The module is built around the MLX90313 IR amplifier-interface, which uses high performance, chopper stabilized amplifiers, providing excellent noise performance. The sensing element is the MLX90247 discrete IR thermopile. The module is delivered factory calibrated. The SPI offers both the sensor ambient temperature and the object temperature in 12 bit digital form. Additionally the module offers several analog pins for access to the programmable comparator circuitry and the reference voltage. 390109060103 Rev. 004 Page 1 of 12 Dec/01 1 page Datasheet MLX90601C SPI IR thermometer module Every write command starts with a high to low transition of CS and ends by a low to high transition of CS after 32 periods of the serial data clock (SCLK). MLX90313C reads the data present on SDI on the rising edge of the clock. With a delay of 8 periods of the serial clock, the SPI will repeat the opcode, address and the first 8 bits of data on pin SDO. This allows the external master to check command and address and terminate the operation in case of an error by forcing CS high before the end of the complete command cycle, i.e. before the end of the 32 clock periods. The read command is build up similarly, except that no data has to be passed of course. On SDO the opcode will be followed directly by the requested data, the address is not returned in this case. The data on SDO is valid on the rising edge of the clock. In case of a read command, the SPI will output the data on SDO starting on the 25th rising edge of the clock (after CS low) as indicated in the figure above. Timing/speed The baud-rate depends on the serial data clock (SCLK) supplied by the master controller and is limited to 125kb/s.
