Product details
Overview
W25Q32JVTBIQ TR from Winbond is a 32M-bit (4MB) serial NOR flash memory IC designed for code storage and XIP (execute-in-place) in space-constrained embedded systems. It supports Standard, Dual, and Quad SPI interfaces with up to 133 MHz clock frequency, delivers 66 MB/s continuous read throughput, operates from 2.7V–3.6V, and features 4KB uniform sectors, 100K program-erase cycles, and -40°C to +105°C industrial-plus temperature range.
For engineers reviewing the W25Q32JVTBIQ TR datasheet, W25Q32JVTBIQ TR pinout, W25Q32JVTBIQ TR application, or W25Q32JVTBIQ TR equivalent, this device is selected for high-reliability firmware storage, boot code execution, and secure parameter logging where low-power operation, quad-speed interface compatibility, and extended temperature stability are required.
Technical Context
The W25Q32JVTBIQ TR implements a fully SPI-compatible command set including Standard (DI/DO), Dual (IO0/IO1), and Quad (IO0–IO3) modes, with non-volatile Quad Enable (QE) bit in Status Register-2 enabling IO2 (/WP) and IO3 (/HOLD) reassignment. Its architecture includes a 256-byte page buffer, sector/block/chip erase hierarchy, and hardware write protection via /WP and /HOLD pins.
It integrates JEDEC-compliant manufacturer/device ID, 64-bit unique serial number, SFDP register for discoverable parameters, and three 256-byte security registers. The /RESET pin is dedicated and functional only on TFBGA and SOIC-16 packages - not present in the 8-pin SOIC variant of W25Q32JVTBIQ TR.

FAQ
What is the package type and lead count of W25Q32JVTBIQ TR?
W25Q32JVTBIQ TR is packaged in an 8-pin SOIC 208-mil (package code SS) surface-mount device with gull-wing leads. This package is RoHS-compliant, halogen-free, and qualified for reflow soldering per J-STD-020. It does not include a dedicated /RESET pin - that function is only available on SOIC-16 and TFBGA variants of the W25Q32JV family.
Does W25Q32JVTBIQ TR support Quad SPI mode out of the box?
No - W25Q32JVTBIQ TR requires the Quad Enable (QE) bit in Status Register-2 to be set to '1' before Quad SPI instructions (e.g., Fast Read Quad I/O EBh) become active. By default, QE=0 after power-up or reset, so the device operates in Standard or Dual SPI mode until explicitly configured. Setting QE is non-volatile unless cleared via Write Status Register command.
What is the maximum clock frequency supported by W25Q32JVTBIQ TR in Quad SPI mode?
W25Q32JVTBIQ TR supports up to 133 MHz on the CLK pin in Quad SPI mode. When combined with four-bit-wide data transfer, this yields an effective throughput of 532 Mbps (133 MHz × 4), enabling up to 66 MB/s continuous read performance using Fast Read Quad I/O (EBh) with wrap enabled.
How many program/erase cycles does W25Q32JVTBIQ TR guarantee per sector?
W25Q32JVTBIQ TR guarantees a minimum of 100,000 program/erase cycles per 4 KB sector. This endurance rating is validated across the full industrial-plus temperature range (-40°C to +105°C) and applies to all sectors regardless of physical location within the memory array.
Is hardware reset functionality available on W25Q32JVTBIQ TR?
No - the W25Q32JVTBIQ TR (8-pin SOIC-208 package) does not include a dedicated /RESET pin. Hardware reset is only implemented on SOIC-16 and TFBGA package variants of the W25Q32JV family. For W25Q32JVTBIQ TR, system-level reset must be handled via software reset sequence (66h + 99h) or power cycle.
