Product Overview
A 128 Mbit serial flash memory from STMicroelectronics, part number M25P128-VMF6P. It talks over a standard SPI bus at up to 50 MHz, runs from a 2.7 to 3.6 V supply and sits in a 16-pin SO surface-mount body. The array is organized as 16M x 8: 65,536 pages of 256 bytes, grouped into 64 sectors of 2 Mbit each.
Key Features
- Density: 128 Mbit (16 Mbyte), organized 16M x 8
- Page size: 256 bytes, 65,536 pages
- Sectors: 64 sectors of 2 Mbit each
- Interface: SPI serial bus, 50 MHz maximum clock
- Supply: 2.7 to 3.6 V
- Package: 16-pin SO, surface mount
Applications
- Replacing an M25P128-VMF6P on a board that calls for this number, at the original 16-pin SO pads
- Holding a firmware or boot image of up to 16 Mbytes behind a microcontroller or FPGA SPI port
- Bench work for makers: dumping, editing and reflashing serial flash images with an SPI programmer
Frequently Asked Questions
Will it run on a 3.3 V rail?
Yes. The supply range is 2.7 to 3.6 V, and 3.3 V sits inside it.
Does it fit an 8-pin SOIC footprint?
No. This body has 16 leads, eight per side, and needs a 16-pin SO land pattern.
The M25P line started at ST, moved to Numonyx and finished at Micron, and this body still wears the ST logo from the first chapter. If the chip coming off your board reads 25P28V6P, this is its twin.
