71M6543F/71M6543G Data Sheet
read and properly combined to form the STEMP[10:0] 11-bit value (see STEMP in Table 45 ). The resulting
11-bit value is in 2’s complement form and ranges from -1024 to +1023 (decimal).
The equations below are used to calculate the sensed temperature. The first equation applies when the
71M6543F and 71M6543G are in MSN mode and TEMP_PWR = 1. The second equation applies when the
71M6543F and 71M6543G are in BRN mode, and in this case, the TEMP_PWR and TEMP_BSEL bits must
both be set to the same value, so that the battery that supplies the temperature sensor is also the battery
that is measured and reported in BSENSE . Thus, the second equation requires reading STEMP and
BSENSE . In the second equation, BSENSE (the sensed battery voltage) is used to obtain a more accurate
temperature reading when the IC is in BRN mode. The coefficients provided in the various STEMP
equations below are typical.
For the 71M6543F and 71M6543G in MSN Mode (with TEMP_PWR = 1):
Temp ( ° C ) = 0 . 325 ? STEMP + 22
For the 71M6543F and 71M6543G in BRN Mode, (with TEMP_PWR = TEMP_BSEL ):
Temp ( o C ) = 0 . 325 ? STEMP + 0 . 00218 ? BSENSE 2 ? 0 . 609 ? BSENSE + 64 . 4
Table 45 shows the I/O RAM registers used for temperature and battery measurement.
