Product details
Overview
W25Q16JWZPIM from Winbond is a 1.8V, 16M-bit serial flash memory IC supporting Dual/Quad SPI, QPI, and DTR read modes. It delivers up to 133MHz Quad I/O clocking, enabling 66MB/s continuous data transfer, and features uniform 4KB sector erase, 256-byte page programming, and hardware write protection via /WP and /HOLD pins - deployed in embedded boot code storage and firmware update systems.
For engineers reviewing the W25Q16JWZPIM datasheet, W25Q16JWZPIM pinout, W25Q16JWZPIM application, or W25Q16JWZPIM equivalent, key selection criteria include Quad Enable (QE) bit configuration for IO3 functionality, VCC operating range (1.65–1.95V), JEDEC ID verification (EF4015), SFDP register support, and package-specific /RESET availability.
Technical Context
The W25Q16JWZPIM implements a flexible SPI-compatible interface with mode-selectable operation: Standard SPI (DI/DO), Dual SPI (IO0/IO1), Quad SPI (IO0–IO3), and QPI (all four IOs for instruction + data). Its architecture supports both volatile and non-volatile status register bits including QE, BP2–BP0, TB, SEC, CMP, and SRP for granular memory protection.
It integrates three 256-byte security registers with OTP locks, a 64-bit unique serial number, and DTR read capability that latches address and data on both clock edges - enabling higher effective throughput without increasing CLK frequency. Erase/program suspend/resume functionality allows real-time interruption of background operations.

Pinout & Package
W25Q16JWZPIM uses an 8-pad WSON 6×5-mm package (Package Code ZP), with exposed pad for thermal dissipation and no internal die attach flag. Pin functions are identical across SOIC/WSON/USON 8-pin variants per datasheet Figure 1b and Section 2.3.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 /CS | Chip Select Input | Active-low enable; high-impedance DO/IOx when deasserted; required high-to-low transition after power-up before instruction acceptance |
| 2 DO (IO1) | Data Output / Bidirectional I/O | Unidirectional output in Standard SPI; bidirectional IO1 in Dual/Quad SPI/QPI; used for status/data reads on falling CLK edge |
| 3 /WP (IO2) | Write Protect Input / Bidirectional I/O | Hardware lock for Status Register when QE=0; becomes IO2 in Quad mode (QE=1); active-low protection signal |
| 4 GND | Ground Reference | Primary return path for VCC and all I/O signals; must be low-impedance for stable timing and noise immunity |
| 5 DI (IO0) | Data Input / Bidirectional I/O | Unidirectional input in Standard SPI; bidirectional IO0 in Dual/Quad SPI/QPI; accepts instructions/addresses on rising CLK edge |
| 6 CLK | Serial Clock Input | Synchronous timing reference for all SPI/QPI transfers; supports Mode 0 and Mode 3; DTR mode uses both edges for address/data |
| 7 /HOLD or /RESET (IO3) | Hold Input / Reset Input / Bidirectional I/O | HOLD active-low pause during active /CS; /RESET available only when QE=0 and not in Quad mode; becomes IO3 when QE=1 |
| 8 VCC | Power Supply | 1.65–1.95V supply; <0.1 µA typical standby current; requires proper decoupling near package |
Key Features

|---|---|
| Dual/Quad SPI & QPI Support | Enables scalable bandwidth: 2× (Dual), 4× (Quad), and reduced instruction overhead (QPI) - critical for XIP and fast boot |
| DTR Read Capability | Double-transfer-rate addressing and data latching doubles effective throughput without raising CLK frequency or EMI |
| Flexible Memory Protection | Combines hardware (/WP, /HOLD) and software (BP2–BP0, TB, SEC, CMP, SRP) controls for sector-, block-, or full-array locking |
| Security Registers & Unique ID | Three 256-byte OTP-lockable security registers plus 64-bit unique serial number - supports secure firmware authentication and binding |

Equivalent & Alternatives
The following parts are listed as comparable options for similar serial flash memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MX25L1633FZNI-10G | 1.8V, 16Mb, supports DTR but lacks QPI mode and SFDP register; max Quad SPI clock 80MHz | No QPI instruction reduction benefit; limited security features (no unique ID or OTP security registers) | Choose when QPI and advanced security are unnecessary and cost sensitivity outweighs bandwidth needs |
| AT25SF161-UUN-T | 1.8V, 16Mb, supports Quad SPI and DTR, but no QPI; includes hardware reset pin in all packages | /RESET available regardless of QE setting; lacks 64-bit unique ID and SFDP compliance | Prefer when deterministic hardware reset is mandatory and QPI/XIP optimization is not required |
Compared with MX25L1633FZNI-10G and AT25SF161-UUN-T, W25Q16JWZPIM provides superior bandwidth (133MHz vs ≤80MHz), QPI mode for reduced instruction overhead, JEDEC SFDP for driver portability, and integrated security primitives - making it optimal for XIP, secure OTA, and high-throughput embedded boot applications.

FAQ
What is the package type and footprint compatibility of W25Q16JWZPIM?
W25Q16JWZPIM uses an 8-pad WSON 6×5-mm package (ZP code) with standard pitch and land pattern matching JEDEC MO-241AC. It shares pinout and electrical behavior with SOIC-150/208-mil and USON-2×3-mm variants, enabling drop-in layout reuse across form factors - though thermal performance differs due to exposed pad design.
Does W25Q16JWZPIM support hardware reset, and how is it configured?
W25Q16JWZPIM does not include a dedicated /RESET pin in its WSON-8 package. Instead, pin 7 functions as /HOLD when QE=0, or as /RESET only if configured via Status Register-2 bit HOLD/RST while QE=0 - but this function is disabled when QE=1. True hardware reset requires external circuitry or software reset (66h+99h).
How is Quad SPI mode enabled on W25Q16JWZPIM, and what changes occur?
Quad SPI mode on W25Q16JWZPIM is enabled by setting the non-volatile Quad Enable (QE) bit in Status Register-2. When QE=1, pins /WP (pin 3) and /HOLD (pin 7) become IO2 and IO3 respectively, completing the four-bidirectional-I/O interface. Standard SPI instructions remain usable, but /WP and /HOLD hardware functions are disabled.
What JEDEC IDs and manufacturer ID does W25Q16JWZPIM report?
W25Q16JWZPIM reports Manufacturer ID 0xEF (Winbond) and Device ID 0x4015 for the 16M-bit density. It also supports Read JEDEC ID (9Fh), Read Manufacturer/Device ID (90h), and Read Unique ID (4Bh) - all verified in the official datasheet revision B, confirming silicon authenticity and family alignment.
Can W25Q16JWZPIM execute code directly from flash (XIP), and what modes support it?
Yes, W25Q16JWZPIM supports true execute-in-place (XIP) operation in Dual SPI, Quad SPI, and QPI modes - enabled by continuous read with wrap and low-latency instruction fetch. QPI mode reduces instruction overhead significantly (2 clocks vs 8 for standard SPI), making it optimal for deterministic XIP in real-time embedded systems.
