Product details
Overview
W25Q16JVSSJQ TR from Winbond is a 16 M-bit (2 MB) Serial Flash memory IC supporting Standard, Dual, and Quad SPI interfaces with up to 133 MHz clock frequency, 4 KB uniform sector architecture, and hardware/software write protection. It operates from 2.7V–3.6V, draws <1 µA in power-down mode, and targets embedded boot code storage, XIP execution, and firmware parameter retention.
For engineers reviewing the W25Q16JVSSJQ TR datasheet, W25Q16JVSSJQ TR pinout, W25Q16JVSSJQ TR application, or W25Q16JVSSJQ TR equivalent, key selection considerations include Quad SPI enable (QE bit), /HOLD vs /RESET pin behavior in SOIC-8, 4 KB sector granularity for data logging, and JEDEC SFDP register support for auto-configuration.
Technical Context
The W25Q16JVSSJQ TR implements a quad I/O SPI interface requiring non-volatile QE bit (Status Register-2, bit 1) to be set to repurpose /WP and /HOLD as IO2 and IO3. Its block diagram includes a 256-byte page buffer, 512 × 4 KB sectors, and three status registers managing erase/program suspend, security lock bits (LB1–LB3), and volatile/non-volatile protection schemes.
It supports SPI modes 0 and 3, Fast Read Quad I/O (EBh) at up to 532 MHz effective throughput, and hardware write protection via active-low /WP pin tied to BP[2:0], TB, and CMP bits. The /HOLD pin functions only in Standard/Dual SPI; it is reassigned to IO3 in Quad mode.

FAQ
What is the package type and lead count of W25Q16JVSSJQ TR?
W25Q16JVSSJQ TR uses an 8-pin SOIC 208-mil (Package Code SS) package with gull-wing leads and 1.27 mm pitch. It is RoHS-compliant, halogen-free, and qualified per JEDEC MS-012AC mechanical standards. This package is pin-compatible with other W25Q16JV variants in SOIC-8 format but differs from WSON, USON, or WLCSP versions in thermal and layout characteristics.
Does W25Q16JVSSJQ TR support hardware reset via a dedicated /RESET pin?
No, W25Q16JVSSJQ TR does not include a dedicated hardware /RESET pin. That feature is only available on SOIC-16 and TFBGA packages per Winbond documentation. For W25Q16JVSSJQ TR, system-level reset must be implemented via software sequence: Enable Reset (66h) followed by Reset Device (99h), which takes ~30 µS to complete.
How is Quad SPI enabled on W25Q16JVSSJQ TR?
Quad SPI is enabled on W25Q16JVSSJQ TR by setting the Quad Enable (QE) bit (bit 1) in Status Register-2 using Write Status Register-2 (31h) instruction. Once QE=1, pins /WP (pin 3) and /HOLD (pin 7) become IO2 and IO3 respectively, allowing four-bit-wide data transfers using instructions like Fast Read Quad I/O (EBh).
What write protection mechanisms does W25Q16JVSSJQ TR provide?
W25Q16JVSSJQ TR provides layered write protection: hardware via active-low /WP pin, software via Status Register bits (BP2–BP0, TB, SEC, CMP), volatile/non-volatile SRP/SRL lock, and individual sector/block locks (36h/39h). The WPS bit in Status Register-3 selects between block-protect and individual-lock schemes, offering configurable security granularity.
Is W25Q16JVSSJQ TR compatible with JEDEC-standard SFDP?
Yes, W25Q16JVSSJQ TR fully supports the JEDEC JESD216 standard SFDP (Serial Flash Discoverable Parameters) register, accessible via instruction 5Ah. This 256-byte table contains vendor-independent timing, erase, and configuration data, enabling automatic driver initialization in modern bootloaders and OS flash subsystems without hard-coded assumptions.
