Product details
Overview
W25Q32JVZEJQ TR from Winbond is a 32M-bit (4MB) serial NOR flash memory IC supporting Standard, Dual, and Quad SPI interfaces with 133 MHz clock rate, 2.7–3.6 V supply, and industrial temperature range (−40°C to +85°C). It features uniform 4KB sectors, 64KB blocks, 100K program-erase cycles, and hardware write protection via /WP and /HOLD pins - used for code storage, XIP execution, and firmware updates in embedded controllers.
For engineers reviewing the W25Q32JVZEJQ TR datasheet, W25Q32JVZEJQ TR pinout, W25Q32JVZEJQ TR application, or W25Q32JVZEJQ TR equivalent, key selection considerations include Quad SPI enable (QE bit), /RESET pin availability (TFBGA/SOIC-16 only), sector-level lock granularity, SFDP register support, and 1µA typical power-down current.
Technical Context
The W25Q32JVZEJQ TR implements a SPI-compatible command set with three instruction modes: Standard (DI/DO), Dual (IO0/IO1), and Quad (IO0–IO3), where Quad mode requires non-volatile QE bit = 1 in Status Register-2. Its architecture includes a 256-byte page buffer, 1,024 erasable 4KB sectors, and dedicated security registers (3 × 256 bytes).
It supports JEDEC-standard Manufacturer ID (EFh), Device ID (4016h), 64-bit unique serial number, and SFDP v1.6 register for discoverable timing and feature parameters. Hardware reset (/RESET) is available only on TFBGA and SOIC-16 packages - not on the WSON 8-pin ZE package used by W25Q32JVZEJQ TR.

Pinout & Package
W25Q32JVZEJQ TR uses an 8-pad WSON 8×6-mm package (JEDEC MO-241AC, Package Code ZE) with wettable flanks and thermally enhanced exposed pad. Pin 1 is marked by a dot; pin 4 is GND; pin 8 is VCC. The package lacks dedicated /RESET - /HOLD (Pin 7) serves dual function but is repurposed as IO3 in Quad mode when QE=1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 /CS | Chip Select Input | Active-low enable: high = device deselected, DO in high-Z; low = active communication window |
| 2 DO (IO1) | Data Output / Bidirectional I/O | Unidirectional output in Standard SPI; bidirectional IO1 in Dual/Quad modes after QE configuration |
| 3 /WP (IO2) | Write Protect Input / Bidirectional I/O | Hardware 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 exposed thermal pad |
| 5 DI (IO0) | Data Input / Bidirectional I/O | Unidirectional input in Standard SPI; bidirectional IO0 in Dual/Quad modes |
| 6 CLK | Serial Clock Input | Synchronous timing reference for all SPI operations; supports Mode 0 and Mode 3 |
| 7 /HOLD (IO3) | Hold Input / Bidirectional I/O | Pauses ongoing read/write; becomes IO3 in Quad mode when QE=1 - no dedicated /RESET |
| 8 VCC | Power Supply | 2.7–3.6 V core and I/O supply; decoupling capacitor required near pin |

FAQ
Does W25Q32JVZEJQ TR support hardware reset (/RESET pin)?
No, W25Q32JVZEJQ TR does not support hardware reset. It uses an 8-pad WSON 8x6-mm (ZE) package, which omits the dedicated /RESET pin. Hardware reset is only available on SOIC-16 and TFBGA packages. W25Q32JVZEJQ TR relies on software reset (66h + 99h instructions) or power-cycle recovery.
What is the maximum clock frequency supported by W25Q32JVZEJQ TR in Quad SPI mode?
W25Q32JVZEJQ TR supports up to 133 MHz on the CLK pin in Quad SPI mode. With four I/O lines active, this yields an effective data transfer rate of 532 MHz (133 MHz × 4), enabling continuous read speeds up to 66 MB/s using Fast Read Quad I/O (EBh) instruction.
How is Quad SPI enabled on W25Q32JVZEJQ TR?
Quad SPI is enabled by setting the Quad Enable (QE) bit in Status Register-2 (SR2). This bit is non-volatile and must be written using Write Status Register-2 (31h) instruction. Once QE = 1, /WP (Pin 3) and /HOLD (Pin 7) become IO2 and IO3, completing the 4-line I/O interface.
Can W25Q32JVZEJQ TR be used for execute-in-place (XIP) applications?
Yes, W25Q32JVZEJQ TR supports true XIP operation via Fast Read Quad I/O (EBh) and continuous read with wrap. Its 133 MHz Quad SPI interface and low-latency page access enable direct code execution from flash on compatible microcontrollers - eliminating RAM copy overhead.
What package type does W25Q32JVZEJQ TR use, and does it include thermal pad exposure?
W25Q32JVZEJQ TR uses the 8-pad WSON 8×6-mm package (JEDEC MO-241AC, Code ZE) with an exposed thermal pad on the bottom surface. This pad must be soldered to a PCB copper pour for optimal thermal dissipation and mechanical reliability - confirmed in Winbond's Package Specification document (Rev. G, Section 10.5).
