Chips that support SPI can have data transfer rates 14 up to several tens of Mbit/sec. Chips are addressed with a 15 controller and a chipselect. Most SPI slaves don't support 16 dynamic device discovery; some are even write-only or read-only. 17 18 SPI is widely used by microcontrollers to talk with sensors, 19 eeprom and flash memory, codecs and various other controller 20 chips, analog to digital (and d-to-a) converters, and more. 21 MMC and SD cards can be accessed using SPI protocol; and for 22 DataFlash cards used in MMC sockets, SPI must always be used. 23 24 SPI is one of a family of similar protocols using a four wire 25 interface (select, clock, data in, data out) including Microwire 26 (half duplex), SSP, SSI, and PSP.
