Product Overview
Winbond W25Q16BVSSIG: a 16 Mbit serial NOR flash memory organized as 2M x 8, reading over standard, dual or quad SPI, industrial temperature grade. It sits in the 208 mil wide 8-pin SOIC, wider than the 150 mil narrow SOIC-8, so it wants a 208 mil footprint.
Key Features
- Capacity: 16 Mbit (2M x 8), 8,192 pages of 256 bytes
- Erase granularity: 512 sectors of 4 KB, 32 blocks of 64 KB
- Interface: standard SPI, dual SPI and quad SPI
- Clock: 80 MHz across 2.7 to 3.6 V
- Supply: 2.7 to 3.6 V
- Temperature range: industrial, -40 to +85 C
- Package: 8-pin SOIC, 208 mil body
Applications
- Replacing a failed or corrupted 16 Mbit SPI boot flash on an embedded board, then writing the firmware image back with a bench programmer and SOIC clip.
- Adding firmware, font or data storage to a microcontroller project that has outgrown on-chip flash, on four SPI wires or quad I/O for faster reads.
Frequently Asked Questions
What supply voltage and clock speed does the W25Q16BVSSIG run at?
2.7 to 3.6 V, and the clock runs to 80 MHz across that whole supply range.
How small a block can it erase?
4 KB. It erases by 4 KB sector or 64 KB block and programs in 256-byte pages, so small settings records do not cost a whole block.
Is the W25Q16BV the same chip as the W25X16?
No. Both are Winbond 16 Mbit SPI flash parts, but the W25X family has no quad I/O, and the W25Q16BV reads over standard, dual and quad SPI. On the body, look for the Q: this one reads 25Q16BVSIG.
Sixteen megabits on eight pins, handed out four bits per clock once the quad lines are wired. Whatever your board should say first at power-up is now yours to write.
