Product Overview
A 32-megabit (4-megabyte) serial NOR flash from Winbond's W25X family, W25X32BVSSIG runs standard and dual-output SPI at up to 104 MHz from a single 2.7 V to 3.6 V supply. The 8-pin 208-mil SOIC body holds firmware, boot code and configuration data on boards short on pins and power.
Key Features
- 32 Mbit (4,194,304 bytes), 16,384 programmable pages of 256 bytes
- Standard SPI and dual-output SPI; 104 MHz clock, 208 MHz equivalent in dual-output mode
- Single 2.7 V to 3.6 V supply
- Uniform 4 KB sector erase, 32 KB and 64 KB block erase, chip erase
- 4 mA active and 1 uA power-down current, typical
- More than 100,000 erase/write cycles; more than 20 years data retention
- Operating range -40 C to +85 C
- 8-pin 208-mil SOIC; pinout 1 /CS, 2 DO, 3 /WP, 4 GND, 5 DIO, 6 CLK, 7 /HOLD, 8 VCC
Applications
- Takes a fresh bootloader or firmware image during board-level repair of routers and consumer electronics
- Replaces a corrupted BIOS chip on a motherboard, single-board computer or industrial controller
- Stores program and asset data for custom microcontroller and FPGA builds
Frequently Asked Questions
Does it run on 5 V?
No. The supply range is 2.7 V to 3.6 V, so a 5 V rail is outside it.
Does it support quad SPI?
No. It runs standard SPI and dual-output SPI only. Winbond's quad-SPI parts are the W25Q family, a different chip.
Eight pins hold four megabytes of rewritable code in this 208-mil body. When a board goes dark over a corrupted image, this is a fresh page to write the fix on.
