Product details
Overview
W25Q16JVUUJM 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 for flexible code and data storage. It is used in embedded boot code storage, firmware update partitions, and XIP-capable microcontroller systems.
For engineers reviewing the W25Q16JVUUJM TR datasheet, W25Q16JVUUJM TR pinout, W25Q16JVUUJM TR application, or W25Q16JVUUJM TR equivalent, key selection criteria include quad I/O support with QE bit control, hardware /WP and /HOLD pins, 100K program-erase cycles per sector, JEDEC ID/SFDP compliance, and USON 4×3-mm package compatibility with space-constrained PCB layouts.
Technical Context
The W25Q16JVUUJM TR implements a standard SPI interface with Mode 0 and Mode 3 support, and extends functionality via configurable dual/quad I/O and QPI protocols. Its architecture includes volatile/non-volatile status registers (SR1–SR3), programmable block protection (BP2–BP0, TB, SEC, CMP), and a non-volatile Quad Enable (QE) bit that reassigns /WP and /HOLD to IO2/IO3 in Quad mode.
It supports DTR (Double Transfer Rate) read instructions across all modes-latching address and data on both clock edges-enabling higher throughput without increasing CLK frequency. The device also integrates three 256-byte security registers with OTP locks, 64-bit unique ID, and erase/program suspend/resume for real-time system responsiveness.

Equivalent & Alternatives
The following parts are listed as comparable options for similar serial NOR flash applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MX25L1606EM1I-12G | 16 M-bit, 3V, SOIC-8 package; supports standard/Dual/Quad SPI but no QPI or DTR; max CLK = 104 MHz | Lacks QPI instruction set and DTR read modes - lower bandwidth ceiling and higher instruction overhead in XIP use cases | Select when QPI/DTR are unnecessary and SOIC-8 footprint is preferred over USON 4×3-mm |
| S25FL116K0XMFI041 | 16 M-bit, 3V, USON-8 4×3-mm; supports Quad SPI and QPI but no DTR; max CLK = 104 MHz; includes sector protection via WP# only | No DTR support limits peak read throughput; lacks dedicated /HOLD pin (replaced by /RESET); no security registers or unique ID | Choose for cost-sensitive designs where DTR, security registers, and 64-bit UID are not required |
Compared with MX25L1606EM1I-12G and S25FL116K0XMFI041, the W25Q16JVUUJM TR delivers higher bandwidth via 133 MHz CLK + DTR, stronger security via OTP-locked registers and 64-bit UID, and greater flexibility via dual-function /HOLD and /WP pins - making it optimal for XIP-critical, secure, and space-constrained applications.

FAQ
What is the package type and footprint of W25Q16JVUUJM TR?
W25Q16JVUUJM TR uses an 8-pad USON (Ultra Thin Small Outline No-lead) package measuring 4 mm × 3 mm × 0.55 mm, with package code UU. It features a wettable flank design for automated optical inspection and complies with JEDEC MO-252 standards. The pinout matches other USON-8 variants in the W25Q16JV family, enabling drop-in replacement within same-package variants.
Does W25Q16JVUUJM TR support Quad Peripheral Interface (QPI) mode?
Yes, W25Q16JVUUJM TR supports QPI mode after issuing the "Enter QPI (38h)" instruction and setting the Quad Enable (QE) bit in Status Register-2. In QPI mode, all four IO lines (IO0–IO3) carry instruction, address, and data simultaneously, reducing instruction overhead from 8 to 2 clock cycles - a key enabler for low-latency execute-in-place (XIP) operation.
How does the /WP pin function differ between standard and Quad SPI modes on W25Q16JVUUJM TR?
In standard and dual SPI modes, the /WP pin provides hardware write protection for status registers. When the QE bit is set for Quad SPI operation, the /WP pin is reassigned as IO2 and loses its hardware protection function. Protection must then rely on software-configured block protect bits (BP2–BP0, TB, SEC) and SRP/SRL bits in the status registers.
What is the significance of DTR (Double Transfer Rate) support in W25Q16JVUUJM TR?
DTR support in W25Q16JVUUJM TR allows address and data to be latched on both rising and falling edges of the serial clock - doubling effective throughput without increasing CLK frequency. This is implemented in DTR Fast Read (0Dh/EDh) and DTR Burst Read (0Eh) instructions, enabling sustained 66 MB/s reads at 133 MHz while easing timing closure on high-speed PCBs.
Can W25Q16JVUUJM TR be used in automotive applications?
W25Q16JVUUJM TR is rated for −40°C to +85°C operation and meets industrial reliability standards, but it is not AEC-Q100 qualified. For automotive infotainment or body control modules requiring automotive qualification, Winbond offers the AEC-Q100 Grade 3 compliant W25Q16JWxxIM variant. W25Q16JVUUJM TR may be used in non-safety-critical automotive subsystems where qualification is not mandated.
