• 16Mbit serial flash memory
• Data retention greater than 20 years
• Small PCB size for flexible designs 1.0" × 0.8" (2.5 cm × 2.0 cm)
• 6-pin Pmod connector with SPI interface

The PmodSF provides users with 16Mbit of non-volatile memory through the use of ST Microelectronics M25P16. By using the SPI protocol, users can both write to and read from the flash memory.

Functional Description

The PmodSF utilizes ST Microelectronics M25P16 which provides 16Mbits of flash memory that can be accessed through the SPI protocol. Although this amount of memory is very small compared to modern flash drives, the PmodSF is a great way to get introduced to controlling non-volatile memory and can be easily incorporated into projects that need a way to store some information without using the USB interface.

Interfacing with the Pmod

The PmodSF communicates with the host board via the SPI protocol. By bringing the Chip Select (CS) line low, users are able to issue a variety of read, write, and erase commands to the memory chip.

Physical Dimensions

The pins on the pin header are spaced 100 mil apart. The PCB is 1 inch long on the sides parallel to the pins on the pin header and 0.8 inches long on the sides perpendicular to the pin header.
