Product details
Overview
W25Q16JLZPIG 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 104 MHz clock rate, 4 KB uniform sector erase granularity, and 2.3–3.6 V single-supply operation. It delivers 50 MB/s continuous read throughput in Quad I/O mode and supports XIP (execute-in-place) for microcontroller code storage in space-constrained embedded systems.
For engineers reviewing the W25Q16JLZPIG TR datasheet, W25Q16JLZPIG TR pinout, W25Q16JLZPIG TR application, or W25Q16JLZPIG TR equivalent, key selection considerations include Quad Enable (QE) bit configuration, /HOLD vs /RESET pin function mapping, 4 KB sector protection granularity, and compatibility with JEDEC SFDP for auto-configuration in boot loaders.
Technical Context
The W25Q16JLZPIG TR implements a flexible SPI-compatible interface with three operational modes: Standard SPI (DI/DO), Dual SPI (IO0/IO1), and Quad SPI (IO0–IO3), where IO2 and IO3 are remapped from /WP and /HOLD pins only when the non-volatile QE bit in Status Register-2 is set. Its architecture supports simultaneous suspend/resume of program/erase operations and includes dedicated 3×256-byte security registers with OTP lock capability.
It features dual-layer write protection: hardware-level via active-low /WP pin (disabled in Quad mode), and software-level via status register bits (BP2–BP0, TB, SEC, CMP, SRP), enabling top/bottom array locking and 4 KB sector-level granularity. The device also integrates a 64-bit unique ID and JEDEC SFDP register for runtime parameter discovery.

Equivalent & Alternatives
The following parts are listed as comparable options for similar serial NOR flash applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MX25L1606EZN-12G | Same 16 M-bit density and SOIC/USON packages; supports only Standard/Dual SPI (no Quad I/O); max clock 80 MHz | Lacks Quad SPI and SFDP; not suitable for XIP or auto-configuring bootloaders requiring Quad bandwidth | Select when cost sensitivity outweighs bandwidth needs and Quad mode is unused in target design |
| S25FL116K0XMFI011 | 16 M-bit, Quad SPI, 104 MHz, but uses different status register layout and lacks 64-bit UID; supports QPI mode | Requires redesign of status register access logic; no unique ID for device binding or secure boot | Choose only if existing Cypress/Fujitsu ecosystem integration mandates QPI protocol compatibility |
Compared with MX25L1606EZN-12G and S25FL116K0XMFI011, W25Q16JLZPIG TR uniquely combines Quad I/O bandwidth, JEDEC SFDP, and factory-programmed 64-bit UID in a 2×3 mm USON package-enabling faster boot, safer firmware updates, and simplified system-level qualification.

FAQ
What is the package type and footprint of W25Q16JLZPIG TR?
W25Q16JLZPIG TR uses an 8-pad USON (Ultra Thin Small Outline No-lead) package measuring 2 mm × 3 mm with an exposed thermal pad. This compact footprint supports high-density PCB layouts in portable and space-constrained embedded designs while maintaining thermal reliability under sustained read/write loads.
Does W25Q16JLZPIG TR support Quad SPI mode out of the box?
No-W25Q16JLZPIG TR requires the non-volatile Quad Enable (QE) bit in Status Register-2 to be set to '1' before Quad SPI instructions (e.g., EBh) become functional. By default, QE=0 at power-up, so /WP and /HOLD retain their hardware protection roles until explicitly configured via Write Status Register (31h) instruction.
How does the /HOLD pin behave when QE=1 on W25Q16JLZPIG TR?
When QE=1, the /HOLD pin on W25Q16JLZPIG TR is remapped as IO3 (Quad I/O data line 3) and the /HOLD function is disabled. To retain hold functionality, QE must remain 0 and the HOLD/RST bit in Status Register-3 must be set to 0-ensuring the pin operates as /HOLD rather than /RESET.
Can W25Q16JLZPIG TR be used for secure boot applications?
Yes-W25Q16JLZPIG TR supports secure boot through its 64-bit unique serial number (for device binding), JEDEC SFDP (for verified parameter loading), and OTP-lockable security registers (for storing cryptographic keys or certificates). These features enable tamper-resistant firmware validation in certified embedded platforms.
What is the minimum erase unit size supported by W25Q16JLZPIG TR?
W25Q16JLZPIG TR supports uniform 4 KB sector erase as its smallest erasable unit-corresponding to 16 consecutive 256-byte pages. This granularity enables precise firmware module updates and parameter preservation without affecting unrelated memory regions during field upgrades.
