Product details
Overview
W25Q32JVXGIM TR from Winbond is a 32M-bit (4MB) serial NOR flash memory IC supporting Dual/Quad SPI, QPI, and DTR read modes. It operates from 2.7V to 3.6V, delivers up to 133MHz SPI clock rate (532MHz equivalent Quad I/O), features uniform 4KB sectors, 100K program-erase cycles per sector, and 20-year data retention. It serves as non-volatile code storage and XIP-capable execution memory in microcontroller boot systems.
For engineers reviewing the W25Q32JVXGIM TR datasheet, W25Q32JVXGIM TR pinout, W25Q32JVXGIM TR application, or W25Q32JVXGIM TR equivalent, key selection criteria include Quad Enable (QE) bit configuration, /HOLD vs /RESET pin behavior in 8-pin packages, DTR timing compliance, sector protection granularity, and VCC operating range tolerance for industrial temperature designs.
Technical Context
The W25Q32JVXGIM TR 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 active simultaneously). Its internal architecture includes a 256-byte page buffer, SFDP register for discoverable parameters, and three 256-byte security registers with OTP locks.
It supports hardware write protection via /WP and /HOLD pins (active-low), software-controlled block/sector locking (BP2–BP0, TB, SEC, CMP), and volatile/non-volatile status register bits. The /RESET pin is dedicated only in 16-pin SOIC packages; in 8-pin variants like XG, IO3 functions as /HOLD or /RESET depending on QE and HOLD/RST register settings.

Pinout & Package
W25Q32JVXGIM TR uses an 8-pad XSON 4×4×0.45 mm package (Package Code XG), compliant with JEDEC MO-252. Pin 1 is /CS; pins 2–3 are bidirectional IO1 and IO2 (/WP); pin 4 is GND; pin 5 is IO0 (DI); pin 6 is CLK; pin 7 is IO3 (/HOLD or /RESET); pin 8 is VCC.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| /CS (Pin 1) | Chip Select Input | Active-low enable: drives DO/IOx high-Z when high; required low-to-high transition after power-up before instruction acceptance |
| IO1 (Pin 2) | Data Output / Input-Output 1 | Unidirectional DO in Standard SPI; bidirectional IO1 in Dual/Quad SPI/QPI - used for read data and address transmission |
| IO2 (Pin 3) | Data Input-Output 2 | Functions as /WP in Standard/Dual SPI; becomes IO2 in Quad SPI when QE=1 - enables hardware write protection or quad data path |
| GND (Pin 4) | Ground Reference | Primary return path for VCC and all I/O signals; must be low-impedance for signal integrity and timing margin |
| IO0 (Pin 5) | Data Input / Input-Output 0 | Unidirectional DI in Standard SPI; bidirectional IO0 in Dual/Quad SPI/QPI - carries instructions, addresses, and write data |
| CLK (Pin 6) | Serial Clock Input | Edge-triggered timing source: rising edge for input sampling, falling edge for output valid - supports SPI Modes 0 and 3 |
| IO3 (Pin 7) | Hold or Reset Input | Configurable: /HOLD (active-low pause) when QE=0; /RESET (hardware reset) when QE=0 and HOLD/RST=1 - not available as functional pin when QE=1 |
| VCC (Pin 8) | Power Supply | Single 2.7–3.6 V supply; powers core logic, charge pumps, and I/O buffers - decoupling capacitor mandatory per datasheet layout guidelines |
Key Features
| Feature | Design Value |
|---|---|
| Quad Peripheral Interface (QPI) | Reduces instruction overhead by encoding commands in 4-bit nibbles - enables true XIP with minimal CPU wait states |
| DTR (Double Transfer Rate) Read | Transfers data on both clock edges during DTR Fast Read (0Dh/EDh) - doubles effective bandwidth without increasing clock frequency |
| Continuous Read Mode | Supports 8/16/32/64-byte wrap with only 8 clocks for address setup - eliminates repeated instruction overhead for sequential access |
| Security Register Set | Three 256-byte OTP-lockable registers - store cryptographic keys, calibration data, or device-specific credentials with hardware-enforced write protection |
| JEDEC SFDP Compliance | Provides standardized, discoverable parameter table - enables automatic driver configuration and vendor-agnostic firmware initialization |

FAQ
What is the package type and footprint compatibility of the W25Q32JVXGIM TR?
The W25Q32JVXGIM TR uses an 8-pad XSON 4×4×0.45 mm package (JEDEC MO-252, Package Code XG). It shares identical pad layout and dimensions with other Winbond XSON-8 variants like W25Q80DVXG and W25Q16JVXG, enabling direct PCB footprint reuse across density-scaling designs without layout changes.
Does the W25Q32JVXGIM TR support execute-in-place (XIP) operation, and what interface modes enable it?
Yes, the W25Q32JVXGIM TR supports true XIP operation via Continuous Read Mode with Quad SPI and QPI interfaces. When configured with QE=1 and using Fast Read Quad I/O (EBh) or QPI Fast Read (0Bh), it achieves sub-100 ns effective access latency - eliminating need for RAM shadowing in Cortex-M and RISC-V boot sequences.
How does the /HOLD and /RESET functionality work on the W25Q32JVXGIM TR's Pin 7 (IO3)?
On the W25Q32JVXGIM TR, Pin 7 (IO3) functions as /HOLD when QE=0 and HOLD/RST=0; as /RESET when QE=0 and HOLD/RST=1. When QE=1, IO3 becomes dedicated to Quad SPI (IO3) and neither /HOLD nor /RESET is available - requiring external reset circuitry if hardware reset is needed in Quad mode.
What security mechanisms does the W25Q32JVXGIM TR provide for protecting firmware or configuration data?
The W25Q32JVXGIM TR provides layered security: hardware write protection via /WP pin, software-configurable sector/block locking (BP2–BP0, TB, SEC), OTP-locked security registers (3×256 bytes), 64-bit unique ID, and SFDP-based parameter hiding. All protections are enforced at the silicon level and survive power cycles.
Can the W25Q32JVXGIM TR be used in automotive applications, and what qualification does it hold?
The W25Q32JVXGIM TR is rated for −40°C to +85°C operation and meets industrial reliability standards (100K cycles, 20-year retention), but it is not AEC-Q100 qualified. For automotive applications requiring formal qualification, Winbond offers the automotive-grade W25Q32JW series - the W25Q32JVXGIM TR is intended for industrial and commercial systems.
