Product Overview
The Winbond W25X32BVSSIG is a 32-megabit (4-megabyte) serial NOR flash memory IC designed for systems with space, pin, and power constraints. Operating over a 2.7V to 3.6V supply range, this non-volatile memory utilizes standard and dual-output SPI interfaces with clock frequencies up to 104 MHz. Housed in a wide-body 8-pin SOIC (208-mil) package, it provides non-volatile storage for firmware, system parameters, boot code, and embedded applications.
Key Features
- 32M-bit (4,194,304-byte) serial NOR flash memory storage capacity
- Standard SPI and Dual-Output SPI serial interface support
- Clock operation up to 104 MHz
- Operating voltage range: 2.7 V to 3.6 V
- Array organized as 16,384 programmable pages of 256 bytes each
- 8-pin wide-body SOIC package (208-mil SS package code)
- Industrial operating temperature range: -40°C to +85°C
- RoHS-compliant, lead-free green construction
Applications
- Flashes replacement bootloader or firmware images onto damaged consumer electronics and network routers during board-level repair
- Restores corrupted BIOS chips on PC motherboards, embedded single-board computers, and industrial controllers
- Provides non-volatile program and asset data storage for custom microcontroller and FPGA prototype builds
- Services audio processors, digital instruments, and microcontroller peripherals requiring fast serial parameter reads
Frequently Asked Questions
Why does the chip marking read 25X32BVSIG instead of W25X32BVSSIG?
Winbond's SpiFlash package marking convention omits the leading 'W' on the package face and abbreviates two-letter package codes down to the second character. The package code 'SS' for the 208-mil 8-pin SOIC is represented on the IC top by a single 'S', resulting in the top marking 25X32BVSIG.
What operating voltage does this serial flash IC require?
This chip operates on a supply voltage between 2.7 V and 3.6 V. It is not rated for direct 5V logic without external level shifting.
Can I buy just the exact quantity I need for a single repair job?
Yes. Each unit is sold individually so you can order just what your bench repair requires without committing to factory reel minimums. If you are stocking your component drawers, more pieces cost less each, and the price-break table on this page shows what each quantity costs. Orders ship for an $8 flat rate, ship free once the order passes $28, and leave our Idaho warehouse the same or next business day.
