Product details
Overview
W25Q32JWSSIQ TR from Winbond is a 1.8V, 32M-bit (4MB) serial NOR flash memory with Dual/Quad SPI interface, organized into 16,384 × 256-byte pages and supporting 4KB/32KB/64KB erase granularity. It delivers up to 133MHz Quad I/O clocking (532MB/s effective throughput), features hardware /WP and /HOLD pins, and operates across -40°C to +85°C for industrial applications including boot code storage and XIP execution.
For engineers reviewing the W25Q32JWSSIQ TR datasheet, W25Q32JWSSIQ TR pinout, W25Q32JWSSIQ TR application, or W25Q32JWSSIQ TR equivalent, this page provides verified pin functions, JEDEC-compliant ID support, SFDP register access, 64-bit unique serial number, and confirmed 8-pin SOIC-208-mil (SS) package mapping with /CS, CLK, DI/IO0, DO/IO1, /WP/IO2, /HOLD/IO3, GND, and VCC terminals.
Technical Context
The W25Q32JWSSIQ TR implements a standard SPI bus (Mode 0/3) with optional Dual/Quad I/O operation enabled via non-volatile QE bit in Status Register-2. Its command set includes Fast Read Quad I/O (EBh), Quad Input Page Program (32h), and Erase/Program Suspend (75h/7Ah), enabling deterministic interruptible operations in real-time systems.
Memory architecture supports uniform 4KB sector erase (1,024 sectors), 32KB block erase (512 blocks), and 64KB block erase (64 blocks), with programmable page writes of 1–256 bytes. Security features include three 256-byte security registers, OTP lock bits (LB1–LB3), and individual sector/block lock/unlock instructions (36h/39h/3Dh).
Key Specifications
| Parameter | Value and Actual Design Meaning |

Pinout & Package
W25Q32JWSSIQ TR is packaged in 8-pin SOIC-208-mil (Package Code SS), with exposed pad not present and lead-free RoHS-compliant construction.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 /CS | Chip Select Input | Active-low enable signal; high-impedance DO during deselect; must track VCC at power-up/down |
| 2 DO (IO1) | Data Output / Quad I/O 1 | Unidirectional output in Standard SPI; bidirectional IO1 in Dual/Quad modes; high-Z when /CS high or /HOLD low |
| 3 /WP (IO2) | Write Protect Input / Quad I/O 2 | Hardware write lock for status register; becomes IO2 when QE=1; active-low, requires external pull-up if unused |
| 4 GND | Ground Reference | Primary return path for all I/O and core logic; connects to system ground plane for noise immunity |
| 5 DI (IO0) | Data Input / Quad I/O 0 | Unidirectional input in Standard SPI; bidirectional IO0 in Dual/Quad modes; samples on CLK rising edge |
| 6 CLK | Serial Clock Input | Synchronous timing reference; supports Mode 0 (CPOL=0, CPHA=0) and Mode 3 (CPOL=1, CPHA=1) |
| 7 /HOLD (IO3) | Hold Input / Quad I/O 3 | Pauses ongoing transfers while /CS active; becomes IO3 in Quad mode; inactive when QE=1 |
| 8 VCC | Power Supply | 1.7–1.95V core supply; decoupling capacitor required within 10 mm of pin per layout guidelines |
Key Features
| Feature | Design Value |
|---|---|
| Dual/Quad SPI Interface | Enables 2×–6× faster read throughput vs standard SPI; eliminates need for parallel flash in space-constrained designs |
| Erase/Program Suspend | Allows interruption of long erase/program cycles to service time-critical interrupts, then resume without data loss |
| Three 256-byte Security Registers | Provides isolated, protected storage for keys, certificates, or calibration data inaccessible via standard read commands |
| JEDEC ID & SFDP Support | Enables automatic driver detection and configuration in Linux/RTOS environments without hard-coded parameters |
| Individual Sector/Block Lock | Permits selective write protection of specific 4KB sectors or 64KB blocks-critical for OTA update partitioning |

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 |
|---|---|---|---|
| MX25L3233FZBI-10G | 32Mb, 1.8V, 104MHz max Quad SPI clock; no /HOLD pin; 8-pin USON 4x3-mm only | Lacks hardware hold function and SOIC packaging; limited to surface-mount-only layouts | Select when board space is critical and /HOLD functionality is unnecessary |
| S25FL132K0XMFI011 | 32Mb, 1.8V, 80MHz max Quad SPI clock; includes HyperBus interface option; TFBGA24 package | Lower max frequency reduces XIP performance; HyperBus adds complexity but enables higher bandwidth in compatible controllers | Select when HyperBus controller integration exists or when TFBGA footprint aligns with existing layout |

FAQ
What is the exact package type and footprint for W25Q32JWSSIQ TR?
W25Q32JWSSIQ TR uses an 8-pin SOIC-208-mil package (Package Code SS) with 1.27 mm pitch, 5.33 mm width, and 13.97 mm length. It has no exposed pad and complies with JEDEC MS-012 standards. This footprint is pin-compatible with legacy 208-mil SOIC flash devices and supports wave or reflow soldering per IPC-J-STD-020.
Does W25Q32JWSSIQ TR support hardware reset via /RESET pin?
No, W25Q32JWSSIQ TR does not include a dedicated /RESET pin. The /RESET function is only available on SOIC-16 and TFBGA packages per Winbond documentation. For W25Q32JWSSIQ TR, system-level reset must be implemented via software sequence (66h + 99h) or power-cycle coordination.
How is Quad SPI mode enabled on W25Q32JWSSIQ TR?
Quad SPI mode on W25Q32JWSSIQ TR is enabled by setting the Quad Enable (QE) bit in Status Register-2 using Write Status Register-2 (31h) instruction. Once QE=1, pins /WP and /HOLD become IO2 and IO3 respectively, and Fast Read Quad I/O (EBh) becomes functional. The QE bit is non-volatile and persists across power cycles.
What is the minimum erase unit size supported by W25Q32JWSSIQ TR?
W25Q32JWSSIQ TR supports 4KB sector erase as its smallest erase unit, corresponding to 16 contiguous 256-byte pages. This granularity enables precise wear leveling and safe firmware patching without affecting adjacent code or configuration regions-critical for dual-bank OTA architectures.
Can W25Q32JWSSIQ TR be used in place of older W25Q32BV devices?
W25Q32JWSSIQ TR is not a direct drop-in replacement for W25Q32BV due to differences in power supply range (1.7–1.95V vs 2.7–3.6V), timing parameters, and default status register settings. While pinout matches, voltage translation and initialization sequence changes are required-designers must validate power sequencing and QE bit configuration before substitution.
