Product details
Overview
W25Q16JVSSJM 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 operates from 2.7V to 3.6V, delivers up to 133 MHz SPI clock rate (532 MHz equivalent in Quad I/O), and features uniform 4 KB sectors, 100K program-erase cycles, and >20-year data retention. It serves as non-volatile code storage and XIP (execute-in-place) memory in microcontroller boot systems.
For engineers reviewing the W25Q16JVSSJM TR datasheet, W25Q16JVSSJM TR pinout, W25Q16JVSSJM TR application, or W25Q16JVSSJM TR equivalent, key selection criteria include quad I/O throughput, hardware write protection via /WP and /HOLD pins, JEDEC-compliant SFDP register support, and SOIC-8 (208-mil) package compatibility with industrial temperature range (–40°C to +85°C).
Technical Context
The W25Q16JVSSJM TR implements a flexible SPI-compatible interface with mode-selectable operation: Standard SPI (4-wire), Dual SPI (IO0/IO1), Quad SPI (IO0–IO3), and QPI (all four IOs for instruction + data). Its architecture supports true XIP via Continuous Read Mode with ≤8-clock address overhead and wrap lengths of 8/16/32/64 bytes.
Functional control is managed through volatile and non-volatile status registers - including Quad Enable (QE), Block Protect (BP2–BP0), Top/Bottom protect (TB), and Security Register Lock (LB1–LB3). The /RESET pin is functional only in 8-pin packages when QE = 0; otherwise, /HOLD and /WP are repurposed as IO2/IO3 in Quad mode.

Pinout & Package
W25Q16JVSSJM TR is supplied in an 8-pin SOIC-208-mil package (package code SS), with industry-standard pinout and footprint. Pin functions are identical across SOIC, WSON, and USON variants per Winbond's unified pin description table.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 /CS | Chip Select Input | Active-low enable; high-impedance DO during deselect; must transition high→low after power-up to accept instructions |
| 2 DO (IO1) | Data Output / Bidirectional I/O | Unidirectional output in Standard SPI; bidirectional IO1 in Dual/Quad SPI and QPI modes |
| 3 /WP (IO2) | Write Protect Input / Bidirectional I/O | Hardware sector lock when low (if SRP=0); becomes IO2 in Quad/QPI mode when 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 / Bidirectional I/O | Unidirectional input in Standard SPI; bidirectional IO0 in Dual/Quad SPI and QPI modes |
| 6 CLK | Serial Clock Input | Edge-triggered timing reference; supports SPI modes 0 and 3; DTR reads sample on both edges |
| 7 /HOLD or /RESET (IO3) | Hold or Reset Input / Bidirectional I/O | Pauses ongoing read/write when low (Standard/Dual SPI); dedicated /RESET only if QE=0 and not in Quad mode |
| 8 VCC | Power Supply | Single 2.7–3.6 V supply; <1 µA typical standby current enables ultra-low-power system sleep states |
Key Features
| Feature | Design Value |
|---|---|
| Quad Peripheral Interface (QPI) | Reduces instruction overhead from 8 clocks to 2 clocks per command - critical for deterministic XIP latency |
| Double Transfer Rate (DTR) Read | Enables full-duplex address/data transfer on rising/falling CLK edges - doubles effective bandwidth without raising frequency |
| Erase/Program Suspend & Resume | Allows background erase or program to be paused for urgent reads - essential for real-time firmware update scenarios |
| JEDEC SFDP v1.6 Register | Provides standardized, controller-readable parameter table - eliminates hard-coded timing constants in bootloader |
| OTP-Lockable Security Registers | Three 256-byte regions with one-time-programmable locks - suitable for storing cryptographic keys or calibration data |

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 |
|---|---|---|---|
| MX25L1606E/MX25L1633F | Lacks QPI and DTR support; max SPI clock 80 MHz; no SFDP register; 64-bit UID not guaranteed | Suitable for cost-sensitive, non-XIP designs where boot speed and auto-configuration are not required | Choose when legacy SPI-only interface suffices and QPI/DTR/XIP are unnecessary |
| S25FL116K | Supports QPI but no DTR; 1.8 V/3.0 V dual supply; lower endurance (50K cycles); no OTP security registers | Better for low-voltage embedded systems; lacks hardware-based security for sensitive data storage | Prefer when operating at 1.8 V is mandatory and security register locking is not needed |
Compared with MX25L1606E and S25FL116K, the W25Q16JVSSJM TR uniquely combines QPI, DTR, SFDP, OTP security registers, and 100K-cycle endurance in a single 3.3 V SOIC-208 package - making it optimal for XIP-capable, secure, high-throughput embedded boot applications.

FAQ
What is the package type and lead count of the W25Q16JVSSJM TR?
The W25Q16JVSSJM TR uses an 8-pin SOIC-208-mil (0.208 inch wide) surface-mount package with standard gull-wing leads. This package matches industry-standard footprints for easy drop-in replacement and is specified in Winbond's datasheet as package code "SS". It is RoHS-compliant and rated for industrial temperature range (–40°C to +85°C).
Does the W25Q16JVSSJM TR support execute-in-place (XIP) operation?
Yes, the W25Q16JVSSJM TR supports true XIP via its Continuous Read Mode and Quad Peripheral Interface (QPI). With as few as 8 clocks to address memory and wrap lengths up to 64 bytes, it enables low-latency instruction fetch directly from flash - eliminating need for RAM shadowing in many MCU boot and firmware execution scenarios.
How does the /WP and /HOLD pin behavior change in Quad SPI mode?
In Quad SPI mode (enabled by setting the Quad Enable bit in Status Register-2), the /WP and /HOLD pins of the W25Q16JVSSJM TR become IO2 and IO3 respectively. Their hardware protection functions are disabled; software-based block protection via status register bits (BP2–BP0, TB, SEC) remains fully operational and is recommended for secure write control.
What is the purpose of the SFDP register in the W25Q16JVSSJM TR?
The W25Q16JVSSJM TR includes a JEDEC JESD216-compliant SFDP (Serial Flash Discoverable Parameters) v1.6 register that provides a standardized, controller-readable table of timing parameters, erase block sizes, and feature flags. This eliminates hardcoded assumptions in bootloaders and enables automatic, future-proof configuration across different flash vendors and densities.
Can the W25Q16JVSSJM TR be used in automotive applications?
The W25Q16JVSSJM TR is qualified for industrial temperature range (–40°C to +85°C) and meets reliability requirements for many automotive infotainment and ADAS subsystems. While not AEC-Q100 certified out-of-box, its 20-year data retention, 100K endurance, and robust write protection make it widely deployed in automotive camera modules and gateway ECUs where extended qualification is performed at system level.
