Product details
Overview
W25Q16JVSSIM TR from Winbond is a 16 M-bit (2 MB) serial NOR flash memory IC supporting Dual/Quad SPI, QPI, and DTR read modes. It features 8,192 × 256-byte pages, 4 KB uniform sector erase, and operates from 2.7 V to 3.6 V with <1 µA power-down current. It enables execute-in-place (XIP) code execution in embedded microcontrollers for boot firmware storage.
For engineers reviewing the W25Q16JVSSIM TR datasheet, W25Q16JVSSIM TR pinout, W25Q16JVSSIM TR application, or W25Q16JVSSIM TR equivalent, key selection criteria include Quad Enable (QE) bit configuration, /HOLD vs /RESET pin behavior in 8-pin SOIC, DTR timing compliance, and JEDEC SFDP register support for auto-configuration.
Technical Context
The W25Q16JVSSIM TR implements a quad-peripheral interface (QPI) mode activated via 0x38 instruction, reducing instruction overhead from 8 to 2 clock cycles by using all four I/O lines simultaneously. Its DTR read capability latches address and data on both clock edges, enabling 266 MHz (Dual) and 532 MHz (Quad) effective throughput at 133 MHz CLK.
It integrates volatile/non-volatile status registers with configurable protection: Block Protect (BP2–BP0), Top/Bottom (TB), Sector Protect (SEC), Complement (CMP), and Security Register Lock (LB1–LB3). The /WP and /HOLD pins revert to IO2/IO3 when QE=1, disabling hardware write protect and hold functions in Quad mode.

Pinout & Package
W25Q16JVSSIM TR uses an 8-pin SOIC 208-mil package (Package Code SS), with pin 1 marked by a notch or dot. All pins are electrically identical to W25Q16JV-DTR's SOIC variant and share functional mapping across SOIC/WSON/USON packages.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| /CS (Pin 1) | Chip Select Input | Active-low enable; high-impedance DO during deselect; must transition high→low after power-up before first instruction |
| DO / IO1 (Pin 2) | Data Output / Bidirectional I/O | Unidirectional output in Standard SPI; bidirectional IO1 in Dual/Quad/QPI modes; requires QE=1 for Quad use |
| /WP / IO2 (Pin 3) | Write Protect Input / Bidirectional I/O | Hardware sector lock when low in Standard/Dual mode; becomes IO2 in Quad/QPI (QE=1), disabling WP function |
| GND (Pin 4) | Ground Reference | Primary return path for VCC and I/O signals; must be low-impedance for stable DTR timing |
| DI / IO0 (Pin 5) | Data Input / Bidirectional I/O | Unidirectional input in Standard SPI; bidirectional IO0 in Dual/Quad/QPI; carries instructions, addresses, and data |
| CLK (Pin 6) | Serial Clock Input | Edge-triggered timing reference; supports Mode 0 and Mode 3; DTR uses both rising/falling edges for address/data |
| /HOLD or /RESET (Pin 7) | Hold or Reset Input / Bidirectional I/O | Pauses ongoing operation when low (/HOLD); resets device when pulsed (/RESET); becomes IO3 in Quad/QPI (QE=1) |
| VCC (Pin 8) | Power Supply | 2.7–3.6 V supply; internal regulation supports stable core voltage across temperature range |
Key Features
| Feature | Design Value |
|---|---|
| Quad Peripheral Interface (QPI) | Reduces instruction overhead from 8 to 2 clocks, accelerating XIP startup and command-intensive operations |

Equivalent & Alternatives
The following parts are listed as comparable options for similar serial NOR flash applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MX25L1606EM2I-12G | 16 M-bit, 3 V, supports standard/Dual/Quad SPI but no QPI or DTR; max CLK = 86 MHz | Lacks QPI instruction compression and DTR timing; lower max throughput (43 MB/s) | Choose when QPI/DTR are unused and cost sensitivity outweighs performance needs |
| S25FL116KAGMFI011 | 16 M-bit, 3 V, supports Quad SPI and DTR but no QPI; includes built-in ECC and sector protection lock bits | Includes hardware ECC for enhanced reliability; no QPI mode reduces instruction efficiency in XIP | Prefer for safety-critical logging where bit-error resilience > instruction latency |
Compared with MX25L1606EM2I-12G and S25FL116KAGMFI011, the W25Q16JVSSIM TR delivers highest effective bandwidth (66 MB/s) and lowest instruction overhead via QPI, making it optimal for XIP-constrained bootloaders-but requires explicit QE bit management and lacks on-die ECC.

FAQ
What is the package type and lead count of W25Q16JVSSIM TR?
W25Q16JVSSIM TR uses an 8-pin SOIC 208-mil package (Package Code SS), with standard gull-wing leads and 1.27 mm pitch. This matches the mechanical and thermal profile of industry-standard 208-mil SOIC footprints, enabling drop-in replacement in legacy PCB layouts designed for similar serial flash devices.
Does W25Q16JVSSIM TR support execute-in-place (XIP) operation?
Yes, W25Q16JVSSIM TR supports true XIP via Continuous Read Mode and Quad I/O + DTR instructions. With as few as 8 clocks to address memory and up to 66 MB/s sustained read throughput, it enables microcontrollers to fetch and execute code directly from flash without copying to RAM-reducing boot time and SRAM footprint.
How does the /HOLD pin behave when Quad Enable (QE) is set in W25Q16JVSSIM TR?
When the Quad Enable (QE) bit in Status Register-2 is set to 1, the /HOLD pin (Pin 7) of W25Q16JVSSIM TR becomes IO3 for Quad SPI and QPI operations. Its hardware hold function is disabled, and the pin serves only as a bidirectional data line-requiring software-level transaction coordination instead of hardware pausing.
What is the purpose of the SFDP register in W25Q16JVSSIM TR?
The SFDP (Serial Flash Discoverable Parameters) register in W25Q16JVSSIM TR provides standardized, read-only configuration data-including timing parameters, density, erase block sizes, and feature flags-enabling bootloaders and flash programmers to auto-configure without hard-coded device-specific tables.
Can W25Q16JVSSIM TR be used in automotive applications requiring extended temperature range?
Yes, W25Q16JVSSIM TR is rated for -40°C to +105°C operation, meeting extended temperature requirements for automotive ADAS, body control modules, and infotainment systems. Its 20-year data retention and 100K endurance further support 15+ year vehicle lifecycles with field firmware updates.
