Product details
Overview
W25Q32JWZPIQ TR from Winbond is a 32M-bit (4MB) serial NOR flash memory IC designed for code storage and XIP execution in space-constrained embedded systems. It operates from 1.7V–1.95V, supports standard/Dual/Quad SPI up to 133MHz, delivers 66MB/s continuous read throughput, and features uniform 4KB sectors, 100K program-erase cycles, and 20+ year data retention.
For engineers reviewing the W25Q32JWZPIQ TR datasheet, W25Q32JWZPIQ TR pinout, W25Q32JWZPIQ TR application, or W25Q32JWZPIQ TR equivalent, this page provides verified package mapping (8-pin WSON 6×5-mm), confirmed Quad I/O timing, JEDEC ID/SFDP register support, hardware write protection via /WP, and real-world use cases in boot code storage, firmware updates, and secure parameter logging.
Technical Context
The W25Q32JWZPIQ TR implements a quad I/O SPI interface with non-volatile Quad Enable (QE) bit in Status Register-2; when QE=1, /WP and /HOLD become IO2 and IO3, enabling full 4-line bidirectional data transfer. Its architecture includes a 256-byte page buffer, sector/block erase logic, and three 256-byte security registers with OTP lock capability.
It supports SPI modes 0 and 3, features Erase/Program Suspend & Resume, and integrates hardware reset (/RESET) on compatible packages-though W25Q32JWZPIQ TR uses WSON 6×5-mm (ZP code), which lacks dedicated /RESET and instead uses /HOLD as IO3 in Quad mode per datasheet Section 3.3 and Figure 1b.

Pinout & Package
W25Q32JWZPIQ TR is packaged in an 8-pad WSON 6×5-mm (Package Code ZP), with exposed thermal pad (non-electrical). Pin 1 is /CS; pins 2–3 and 5 are bidirectional I/Os; pin 4 is GND; pin 6 is CLK; pin 7 is /HOLD (functionally IO3 in Quad mode); pin 8 is VCC.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

| 2 DO (IO1) | Data Output / I/O1 | Unidirectional output in Standard SPI; bidirectional I/O in Dual/Quad mode - used for read data and status |
| 3 /WP (IO2) | Write Protect Input / I/O2 | Hardware write lock for status register; becomes IO2 in Quad mode when QE=1 |
| 4 GND | Ground Reference | Primary return path for VCC and I/O signals; connects to PCB ground plane for noise immunity |
| 5 DI (IO0) | Data Input / I/O0 | Unidirectional input in Standard SPI; bidirectional I/O in Dual/Quad mode - carries instructions, addresses, write data |
| 6 CLK | Serial Clock Input | Edge-triggered timing reference for all SPI operations; supports modes 0 and 3 |
| 7 /HOLD (IO3) | Hold Input / I/O3 | Pauses ongoing transfers when low; becomes IO3 in Quad mode when QE=1 - no dedicated /RESET in this package |
| 8 VCC | Power Supply | 1.7–1.95 V core supply; requires local 100 nF ceramic decoupling adjacent to pin |

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 |
|---|---|---|---|
| MX25L3233FZNI-10G | 32 M-bit, 1.65–2.0 V supply, max 104 MHz Quad SPI, no integrated SFDP register | Lacks SFDP auto-configuration and 64-bit UID; requires manual timing setup in host firmware | Choose if legacy SPI controller lacks SFDP parsing capability and cost sensitivity outweighs configurability |
| S25FL132K0XMFI010 | 32 M-bit, 2.7–3.6 V supply, max 80 MHz Quad SPI, Cypress-compatible command set | Higher voltage requirement prevents direct drop-in replacement; different instruction opcodes for security registers | Choose only when migrating from Cypress-based designs and board-level voltage rails support 3.3 V operation |
Compared with MX25L3233FZNI-10G and S25FL132K0XMFI010, W25Q32JWZPIQ TR offers superior low-voltage operation, faster 133 MHz Quad I/O, built-in SFDP for plug-and-play initialization, and stronger security features including OTP-lockable sectors - making it optimal for next-generation battery-powered and secure-boot embedded systems.

FAQ
What is the package type and pin count of W25Q32JWZPIQ TR?
W25Q32JWZPIQ TR uses an 8-pad WSON 6×5-mm package (Package Code ZP) with exposed thermal pad. It has eight terminals: /CS, DO (IO1), /WP (IO2), GND, DI (IO0), CLK, /HOLD (IO3), and VCC. This matches the pinout shown in Figure 1b of the official datasheet Revision H, and confirms no dedicated /RESET pin is present in this variant.
Does W25Q32JWZPIQ TR support Quad SPI mode, and how is it enabled?
Yes, W25Q32JWZPIQ TR supports Quad SPI mode via the non-volatile Quad Enable (QE) bit in Status Register-2. When QE=1, the /WP and /HOLD pins become IO2 and IO3 respectively, enabling four-line bidirectional data transfer. This is confirmed in Sections 2, 4.2, and 3.3 of the datasheet, and requires issuing Write Status Register-2 (31h) with appropriate byte value.
What is the minimum supply voltage required for reliable operation of W25Q32JWZPIQ TR?
W25Q32JWZPIQ TR requires a minimum supply voltage of 1.7 V and operates up to 1.95 V. Below 1.7 V, the device enters reset state and rejects all commands - verified in Section 9.2 "Operating Ranges" and Figure 43 of the datasheet. This 1.7 V threshold enables compatibility with single-cell Li-ion and LiPo battery systems.
How many program-erase cycles does W25Q32JWZPIQ TR guarantee, and what is its data retention?
W25Q32JWZPIQ TR guarantees a minimum of 100,000 program-erase cycles and greater than 20 years of data retention at 25°C, as specified in Section 2 "Features" and Table 9.6 of the datasheet. These values are validated across the industrial-plus temperature range (-40°C to +105°C) per product grading.
Does W25Q32JWZPIQ TR include hardware reset capability, and which package variants support it?
No, W25Q32JWZPIQ TR does not include hardware reset capability because it uses the WSON 6×5-mm (ZP) package, which lacks the dedicated /RESET pin. Hardware /RESET is only available on SOIC-16 and TFBGA packages per Section 4.6 and Note 1 in the datasheet - W25Q32JWZPIQ TR relies solely on software reset (66h + 99h sequence).
