Product details
Overview
W25Q16JWZPIM TR from Winbond is a 1.8V, 16M-bit serial NOR flash memory with Dual/Quad SPI, QPI and DTR read support, organized as 8,192 × 256-byte pages. It delivers up to 133MHz Quad I/O clocking, 66MB/s continuous read throughput, and supports execute-in-place (XIP) operation for embedded code storage. It is used in microcontroller boot code storage, firmware update partitions, and parameter retention in space-constrained IoT edge nodes.
For engineers reviewing the W25Q16JWZPIM TR datasheet, W25Q16JWZPIM TR pinout, W25Q16JWZPIM TR application, or W25Q16JWZPIM TR equivalent, key selection criteria include 1.65–1.95V single-supply operation, 4KB uniform sector erase granularity, JEDEC SFDP compliance, 64-bit unique ID, and hardware write protection via /WP and /HOLD pins.
Technical Context
The W25Q16JWZPIM TR implements a quad-peripheral interface (QPI) mode activated by instruction 0x38, reducing instruction overhead to two clock cycles versus eight in standard SPI. Its status register architecture includes non-volatile Quad Enable (QE), Block Protect (BP2–BP0), Top/Bottom (TB), and Security Register Lock bits - all configurable via Write Status Register instructions.
It supports simultaneous dual-plane read operations in QPI mode and features DTR (Double Transfer Rate) read variants (e.g., 0x0D, 0xED) that latch address and data on both clock edges, doubling effective bandwidth without increasing CLK frequency. Erase/program suspend/resume functionality enables real-time interrupt handling during flash operations.

Pinout & Package
W25Q16JWZPIM TR uses an 8-pad WSON 6×5-mm package (JEDEC MO-241AC, package code ZP), with wettable flank leads for automated optical inspection. Pin 1 is marked by a dot; pin 4 is GND; pin 8 is VCC.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| /CS | Chip Select Input | Active-low enable signal - must transition high→low after power-up before first instruction |
| DO (IO1) | Serial Data Output / Bidirectional I/O1 | Outputs data in Standard SPI; becomes bidirectional IO1 in Dual/Quad SPI/QPI modes |
| /WP (IO2) | Write Protect Input / Bidirectional I/O2 | Hardware lock for status register when QE=0; repurposed as IO2 when Quad Enable bit is set |
| GND | Ground Reference | Primary return path for VCC and all I/O signals - requires low-impedance PCB plane connection |
| DI (IO0) | Serial Data Input / Bidirectional I/O0 | Accepts instructions/addresses in Standard SPI; becomes bidirectional IO0 in higher-speed modes |
| CLK | Serial Clock Input | Edge-triggered timing reference - supports SPI modes 0 and 3; DTR reads sample on both edges |
| /HOLD or /RESET (IO3) | Hold Input / Reset Input / Bidirectional I/O3 | Pauses ongoing operation when active low (QE=0); becomes IO3 in Quad/QPI modes; no dedicated /RESET in 8-pin packages |
| VCC | Power Supply | 1.65–1.95 V supply - must ramp monotonically; decoupling capacitor required within 5 mm |

Equivalent & Alternatives
The following parts are listed as comparable options for similar serial NOR flash memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MX25L1633FZUI-12G | 1.8V, 16Mb, supports DTR but lacks QPI mode; max Quad SPI clock 80MHz; no 64-bit UID | Suitable for cost-sensitive consumer devices where XIP performance is secondary to BOM cost | Select when QPI acceleration and device identity are not required; verify /HOLD pin behavior matches legacy layout |
| S25FL132K0XMFI011 | 3.0V supply only; 133MHz Quad SPI; includes on-die ECC; supports octal DTR but not QPI | Targeted at industrial controllers needing error correction for long-term log storage in EMI-heavy environments | Choose only if system uses 3.0V rails and requires ECC - incompatible with 1.8V designs without level shifters |
Compared with MX25L1633FZUI-12G and S25FL132K0XMFI011, the W25Q16JWZPIM TR uniquely combines 1.8V operation, QPI mode, DTR, and factory-unique ID in a single 6×5-mm WSON package - enabling compact, secure, high-performance boot memory where voltage, speed, and identity are jointly constrained.

FAQ
What is the package type and lead finish of W25Q16JWZPIM TR?
W25Q16JWZPIM TR uses an 8-pad WSON 6×5-mm package (JEDEC MO-241AC) with matte tin (Sn) lead finish, compliant with RoHS and REACH. The "ZP" in the part number explicitly denotes this WSON package variant, and the "IM" suffix indicates industrial temperature grade (−40°C to +85°C). The "TR" denotes tape-and-reel packaging for automated assembly.
Does W25Q16JWZPIM TR support hardware reset via a dedicated /RESET pin?
No - W25Q16JWZPIM TR does not have a dedicated /RESET pin. In its 8-pin WSON package, pin 7 functions as /HOLD when Quad Enable (QE) = 0, or as IO3 when QE = 1. Hardware reset capability is only available on Winbond's 16-pin SOIC and TFBGA packages. For W25Q16JWZPIM TR, system-level reset must be handled via software reset instructions (0x66 + 0x99) or power-cycle sequencing.
How is Quad SPI mode enabled on W25Q16JWZPIM TR?
Quad SPI mode on W25Q16JWZPIM TR is enabled by setting the non-volatile Quad Enable (QE) bit in Status Register-2 (SR2) using the Write Status Register-2 instruction (0x31). Once QE = 1, pins /WP and /HOLD become IO2 and IO3 respectively. This configuration persists across power cycles and is verified by reading SR2 (0x35). The device must be in standard SPI mode to issue the write command.
What is the purpose of the /HOLD pin on W25Q16JWZPIM TR, and when is it unavailable?
The /HOLD pin on W25Q16JWZPIM TR pauses ongoing SPI transactions (e.g., read/write) while /CS remains low, allowing shared bus arbitration. It is active-low and functional only when QE = 0. When QE = 1, pin 7 is reassigned as IO3 for Quad SPI/QPI operation, disabling /HOLD. This behavior is documented in the pin description table and confirmed in Section 3.4 of the datasheet.
Can W25Q16JWZPIM TR be used for execute-in-place (XIP) applications?
Yes - W25Q16JWZPIM TR is explicitly designed for XIP operation. Its 133MHz Quad I/O clocking, DTR read modes (e.g., 0xED), and QPI instruction efficiency reduce instruction fetch latency to enable direct CPU execution from flash. The datasheet confirms XIP suitability in General Descriptions and Functional Descriptions sections, citing performance advantages over parallel flash in real-world boot scenarios.
