SPI Communication and the LM70
The LM70 operates in a continuous temperature conversion mode. In this mode, the LM70 operates as a slave device, accepting communication with a host microprocessor. It is an SPI-compatible device that communicates with the host via three signals: chip select (/CS), serial clock (SC), and bidirectional serial data line (SI/O). Synchronous communication with the LM70 is very simple. Because it continually determines the temperature (continuous conversion mode), the LM70 doesn't require that temperature conversion commands be sent from the host, as do other temperature sensors. Also, the SPI communication bus doesn't support multiple devices; therefore, SPI communication with an LM70 requires no packet formation or ...
