Product details
Overview
W25Q16JWSSIM TR from Winbond is a 1.8V, 16M-bit (2MB) serial flash memory IC supporting Standard, Dual, and Quad SPI interfaces with up to 133MHz Quad I/O clock rate, 4KB uniform sector architecture, and hardware/software write protection - used for code execution (XIP), firmware storage, and parameter retention in space-constrained industrial microcontroller systems.
For engineers reviewing the W25Q16JWSSIM TR datasheet, W25Q16JWSSIM TR pinout, W25Q16JWSSIM TR application, or W25Q16JWSSIM TR equivalent, key selection criteria include 1.65–1.95V supply compatibility, -40°C to +85°C industrial grade operation, Quad Enable (QE) bit configuration, /WP and /HOLD pin functionality in Dual/Quad modes, and 4KB sector erase granularity for embedded firmware updates.
Technical Context
The W25Q16JWSSIM TR implements a flexible SPI interface with three operational modes: Standard (DI/DO), Dual (IO0/IO1), and Quad (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. It supports JEDEC-standard manufacturer/device ID, SFDP register, and 64-bit unique serial number for system identification and configuration discovery.
Its memory array comprises 8192 × 256-byte pages organized into 512 erasable 4KB sectors and 32 erasable 64KB blocks, enabling fine-grained firmware partitioning. Erase/program suspend/resume capability allows background operations without halting host communication, while volatile/non-volatile status register bits (BP2–BP0, TB, SEC, CMP, SRP, WPS) provide layered, configurable write protection schemes.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 16 M-bit (2,097,152 bytes) - supports full firmware images for mid-tier MCUs without external memory expansion. |
| Supply Voltage | 1.65 V to 1.95 V - compatible with 1.8V logic domains and low-power industrial SoCs. |
| Quad SPI Clock Rate | Up to 133 MHz - enables 532 MB/s effective throughput (133 MHz × 4 lines) for fast XIP or boot code loading. |
| Operating Temperature | -40°C to +85°C - qualified for industrial-grade applications including PLCs, gateways, and motor controllers. |
| Erase Granularity | 4 KB sectors (512 total), 32 KB & 64 KB blocks - allows atomic firmware patching and parameter zone isolation. |

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 /CS | Chip Select Input | Active-low enable signal; must track VCC during power-up/down to prevent spurious commands. |
| 2 DO (IO1) | Data Output / I/O1 | Unidirectional output in Standard SPI; bidirectional I/O in Dual/Quad modes for high-speed read transfers. |
| 3 /WP (IO2) | Write Protect Input / I/O2 | Hardware write lock for status register; repurposed as IO2 in Quad mode when QE=1. |
| 4 GND | Ground Reference | Primary return path for VCC and I/O signals; requires low-impedance PCB connection for noise immunity. |
| 5 DI (IO0) | Data Input / I/O0 | Unidirectional input in Standard SPI; bidirectional I/O in Dual/Quad modes for instruction/address/data transfer. |
| 6 CLK | Serial Clock Input | Master-generated timing reference; supports SPI modes 0 and 3; max 133 MHz in Quad I/O configuration. |
| 7 /HOLD (IO3) | Hold Input / I/O3 | Pauses ongoing SPI transaction; repurposed as IO3 in Quad mode when QE=1; not available on all packages. |
| 8 VCC | Power Supply | 1.65–1.95 V core supply; decoupling capacitor (0.1 µF) required within 5 mm of pin for stable operation. |
Key Features
| Feature | Design Value |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar serial flash memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MX25L1633FZC-12G | 1.8V, 16Mb, supports DTR Quad SPI up to 80MHz; lacks SFDP register and unique ID; no /HOLD-to-IO3 remapping. | Suitable for cost-sensitive consumer designs where advanced discovery and identity features are unnecessary. | Select when legacy SPI controller compatibility is prioritized over JEDEC SFDP auto-configuration and device fingerprinting. |
| AT25SF161-SSHD-B | 1.8V, 16Mb, supports Quad SPI up to 104MHz; includes hardware reset pin; no individual block lock bits or OTP security registers. | Better suited for systems requiring dedicated hardware reset coordination across multiple peripherals. | Choose when deterministic hardware reset integration outweighs granular sector locking and cryptographic key storage needs. |
Compared with MX25L1633FZC-12G and AT25SF161-SSHD-B, the W25Q16JWSSIM TR provides superior configurability via SFDP, stronger security with OTP-locked sectors and 64-bit UID, and finer 4KB erase control - making it optimal for industrial firmware update resilience and secure provisioning workflows.

FAQ
What is the operating voltage range for the W25Q16JWSSIM TR?
The W25Q16JWSSIM TR operates from 1.65 V to 1.95 V. This narrow 1.8V nominal range ensures compatibility with modern ultra-low-power microcontrollers and reduces system-level voltage translation complexity. Operation outside this window may cause undefined behavior or permanent damage. The W25Q16JWSSIM TR includes internal voltage monitoring that places the device in reset if VCC drops below the threshold (VWI), preventing spurious writes during brown-out conditions.
Does the W25Q16JWSSIM TR support Quad SPI mode, and how is it enabled?
Yes, the W25Q16JWSSIM TR supports Quad SPI mode using instructions like Fast Read Quad I/O (EBh). Activation requires setting the Quad Enable (QE) bit in Status Register-2 via Write Status Register-2 (31h) instruction. When QE = 1, the /WP and /HOLD pins become IO2 and IO3 respectively. The W25Q16JWSSIM TR does not support volatile QE - the bit is non-volatile and retains state across power cycles unless explicitly cleared.
What package type is used for the W25Q16JWSSIM TR?
The W25Q16JWSSIM TR uses an 8-pin SOIC 208-mil package (Package Code SS), with gull-wing leads, Pb-free finish, and RoHS compliance. Its 5.3 mm × 5.3 mm body size and 0.65 mm lead pitch allow reliable hand-soldering and automated assembly. This package variant includes /HOLD functionality but does not include a dedicated hardware /RESET pin - that feature is reserved for SOIC-16 and TFBGA packages per Winbond documentation.
How many program/erase cycles does the W25Q16JWSSIM TR guarantee?
The W25Q16JWSSIM TR guarantees a minimum of 100,000 program/erase cycles per sector, validated across the full operating temperature range (-40°C to +85°C). This endurance rating applies to all 4KB sectors and is supported by on-die wear leveling management. Each cycle includes full page programming (up to 256 bytes) and sector erasure. Endurance is unaffected by use of Dual or Quad SPI modes, as the underlying NAND-like memory array operation remains unchanged.
Can the W25Q16JWSSIM TR be used for secure boot applications?
Yes, the W25Q16JWSSIM TR supports secure boot through multiple hardware-enforced mechanisms: three 256-byte OTP-lockable security registers for storing cryptographic keys, a factory-programmed 64-bit unique ID for device attestation, and configurable write protection (via BP bits, TB, SEC, and individual block locks) to prevent unauthorized firmware modification. These features are integral to the W25Q16JWSSIM TR design and require no external components to implement a trusted boot chain.
