when QE=1), as pin 3 becomes IO2.
What package type does the W25Q16BVSFIG TR use, and what are its key mechanical features?
The W25Q16BVSFIG TR uses an 8-pin SOIC 208-mil package (package code SS), with 1.27 mm lead pitch, gull-wing leads, and standard JEDEC MS-012AC footprint. Its 5.33 mm × 5.33 mm body size and 2.67 mm height make it compatible with automated SMT assembly and reflow profiles for lead-free processes.
Can the W25Q16BVSFIG TR be used in automotive applications?
The W25Q16BVSFIG TR is rated for -40°C to +85°C operation and meets industrial reliability standards, but it is not AEC-Q100 qualified. For automotive body electronics or infotainment, Winbond's newer W25Q16JVSNIQ (AEC-Q100 Grade 3) is recommended. The W25Q16BVSFIG TR remains suitable for non-safety-critical automotive accessories where extended qualification is not mandated.
