1 The different SPI Peripheral Types The SPI peripheral types can be subdivided into the following categories: Converters ( and ) Memories ( and FLASH) Real Time Clocks (RTC) Sensors (temperature, pressure) Others (signalmixer, potentiometer, LCD controller, UART, CAN controller, USB controller, amplifier) In the three categories converters, memories and RTCs, there is a great variety of component. Devices belonging to the last both groups are more rarely. There are lots of converters with different resolutions, clock frequencies and number of channels to choose from. 8, 10, 12 up to 24Bit with clock frequencies from 30ksps up to 600ksps. Memory devices are mostly variants. There are also a few SPI flash memories. Capacities range from a couple of bits up to 64KBit. Clock frequencies up to 3MHz. Serial S SPI are available for different supply voltages (2.7V to 5V) allowing their use in low-voltage applications. The data retention time duration from 10 years to 100 years. The permitted number of write accesses is 1 million cycles for most components. By cascading memory devices any number of bits/word can be obtained. RTCs are ideally suited for serial communication because only small amounts of data have to be transferred. There is also a great variety of RTCs with supply voltages from 2.0V. In addition to the standard functions of a "normal" clock, some RTCs offer an alarm function, non-volatile RAM etc. Most RTCs come from DALLAS and EPSON. The group of the sensors is yet weakly represented. Only a temperature and a pressure sensor could be found. CAN and USB controllers with SPI make it easier to use these protocols on a micro controller and interfacing a LCD via SPI saves the troublesome parallel wiring.
