Winbond Electronics Corporation W25Q32JVZPIM TR

Overview

W25Q32JVZPIM TR from Winbond is a 32M-bit (4MB) serial NOR flash memory supporting Dual/Quad SPI, QPI, and DTR read modes. It features 133 MHz clock operation, 4KB uniform sectors, 100K program-erase cycles per sector, and operates from 2.7–3.6V at -40°C to +85°C. It serves as non-volatile code storage for microcontroller boot images in space-constrained embedded systems.

For engineers reviewing the W25Q32JVZPIM TR datasheet, W25Q32JVZPIM TR pinout, W25Q32JVZPIM TR application, or W25Q32JVZPIM TR equivalent, this page delivers verified package mapping (WSON 6×5-mm, ZP code), confirmed pin functions including /CS, CLK, IO0–IO3, /WP, /HOLD, and validated support for XIP, sector-level write protection, and JEDEC SFDP compliance - all critical for firmware update architecture and BOM validation.

Technical Context

The W25Q32JVZPIM TR implements a quad-peripheral interface (QPI) with non-volatile Quad Enable (QE) bit in Status Register-2, enabling full 4-line bidirectional I/O (IO0–IO3) during instruction execution. Its continuous read mode requires only 8 clocks to address memory, supporting true execute-in-place (XIP) operation without external buffering.

It integrates three 256-byte security registers with OTP lock bits, supports DTR (Double Transfer Rate) read at up to 532 MHz effective bandwidth via Quad I/O, and provides hardware-based write protection using dedicated /WP and /HOLD pins - both repurposed as IO2 and IO3 when QE=1 - alongside volatile/non-volatile status register bits for flexible memory partitioning.

Key Specifications

Pinout & Package

W25Q32JVZPIM TR uses the WSON 6×5-mm 8-pad package (package code ZP), with exposed thermal pad. Pin 1 is /CS; pins 2–3 are bidirectional IOs; pin 4 is GND; pins 5–6 are bidirectional IOs; pin 7 is /HOLD or /RESET (function depends on QE bit); pin 8 is VCC.

FAQ

What is the package type and pin count of W25Q32JVZPIM TR?

W25Q32JVZPIM TR uses an 8-pad WSON (6 mm × 5 mm) package with exposed thermal pad (package code ZP). It has eight terminals: /CS, IO1/DO, IO2//WP, GND, IO0/DI, CLK, IO3//HOLD or /RESET, and VCC. This compact footprint supports high-density PCB layouts while maintaining thermal performance for continuous read operations.

Does W25Q32JVZPIM TR support execute-in-place (XIP) operation?

Yes, W25Q32JVZPIM TR supports true XIP via its Continuous Read Mode, which requires only 8 clocks to address memory and enables efficient instruction fetch without RAM buffering. When used with Quad SPI or QPI modes at 133 MHz, W25Q32JVZPIM TR delivers up to 66 MB/s sustained throughput - sufficient for real-time code execution on Cortex-M4/M7 microcontrollers.

How does the /WP pin function differ between standard SPI and Quad SPI modes on W25Q32JVZPIM TR?

In standard SPI mode (QE=0), the /WP pin on W25Q32JVZPIM TR is a dedicated hardware write-protect input that prevents status register modification when asserted low. In Quad SPI mode (QE=1), the same physical pin becomes IO2 - a bidirectional data line - and hardware write protection must instead be managed via status register bits (BP2–BP0, TB, SEC) and SRP/SRL configuration.

What is the role of the /HOLD or /RESET pin on W25Q32JVZPIM TR, and how is it configured?

The Pin 7 terminal on W25Q32JVZPIM TR functions as either /HOLD (to pause ongoing SPI transfers) or /RESET (to force device initialization), depending on the QE bit and status register settings. When QE=0, software can select /HOLD or /RESET behavior via the HOLD/RST bit; when QE=1, it serves exclusively as IO3. The pin is active-low in all configurations.

Is W25Q32JVZPIM TR compatible with JEDEC-standard SFDP and Unique ID features?

Yes, W25Q32JVZPIM TR fully complies with JEDEC JESD216B SFDP standard, allowing host systems to auto-discover memory geometry, timing, and erase characteristics. It also provides a factory-programmed 64-bit Unique ID accessible via instruction 4Bh - essential for device authentication, secure provisioning, and field firmware version tracking in W25Q32JVZPIM TR deployments.
