10 / 16 page 1°C Triple SMBus Temperature Sensor Datasheet Revision 2.3 (04-19-05) 10 SMSC EMCT03 DATASHEET 3.5 Legacy Temperature Data Format Registers 00h, 23h, 01h, 10h, F8h, F9h: For registers displaying legacy temperature data format, the temperature range spans from –63.875ºC to +127.875ºC with 0,125ºC resolution. Temperatures outside this range are clipped to –63.875ºC and +127.875ºC. Data is stored in the registers in 2’s complement as shown in Table 3.7: 3.6 Extended Temperature Data Format Registers FAh, FBh, FCh, FDh For registers displaying extended temperature data format, a value of 64d is subtracted from the Legacy Format output. This effectively extends the range to cover higher external temperature measurements while still maintaining the 2’s complement format. Obviously, the host will have to compensate and add 64d to the read temperature data. This format spans from –63.875ºC to +191.875ºC with 0.125ºC resolution. Temperatures outside this range are limited to –63.875ºC and +191.875ºC. Table 3.8 shows example temperature readings and register content for this data format.
