Product details
Overview
W25Q16CLZPIG TR from Winbond is a 16 M-bit (2 MB) serial NOR flash memory IC supporting Standard, Dual, and Quad SPI interfaces with up to 50 MHz clock rate, 25 MB/s continuous read throughput, and 4 KB uniform sector erase - deployed for code storage and XIP execution in microcontroller-based embedded systems.
For engineers reviewing the W25Q16CLZPIG TR datasheet, W25Q16CLZPIG TR pinout, W25Q16CLZPIG TR application, or W25Q16CLZPIG TR equivalent, key selection criteria include Quad SPI enable (QE bit), hardware write protection via /WP and /HOLD pins, 2.3–3.6 V single-supply operation, -40°C to +85°C industrial temperature range, and 64-bit unique ID for device authentication.
Technical Context
The W25Q16CLZPIG TR implements a SPI-compatible command set with Mode 0/3 support, enabling standard (DI/DO), dual (IO0/IO1), and quad (IO0–IO3) I/O configurations. Its internal architecture includes a 256-byte page buffer, 512 erasable 4 KB sectors, and 32 erasable 64 KB blocks, with dedicated logic for erase/program suspend/resume and SFDP register access.
Quad SPI operation requires non-volatile setting of the QE bit in Status Register-2, repurposing /WP and /HOLD as IO2 and IO3. The device supports JEDEC-standard manufacturer/device ID (90h/9Fh), 64-bit unique serial number (4Bh), and three 256-byte security registers with OTP lock capability.

Pinout & Package
W25Q16CLZPIG TR uses an 8-pad WSON 6×5 mm package (package code ZP), with exposed thermal pad (non-electrical). Pin functions are identical across SOIC, VSOP, and WSON variants.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| /CS | Chip Select | Active-low enable; high-impedance DO and standby current when high; must track VCC at power-up/down |
| DO (IO1) | Serial Data Output / Quad I/O 1 | Unidirectional output in Standard SPI; bidirectional I/O in Dual/Quad modes; high-impedance during /HOLD |
| /WP (IO2) | Write Protect / Quad I/O 2 | Hardware lock for Status Register writes when QE=0; becomes IO2 in Quad mode (QE=1) |
| GND | Ground Reference | Primary return path for VCC and I/O signals; connects to thermal pad in WSON |
| VCC | Power Supply | 2.3–3.6 V input; powers internal high-voltage generators for erase/program operations |
| /HOLD (IO3) | Hold Control / Quad I/O 3 | Pauses ongoing SPI transaction when low (Standard/Dual only); becomes IO3 in Quad mode (QE=1) |
| CLK | Serial Clock Input | Edge-triggered timing reference; supports Mode 0 (CLK idle low) and Mode 3 (CLK idle high) |
| DI (IO0) | Serial Data Input / Quad I/O 0 | Unidirectional input in Standard SPI; bidirectional I/O in Dual/Quad modes; ignored during /HOLD |
Key Features
| Feature | Design Value |
|---|---|
| Continuous Read Mode | As few as 8 clocks overhead to address memory; enables true XIP (execute-in-place) without external buffering |
| Quad SPI Enable (QE) | Non-volatile bit in Status Register-2; enables 4-line I/O for 200 MHz effective bandwidth and faster code shadowing |
| Hardware Write Protection | Dedicated /WP pin + SRP0/SRP1 bits allow selective locking of status register and sector/block protection settings |
| 64-bit Unique ID | Factory-programmed, read-only identifier (4Bh instruction); supports secure boot, firmware binding, and device traceability |
| Security Registers | Three 256-byte OTP-lockable registers (42h/44h/48h); used for keys, certificates, or calibration data with permanent write disable |
Applications
| Industrial HMI Firmware Storage | IoT Edge Device Boot Code |
|---|---|
|
Use Scenario: Storing GUI assets, firmware binaries, and configuration tables in panel-mounted HMIs with limited PCB space and no parallel bus interface. IC Role / Device Role / Timing Role: Primary non-volatile code storage with XIP-capable Quad SPI interface, directly executed by ARM Cortex-M7 MCU. Use Value: 4 KB sector granularity enables atomic firmware updates without erasing unrelated configuration data; 25 MB/s read speed reduces boot time by >3× vs. legacy SPI flash. |
Use Scenario: Hosting secure bootloader and signed application images in battery-powered LPWAN sensors requiring tamper-resistant storage. IC Role / Device Role / Timing Role: Trusted code repository with 64-bit unique ID and OTP-locked security registers for cryptographic key storage. Use Value: Hardware-enforced write protection prevents remote firmware corruption; JEDEC ID and SFDP register simplify auto-detection in OTA update stacks. |
| Automotive ADAS Camera Module | Medical Diagnostic Instrument Bootloader |
|
Use Scenario: Storing image processing firmware and calibration parameters in automotive-grade camera modules operating at -40°C to +85°C. IC Role / Device Role / Timing Role: Industrial-temperature serial flash providing deterministic read latency for real-time ISP initialization sequences. Use Value: 100,000+ erase cycles ensure field-upgrade longevity over 10+ years; power-down current <1 µA extends module sleep-mode battery life. |
Use Scenario: Holding FDA-compliant bootloader and self-test routines in portable ultrasound devices where data integrity is safety-critical. IC Role / Device Role / Timing Role: Certified non-volatile memory with sector-level write protection to prevent accidental overwrite of regulatory-mandated firmware. Use Value: Top/bottom array protection (TB bit) isolates bootloader region from application updates; 20-year data retention meets medical device shelf-life requirements. |
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 | Same density (16 M-bit), 3 V supply, but max clock 80 MHz; lacks 64-bit UID and SFDP register | No built-in device identification or parameter discovery; requires fixed timing setup in host driver | Prefer W25Q16CLZPIG TR when unique ID, secure boot, or dynamic SFDP-based configuration is required |
| S25FL116K10BAIR10 | 16 M-bit, 2.7–3.6 V, supports Quad SPI but requires volatile QE setting; no OTP security registers | QE resets on power cycle, increasing driver complexity; no hardware-locked key storage | Prefer W25Q16CLZPIG TR for production systems needing persistent Quad mode and cryptographic key isolation |
Compared with MX25L1606EM2I-12G and S25FL116K10BAIR10, the W25Q16CLZPIG TR delivers superior system-level security (64-bit UID + OTP security registers), guaranteed Quad SPI persistence (non-volatile QE), and standardized parameter discovery (SFDP), reducing firmware validation effort in regulated markets.

FAQ
What is the package type and footprint of the W25Q16CLZPIG TR?
The W25Q16CLZPIG TR uses an 8-pad WSON (6 mm × 5 mm) package with exposed thermal pad (non-electrical). It shares pinout compatibility with SOIC-150/208-mil and VSOP-150-mil variants, enabling drop-in replacement across form factors. The ZP package code confirms this configuration, and land pattern dimensions match JEDEC MO-241AC standards.
Does the W25Q16CLZPIG TR support Quad SPI out of the box?
No - Quad SPI operation requires explicit enabling of the non-volatile Quad Enable (QE) bit in Status Register-2 using the Write Status Register (01h) instruction. Until QE=1, /WP and /HOLD remain functional as hardware write protect and hold control pins. Once set, QE persists across power cycles, eliminating runtime reconfiguration.
How does hardware write protection work on the W25Q16CLZPIG TR?
The W25Q16CLZPIG TR combines pin-based and register-based protection: the /WP pin disables Status Register writes when low (if SRP0/SRP1 permit), while Block Protect (BP2–BP0), Top/Bottom (TB), and Sector/Block Protect (SEC) bits define protected memory regions. Protection granularity ranges from 4 KB sectors to full chip, and SRP bits lock the entire protection scheme.
What is the purpose of the 64-bit Unique ID in the W25Q16CLZPIG TR?
The factory-programmed 64-bit Unique ID (accessible via instruction 4Bh) provides cryptographically verifiable device identity for secure boot, firmware binding, anti-cloning, and field device traceability. Unlike software-generated IDs, it is immutable, unclonable, and independent of host MCU resources - a critical feature for medical and industrial certification.
Can the W25Q16CLZPIG TR be used for Execute-in-Place (XIP) applications?
Yes - the W25Q16CLZPIG TR supports true XIP via Continuous Read Mode, which minimizes instruction overhead to just 8 clocks for address setup and enables seamless streaming of executable code directly from flash to CPU. This eliminates RAM copy latency and is validated for use with ARM Cortex-M and RISC-V cores in real-time embedded systems.
